Remembering Nature Discovery Day

By Edie Parnum

For eight years I have been gardening for nature on my ¾-acre suburban property. My yard with its abundance of native plants teems with birds, butterflies, bees, beetles, moths, and other creatures both big and small. On August 29 my property abounded with people, too. I had invited nature-loving friends to enjoy my native plants and discover the creatures they support.

Some people came for just an hour, others stayed all day. Most participated in one of the three guided yard tours. The insect and pollinator walks were popular, too. Kids enjoyed their own nature and insect events. A sizable group drove to Barb Elliot’s nearby property and saw her pond and thriving native plant habitat. Some truly nature-crazed individuals stayed after dark for moth night.

Unquestionably, the native plants were a hit. All the species were labeled for easy identification. Many of my favorite plants (Short-toothed Mountainmint, Grass-leafed Goldenrod, Upland Ironweed, Cardinal Flower, Great Blue Lobelia, Garden Phlox, Trumpet Vine, Trumpet Honeysuckle, Large-leafed Aster, and Sneezeweed) were in bloom. Berries on woody plants (Nannyberry and Blackhaw Viburnums, Flowering and Silky Dogwoods, Winterberry Holly, Black Chokeberry) and a vine (Virginia Creeper) were ripe and ready for the fall migrants. (Click here for my complete yard plant list.)

Insects attracted notice and won new converts. Many admired the Monarch and Black Swallowtail caterpillars. The pollinators were active on the flowers. We saw native bees (European Honey bees, too), wasps, flies, beetles, day-flying moths, as well as Ruby-throated Hummingbirds spreading pollen while feeding on the nectar. Our entomologist, Dan Duran, PhD, identified a large blue-winged wasp (Scolia dubia) nectaring on mountainmint. This wasp, a parasite on the larvae of Japanese Beetles, is now a favorite of mine.

The sharp-eyed kids on Debbie Beer’s nature walk saw a migrant American Redstart. By turning over rocks and logs, they discovered slugs and other creepy-crawlies. They also found spiders (the wolf spider was popular), beetles, and a cicada shell—goodies the adults missed.

Vince Smith gave us a geology lesson. My property is composed of Precambrian gneiss and schist, one of the oldest soils on the planet. Because it’s well-drained, the Tulip Poplar, Black Gum, and various oaks I’ve planted will develop deep roots. They should become massive trees and provide wildlife value for decades, perhaps centuries.

Usually I merely write about my yard’s plants and animals and post photos on the Backyards for Nature blog. However, neither words nor pictures are enough. Seeing the natural beauty of my yard and discovering the creatures living there is more powerful.

Many people told me they were inspired to create their own backyard ecosystems. Others vowed a renewed commitment to enhance their developing habitats.

They said Nature Discovery Day was fun. I could see it on their smiling faces.

Edie’s Garden—A Place to Discover Nature

Posted on July 19, 2015 by barb

By Barb Elliot

Wildlife is abundant in Edie’s yard. She finds birds, butterflies, moths, dragonflies, bugs,

beetles, bees, wasps, flies, and more – creatures she loves – living among her native plants.

It wasn’t always this way. I saw the yard when Edie moved to this ¾-acre property in 2007. It was mostly turf grass. Except for a few native trees (Black Cherry, Red Maple, White Pine), no native plants grew here. Consequently, we observed few birds—just an occasional robin or starling—no other wildlife. She knew she could transform her lifeless property into a healthy habitat for wildlife by reducing the lawn and planting native plants. It could become a place where she could discover, learn, and enjoy nature.

To create a healthy ecosystem on her property she wanted to:

Plant a diversity and multitude of native plants
Offer conditions for birds and other creatures to thrive and reproduce
Provide year-round food sources, water, cover, and places to raise young for wildlife
Welcome lots of birds—certainly hummingbirds
Create a place of beauty where she could be immersed in nature
Learn the species of flora and fauna and how they interact and depend on each other
Leave a legacy of nature for future generations with long-lived trees and shrubs

Gradually, year by year, she has succeeded in creating this haven for wildlife. Eight years later I see thousands of native plants. They include perennials, grasses, vines, ferns, and woody plants, i.e. shrubs and trees. She planted densely, letting the plants touch each other as they do in the wild. Her canopy trees are young, but the oaks and others will be massively productive for wildlife for decades. Eastern Redbud, Flowering Dogwood, and Shadbush are already filling the understory. The mature shrubs like Spicebush, Elderberry, and several viburnum species are now luxuriant. At the ground

level perennials, vines, ferns, sedges, and grasses, are profuse. This diversity of plants offer nuts, seeds, berries, nectar, and pollen. Even the foliage of the native plants is indirectly a source of food. Insects eat the leaves and become food for birds and other creatures.

Birds now find what they need to live and thrive. They eat the fruits, nuts, seeds, and nectar produced by the yard’s native plants. Resident and migrating birds eat the insects hosted by her native plants. For example, Carolina

Chickadees can locate the 6, 000-plus caterpillars required to feed their young. Of course, no pesticides are ever used.

Edie has added other features for birds. She installed nest boxes for cavity-nesting House Wrens and Tree Swallows. She allows fallen leaves to lie in many places. Eastern Towhees and Brown Thrashers rummage in this leaf litter to find insects. Carolina Wrens

often locate their insect delicacies in the brush pile. On a snag (dead tree) woodpeckers, including a Pileated Woodpecker, forage for insects in the decaying wood. A Trumpet Vine grows on this snag and attracts hummingbirds seeking nectar from its flowers. A bird bath and small pond offer birds water. The bird feeders supply a small proportion of food needed by some of the birds. Many, many birds (106 species) love this yard.

Her meadow, in my opinion, is the crown jewel of her property. It is chock full of colorful perennials and grasses. Birds forage for seeds in late summer, fall, and winter. Numerous butterflies (30 species so far), bees, beetles, and other pollinators are active on flowers

blooming from April through October. Even at night the meadow is alive with moths, beetles, and other insects and spiders. Aiming a flashlight into the dense meadow plants, she can see the tiny, shining eyes of moths and other insects. Bumble bees, too, sleep on the flower heads, resting for the next day’s work.

Edie has created a paradise for herself as well as the creatures that call her yard home. With binoculars and camera, she frequently takes nature walks around the yard. The birds, whether eating, preening, feeding young, are always interesting. Mating foxes are less expected. Mating Garter Snakes, too. Even

better, she loves to discover a caterpillar eating leaves. When she locates other tiny creatures—bees, beetles, wasps, and others—she takes their photos. At night she uses lights to attract moths. She photographs these creatures, too.

Using the photos of insects, she can usually make identifications and then figure out their role in this ecosystem. What plants do they depend on? What plants depend on them? What do they eat? Who eats them? Are they parasites? Predators?

The possibilities for discovery are endless. Mostly, she revels in success of the healthy ecosystem she has created.

Nature Discovery Day, August 29, 2015

Edie enjoys showing her garden with its native plants, birds, butterflies, moths and other creatures to nature-loving friends. On August 29th she will host Nature Discovery Day. Throughout the day you can explore her yard, discover nature in action, and learn about habitat gardening. Guided walks for children and adults will be offered, too. In the evening it’ll be Moth Night.

This event will be for a limited audience by invitation only. She’s inviting Backyards for Nature blog readers and their interested family and friends. Save the date and watch for an invitation coming to you in late July or early August.

Prime Plants for Nature: Backyards for Nature 2015 Native Plant Awards

Posted on April 22, 2015 by barb

By Edie Parnum

Each year we select two native plant species with exceptional ability to support wildlife. These plants will contribute significantly to the web of life in your yard. They host insects, offer nectar and pollen, and produce fruits, seeds, or nuts. Birds, butterflies, and other insects and animals will feed and prosper. The Prime Plants will provide shelter and nesting places, too. Our selections, all native to southeastern Pennsylvania, are easy to grow and will make attractive additions to your landscape. They are readily available at native plant nurseries or native plant sales. We offer awards in two categories: Trees and Shrubs and Perennials.

Our selections for the 2015 Prime Plants for Nature Awards are:

River Birch, Betula nigra

Wildlife Value: This medium-sized deciduous tree has exceptional wildlife value. According to Doug Tallamy, author of Bringing Nature Home: How You Can Sustain Wildlife with Native Plants, it hosts 411 species of moths and butterflies whose caterpillars eat the foliage. The caterpillars include butterflies such as Mourning Cloak and moths including Luna, Io, Polyphemus, and Cecropia.

Chickadees in Winter

Posted on January 31, 2015 by barb

By Edie Parnum

On cold winter days, watching perky Carolina Chickadees lifts my spirits. Nasty wind, snow, and ice do not deter them. At the window of my warm kitchen with its well-stocked pantry, I wonder how they survive the frigid weather. Weighing only as much as four pennies, they are the smallest birds that visit my feeders. They must be vulnerable to starvation and hypothermia.

Imagining they depend on my beneficence, I diligently keep my feeders filled. My

chickadees land on the feeder with a jaunty bounce. They never stay on the feeder perches to eat speedily like the House Finches. The finches have large, strong beaks to break open seeds and can quickly chow down multiple seeds. Instead, chickadees use their tiny beaks to pick out an individual seed and carry it to a nearby branch. Holding it with their feet, they pound with their bills to break open the shell and access the meat. They repeat this again and again. Being a chickadee is hard work.

I enjoy watching chickadees in the wild, too. Yes, I do go outside in winter—my down jacket keeps me warm. Walking through the woods, I often hear their “chickadee-dee-dee” call before spying them. Sometimes merely a soft “sit-sit” sound alerts me. In winter chickadees, along with Tufted Titmice, are leaders of a mixed flock of birds. These little sounds help the birds stay in touch as they roam a mile-wide circle. The flock usually includes White-breasted Nuthatches and Downy Woodpeckers. Sometimes Hairy Woodpeckers, Brown Creepers, kinglets (both Golden-Crowned and Ruby-Crowned), and others tag along, too. The chickadees and titmice have this following because they are exceptionally alert to predators and adept at finding food.

Chickadees search for food all the time. Using their beaks they continuously probe the crevices of bark, branches, and buds. Little acrobats, they use their strong claws to hang upside down and investigate the undersides of branches and other vegetation.

Even with my binoculars, I can’t see what the chickadees are eating. Their eyesight is keener than humans’. With twice as many receptors in their eyes and the ability to see ultra violet light, they locate their prey: tiny, camouflaged eggs, larvae, and other hibernating insects and spiders.

Scientists tell me fifty per cent of Carolina Chickadees’ winter diet comes from these dormant creatures. Insect food is proportionately higher in fat and calories than plants. Nevertheless, they relish the sunflower and safflower seeds at my feeders. Sometimes they eat suet and peanuts, too. In the wild they consume seeds, berries, and cones. Frequently I observe them devouring seeds while dangling from the balls of a Sweet Gum tree next to my house. Native plants like Eastern Red Cedar, Poison Ivy, Eastern White Pine, Tulip Poplar, and various birches and goldenrods are favorite foods in my yard and beyond. They cache some food items, remembering the location to retrieve when needed.

Chickadees possess special adaptations to withstand the cold. Before the winter season starts, they grow 50% more feathers. To minimize heat loss they fluff up their feathers to

create air pockets—I think of my down jacket. Researchers say, however, shivering is the primary way chickadees maintain their body temperature.

Carolina Chickadees’ most difficult challenge is to survive the long, cold winter nights. I spend my nights in a heated house covered with layers of blankets—oblivious to the possibility of freezing to death. At night a chickadee will roost singly in a cavity or dense vegetation—seemingly an inadequate strategy for retaining body heat through the night. It can, however, lower its body temperature by 10 degrees to minimize loss of calories. Remarkably, chickadees can endure temperatures as low as -35 degrees.

I wonder if feeding the chickadees and other birds helps them survive the winter. They obviously like my well-stocked feeding station. Before, during, and after snowstorms, birds flock to my feeders in especially large numbers. They can’t access their natural food items when covered with snow, especially when coated by ice. Nevertheless, chickadees using feeders do not become addicted to “bird” seed. They rely on insects and plant food in the wild as well. In fact, chickadees living in remote areas depend completely on natural food. Their survival rate is almost as high as for birds whose diets are supplemented at feeders. Chickadees probably do not require my assistance.

Alas, many chickadees do die during the winter. Despite their impressive adaptions to the cold, 50% don’t survive. We shouldn’t worry, however. The healthiest, best adapted will live to breed in the spring and lay 3-10 eggs.

Now in late January, chickadees still have weeks of freezing winter ahead. Nevertheless, the chickadees know the daylight hours are getting longer and spring is coming. Already, I’ve heard them sing “see-bee, see-bay,” their mating song. They are practicing for the breeding season when they will attract a mate, defend a territory, build a nest, lay eggs, and feed their young. I take heart, chickadees will survive and thrive for years to come.

Want More Native Plants? Learn to Transplant

Posted on October 22, 2014 by barb

By Edie Parnum

You read it repeatedly on this blog—plant more native plants. Plant lots of them. Too expensive, you say. That’s true when you purchase them at nurseries or native plant sales. I know where you can get native plants for free—yes, really! They are already in your own backyard.

Local native plants are adapted to our soil and climate, so they reproduce abundantly. Look carefully at the young plants in your garden. You’ll find multiples of many of your favorite native plants. Resist pulling out these volunteers and throwing them away. They are not weeds. Keep them growing by transplanting them to new locations.

Take a tour around your yard. Locate the native plants that have popped up voluntarily, but haphazardly. These young woody saplings and perennials are smaller versions of plants you already know and love. Many, you recall, are particularly favored by birds, butterflies, and other creatures. Others are your personal favorites—they are so beautiful! You already know their ultimate size, shape, and color and their needs for sun, shade, dry, or moist conditions. These native plant treasures can be saved by moving them to new locations.

Now look for places where you can incorporate these volunteer trees, shrubs, perennials, ferns, vines, and groundcovers into your landscape. Where can you grow another tree? How about several trees? Shrubs can be added around the base of isolated trees. Can you install or expand a garden bed? What about removing some non-native plants or invasives? Keep in mind native plants prefer to touch each other, not be isolated. Spots of bare ground should be filled in with native groundcovers. And, surely, your lawn can be reduced. Aim to cover virtually all open areas with native plants.

Be brave. Dare to transplant—even if you’ve never done it before. Native plants are resilient and determined to grow. Spring or fall, here’s how to transplant.

Directions for transplanting tree or shrub saplings

Locate a small sapling, preferably shorter than 15”, to transplant. If the soil is dry around the plant, water it well.
Before you dig out this woody plant, select the location where you want it to grow and dig a hole there. This hole should be no deeper than the expected depth of the transplant’s roots and about twice as wide.
To dig out the transplant, estimate the size of the root system (usually as wide as the sapling’s canopy). Dig deeply around the plant and avoid severing the tap root. When you lift the sapling out of the ground, it should have plenty of roots and soil attached.
Carefully lay the sapling with its root system on a piece of newspaper or plastic and carry it to the new location.
Place the plant into the pre-dug hole. Hold the plant upright with the top of the root system ½” above the height of the ground. Fill in around the roots with the soil that was removed from the hole. Do not add fertilizer, topsoil, or other amendments. Press the soil down with your hands, but do not stomp with your feet.
Spread compost and leaf litter on top.
The sapling of this 10-foot White Pine was 6 inches tall when transplanted five years ago.
Water well. Unless it rains, water the transplant every week for several months—longer if the season is dry. In fall, water until the ground freezes.
Some established shrubs such as viburnums send out horizontal roots where new plants can emerge. These baby shrubs can be transplanted, too. Follow the directions for free-standing saplings. However, before digging the plant out of the ground, find and sever the lateral root growing out from the mother plant.
Small woody transplants, once established, grow quickly. After a few years they will be as big as much larger nursery-grown trees and shrubs.

Personally, I have successfully transplanted Red Maple, Bottlebrush Buckeye, Redbud, Eastern Red Cedar, Tulip Tree, Eastern White Pine, Black Cherry, Tulip Tree, and Sassafras. I’ve also moved several native species of dogwoods, hollies, oaks, and viburnums. Most other native woody plants will transplant well, too. You can also relocate woody vines like Virginia Creeper, Trumpet Vine, and Virgin’s Bower.

Directions for transplanting perennials

Perennials and other non-woody plants often produce volunteer seedlings. These young plants resemble their parents and can be readily differentiated from your yard’s common weeds. Frequently I see Nodding Onion, Anise Hyssop, Amsonia, Wild Columbine, Wild Geranium, Cardinal Flower, Great Blue Lobelia, False Sunflower, Golden Ragwort, New York Ironweed, Golden Alexander—all valuable plants begging to be saved. I often find my cherished native asters, goldenrods, and phloxes as seedlings, too.
You can dig out these and many other seedlings and transplant them elsewhere. Follow the above directions for transplanting shrubs and trees.

Some perennials spread by underground runners. The lateral roots of Mountain Mint, Bee Balm, Monarda, Wild Bergamot, Obedient Plant, Ostrich Fern, and Mistflower produce growth to dig out for new plants.
Divide older perennials. Look for plants that are oversized and have lost vigor. These can and should be divided. Push your spade deeply into the ground at several places around the perimeter of the large plant. Lift it up out of the ground with most of the root system intact. Thrust your shovel into the middle of the plant and separate it into two clumps. If the root system is dense, you can use two back-to-back garden forks to pry it apart. Further subdivide these clumps to yield four or more plants.
As with woody plants, plant perennials and ferns ½ inch higher than the ground. Be sure to keep them watered until they are established. If planting late in the fall, mulch the plants to prevent them from heaving out of the ground during light frosts.

With the right transplanting tool, the work is not hard nor especially time consuming. You

certainly can dig out a plant satisfactorily with an ordinary shovel. However, I prefer using my transplant shovel. With its narrow blade I can make precise cuts around my target plant but avoid injuring desirable plants nearby. It has a wide ledge for stomping with my foot and good leverage. Thus, I’m able to do most of my transplant operations standing up. No need to kneel or squat uncomfortably.

You can’t create the landscape of your dreams all at once. Each spring and fall, transplant as many young plants as you can. Ever increasingly, your property will include all the layers found in nature: groundcovers, perennials and ferns, shrubs, understory trees, and canopy trees. This dense, layered landscape will develop into a rich habitat alive with insect and animal biodiversity.

A layered landscape in fall, including Virginia Creeper and violets as ground covers, asters, amsonia hubrectii, Solomon’s Seal in its fall yellow color in the background, Fringe Tree (understory tree on right), and a large Common Hackberry tree (on left).

Revel in the fecundity of your garden. Each of your native plants is a gift to nature. Each with its leaves, flowers, seeds—in fact every part of the plant—contributes exuberantly to the web of life. Save them one by one to plant elsewhere in your yard. Give them away, too. Your garden will be a native plant nursery.

New Books on Gardening for Nature

Posted on September 29, 2014 by barb

Reviews by Edie Parnum

Want to become a better steward of nature on your land? These two books will inspire and guide you. Doug Tallamy’s popular book, Bringing Nature Home: How You Can Sustain Wildlife with Native Plants, taught us to love native plants for the leaf-eating insects they host. Tallamy has now teamed up with landscape architect Rick Darke on a new book that helps us create aesthetically pleasing landscapes for our native creatures. Heather Holm’s book teaches us to garden for insect pollinators and appreciate the ecosystem roles they play. We can help the environment by what we plant in our yards. These books tell us how.

The Living Landscape: Designing for Beauty and Diversity in the Home Garden by Rick Darke and Doug Tallamy

This book is beautiful—so beautiful you can display it on your coffee table. The photographs show landscapes, combinations of native plants, and the creatures who live there. These images inspire us to create esthetically pleasing wildlife habitats that are alive with biodiversity.
The pictures and text explain how to design for beauty using native plants. Instead of planting them haphazardly, we learn to position and combine natives to create an alluring garden.
The authors teach us to imitate natural habitats by planting in layers: ground, herbaceous, shrub, understory, and canopy.
Instead of photos of individual plants, the book illustrates native plants as part of the landscape and showcases the birds, butterflies, and other creatures living there.
Edie’s meadow landscape, September, 2014. © Edie Parnum.
A practical book, low maintenance gardening is emphasized. It recommends pleasing combinations of plants that don’t out-compete each other or require excessive weeding. We learn to anticipate changes in our landscapes over time, especially when planting trees and shrubs.
The plant lists, organized by geographical area, are superbly designed to help us make plant selections. Symbols concisely indicate the ecological functions for each plant, e.g., nest sites, pollen, nectar, seasonal foods for birds, and food for caterpillars. Other symbols represent landscape functions such as seasonal flowering, fall foliage, fragrance, or groundcover.
The plant lists also specify the ecological benefits to humans. Not normally emphasized, these paybacks include carbon sequestration, shading and cooling, watershed protection, moderation of extreme weather, and air filtration.

Pollinators of Native Plants: Attract, Preserve and Identify Pollinators and Beneficial Insects with Native Plants by Heather Holm

Like flowers? You surely love pollinators, too! You can’t have one without the other. Plus, flowers and their pollinators create seeds, fruits, and nuts—actually a third of the food we eat. Of course, animals of all kinds require these food products, too.
Butterflies, the most charismatic of the insects attracted to flowers, already have fans. Now, with this book, we also learn to value pollinating bees, wasps, moths, flies, and beetles—really!
The bulk of the book describes the best pollinator-attracting plants and the interactions between their flowers and the pollinating insects.

Insect pollinators are fascinating. We can easily observe and identify them by watching the book’s featured flowers and examining their insect visitors. The excellent photographs in the book help us identify these bees, flies, and other insects. Then we can observe each insect’s strategy as it probes for nectar and/or collects pollen. We may see insect interactions like predation, copulation, and parasitization, too.

Using this book we home gardeners can select pollinator-attracting plants for the various growing conditions on our properties.
By planting Holm’s recommended pollinator plants and observing pollination in action, we will revel in the flourishing ecosystem we’ve created.

I highly recommend both of these books. They will help you beautify your garden and increase its ecological value for all the creatures who inhabit it.

National Moth Week: Why? What Good are Moths?

Posted on July 18, 2014 by barb

By Barb Elliot

Moths, really? Yes, we’ll celebrate moths this coming week, July 19 – 27. During National Moth Week public and private moth-watching events will occur. Mothing, the practice of attracting, viewing, and photographing moths is growing immensely in popularity. But some are puzzled and ask, “What good are moths?” Butterflies are great, but moths are nasty. After all, moth caterpillars eat tomato plants, make holes in wool clothes, eat flour and cereal in our kitchens, and can be agricultural pests. This is all true, but harmful moths are but a small fraction of moth species. Most are actually very important and beneficial to the environment.

In fact, moths are closely related to our much-loved butterflies. Both are in the scientific order Lepidoptera, meaning “scaly wings”. All butterflies and moths have four wings covered with colored scales. Both groups go through four life stages: egg, larva (caterpillar), pupa (chrysalis/cocoon), and adult (butterfly/moth). Adult butterflies and moths also have a proboscis – a thin, straw-like tube for sipping nectar. However, all butterflies fly during the day, but most moths fly at night. The tips of butterfly antennae are club-like, while moth antennae are

more varied in structure. . Some moths have hairy-looking elongated scales on their bodies. These may provide greater protection from the environment and help them maintain their temperature – useful on cool nights.

But what good are moths? Widespread and numerous (nearly 13,000 species in the U.S. vs. just 1,000 butterfly species) they play key roles in ecosystems. As pollinators of night-blooming plants, they are very important. Unlike bees, moths do not eat or gather pollen. However, their hairy bodies collect and spread pollen as they move from plant to plant.

Many plants depend on this nocturnal pollination to maximize seed production. A few cannot reproduce at all without moth pollination. The proboscis of some moths can be many inches long, enabling the moth to reach nectar at the end of elongated flower tubes that are too long for bees.

Moths, both adults and caterpillars, are key food sources for many animals. Other insects, spiders, birds, bats, frogs, toads, lizards, rodents, foxes, and even bears consume moths. As indicators of biodiversity and the health of our environment, they function as “canaries in the coalmine.” Almost all moth caterpillars require specific plants as food. Less diversity in native plants means less food for moth caterpillars and therefore, fewer species and numbers of moths. The result — less food to power the web of life.

Many moths are beautiful, like the lovely Luna Moth. Less impressive moths are often masters of mimicry or camouflage. Some mimic scary-looking animals such as snakes. Others, such as the Io Moth, have huge “eyes” to startle predators. Some look like bark, dead leaves, lichens, or even bird droppings– making it almost impossible to spot them.

I find moths to be downright interesting creatures. For instance, the beautiful and large adults of the Giant Silk Moth family have captivating life histories. These moths, such as the Luna, Tulip-tree, Cecropia, or Polyphemus, live for only a week or two — just long enough to attract or search out mates and for females to lay eggs. With reduced mouthparts, these moths are unable to eat. Females emit chemical scents called pheromones to attract males. Males in this family have large, feathery antennae to detect pheromones from as far as seven miles away. They want to make a beeline to the female!

Moths come in a variety of shapes and sizes. Some are as tiny as the tip of a pencil. The Cecropia Moth (shown above), our largest moth, has a 6” wingspan. Some rest with their wings flat. Many hold them vertically like some butterflies. Others fold them like tents over their bodies.

A few curl their abdomens up above their wings, an odd posture that is likely part of their mimicry or camouflage. Sphinx or Hawk moths display outstanding flight dynamics. They can fly very quickly, hover, and move rapidly from side-to-side. In fact, the flight aerodynamics of some Micro-aerial Vehicles’ (MAVs) are being designed by the military to emulate Sphinx moth flight.

Both Edie, my Backyards for Nature colleague, and I now consider ourselves to be “moth-ers”. We frequently have “moth nights” in our yards. We attract the moths by shining special lights onto a white sheet, a place where they can land. By painting fermented bait onto tree trunk, we can attract moths that don’t come to lights. We follow Moths of the Eastern United States on Facebook and note what moths are being seen by other enthusiasts. In June, Edie and I attended Mothapalooza, a weekend moth conference in Ohio. With 150 participants, it sold out within two weeks of being announced – a testament to the burgeoning popularity of mothing. We visited five mothing stations that hosted thousands of moths. We were up until the wee hours, but had great fun.

Try mothing yourself. At first keep it simple. Leave your porch light on for the evening. Go out periodically to see what moths have flown in. With a flashlight, look for moths nectaring on your flowers. Fragrant, white, and pink flowers are particularly alluring. Look closely,

and you’ll see each moth using its proboscis to suck up nectar. Or, put out a plate of rotting fruit and check for moths that stop by for a sugary drink.

Invite family and friends for a moth night in your yard. See Edie’s Moth Night blog post from last year for moth night ideas, a bait recipe, and host plants for moth caterpillars. Check the National Moth Week website for public events in your area and tips on finding moths. All across the United States and in many countries of the world, moth-ers will be celebrating moths.

Moths are good! They play key roles in the web of life. Plus, they are fascinating creatures. These gems are outside your door at night. Try mothing, but I warn you that it can become addictive. Like a treasure hunt, you never know what may fly in. Become a moth-er and … welcome to the dark side!

Looking for Nests

Posted on July 3, 2014 by barb

By Edie Parnum

Nests are hard to find. Sure, it’s easy to see the House Wrens and Tree Swallows come and go from the nest boxes I have provided. Most songbirds, however, build and raise

their young in well-concealed cup nests. Paying particular attention to the dense areas, I examine my trees and shrubs. I look, too, for lumps in the crotches of trees. I strain to see high in the canopy. The breeding season is well underway, but I’ve found only two cup nests on my ¾-acre property.

Early this spring a female Robin built a nest out of grass, sticks, and mud in a dense holly below my raised deck. I could look down and see her settled in the nest. Once I glimpsed four pale aqua eggs. Here was an opportunity to learn more about the nesting behaviors of the American Robin. From a comfortable but hidden vantage, I planned to observe the mother robin incubate her eggs, then watch both parents feed the nestlings. Not so. One day the female and the eggs were gone.

Plenty of predators prowl around my yard. A ravenous jay, crow, raccoon, possum, snake, or even chipmunk might have devoured the eggs and destroyed the nest. Last year Gray Catbirds screeched hysterically when a Blue Jay ate their eggs.

Besides the Robin’s, a Mourning Dove’s nest was high in my in my crabapple tree this spring. While my nature-loving arborist was removing winter-damaged limbs, he exposed a flimsy nest with two eggs in the crevice of a broken branch. He left it undisturbed. From the ground I could glimpse a Mourning Dove’s eye peering at me from above the

limb. Again, I hoped to watch and study the birds’ breeding routine. After a few days of viewing the brooding dove, however, I could no longer see the bird nor any activity. Why did the nest fail? Perhaps the arborist’s intrusive activity caused delayed nest abandonment. Of course, a predator could easily have seen and raided the exposed nest. Thankfully, both the doves and robins will nest again—successfully, I hope.

Besides searching for nests, I’m also watching for signs of breeding. Catbirds, cardinals, house finches, song sparrows must be breeding here. Pairs of birds, singing loudly and persistently, cavort in my yard. Some birds carry nest material. Others have insects in their beaks. When they don’t eat the food, they’re carrying it to a nest—a sure sign of breeding. I hope to discover the nest where nestlings are being fed.

Though I have not seen it, I believe a pair of Brown Thrashers has a nest on my property. Most suburban yards don’t host Brown Thrashers, especially not a breeding pair. Thrashers like dense shrubbery, not the typical manicured landscape. With their bills they sweep and probe the ground searching for insects and spiders in last year’s fallen leaves. I was plenty pleased when a Brown Thrasher spent the winter in my yard. This reddish-brown, jay-sized bird with a streaked belly stayed silent and sheltered in the arborvitae and other dense vegetation. Every few days I saw it stray from its hiding place and feed on exposed ground. I assumed it would move on in the spring to breed elsewhere.

In mid-May, a Brown Thrasher, possibly the same bird, sang vociferously from the treetops. Its loud doubled phrases are different from its close relative, the smaller Northern Mockingbird. The purpose of the song is to attract a mate and defend a breeding territory. Even so, I assumed my wintering bird (or new arrival) was just practicing and would not stay to breed here. When the singing stopped a week later, I concluded it had departed.

To my surprise in late May and June I’ve occasionally glimpsed a soundless thrasher. Males and females are indistinguishable, but sporadically I have seen two birds together. Could a pair be breeding after all? The thicket of forsythia and blackberries at the back of my property is perfect for thrashers. Every few days I spend a few minutes peering into the undergrowth and listening. Once I saw it deep, deep inside the dense vegetation. On another occasion I discerned a barely audible whisper version of the thrasher song. According to my research, thrashers are mostly silent during the nesting season but sing softly in the vicinity of a nest.

Surely thrashers have a nest in my shrubbery. It is probably just a few feet off the ground, but hidden in the impenetrable thicket. My chances of discovering it are slim. Because they consider me a potential predator, the birds probably engage in evasive behavior to lead me astray. Undeterred, I keep looking and listening.

I need a vigilant, alert ornithology student to help find the nest. A sharp-eyed young person could spot the bug in the thrasher’s beak. Together we could find the nest. See the baby birds. Watch their parents put insects into gaping mouths. Observe the naked babies grow pinfeathers followed by juvenile feathers. We would thrill to witness them fledge and take flight into the world of my backyard. Alas, without my student, I evidently can’t be a voyeur of birds’ private lives.

By searching for nests, I’ve learned more about helping breeding birds succeed. I’ll plant more dense shrubs where birds can build and protect their nests. These shrubs will be insect-hosting natives instead of the non-native forsythia. Already I do not tidy up the thickets and corners of the yard. Thrashers and other ground-feeding birds require the leaf litter to feed themselves and their offspring. Next fall I’ll welcome leaves into the perennial beds, too. And, most important, I’ll grow more native plants where birds can find plentiful insects to feed their young.

In some ways I’m unable to help and must trust the birds’ own survival abilities. Predators abound, but the birds possess skills to protect their nests, eggs, and nestlings. Vigilant and ingenious, they know how to keep their nest locations secret. Thankfully, when a nest fails, most are able to produce a second brood.

It’s summer now, and I see lots of baby birds around the yard. The nests are somewhere nearby. Birds are breeding here successfully.

Let’s Celebrate National Pollinator Week! June 16 – June 22, 2014

Posted on June 18, 2014 by barb

By Barb Elliot

Pollinator Week* is a good time to watch, celebrate, and be thankful for pollinators. After all, they are responsible for every third bite of our food and drink. They pollinate crops, trees, shrubs, and flowers in our landscapes for free. I’m having fun observing pollinators

as flowers bloom on my native trees, shrubs, and perennials. Native bees, beetles, wasps, and butterflies are busy during the day, and after dark I’m finding moths and other nighttime insects visiting my flowers. Pollinator Week is a good time to take a walk in your yard, look for flowers with pollinators, and watch them as they work.

It’s also a great time to do something for pollinators! Facing multiple threats, including habitat loss, pesticides, and diseases, they certainly need our help. The simplest and best

thing we can do to help is add some pollinator-friendly native flowers to your landscape – even if it’s just a few plants in a pot. Do even more by taking the Pollinator Pledge through The Xerces Society Bring Back the Pollinators program.

For a list of pollinator-friendly plants and more information about pollinators, reasons for pollinator declines, and other simple actions you can take, see my March 24, 2014 post Pollinators Need Our Help!

(*Established in 2007 by the Pollinator Partnership, Pollinator Week “has grown exponentially in scope each year with this year June 16-22 being designated by U.S. Secretary of Agriculture Tom Vilsack and 44 governors as a week to celebrate and protect the nation’s pollinating animals.”)

Prime Plants for Nature: Backyards for Nature 2014 Native Plant Awards

Posted on May 5, 2014 by barb

By Edie Parnum

Each year we select two native plants with exceptional ability to support wildlife. These plants will contribute significantly to the web of life in your yard. They host insects, offer nectar and pollen, and produce fruits, seeds, or nuts. Birds, butterflies, and other insects and animals will feed and prosper. Most provide shelter and nesting places, too. Our selections, all native to southeastern Pennsylvania, are easy to grow and readily available at native plant nurseries or native plant sales. Our Prime Plants make attractive additions to your landscape. We offer awards in two categories: Trees and Shrubs and Perennials.

Our selections for the 2014 Prime Plants for Nature Awards are:

Eastern Red Cedar, Juniperus virginiana

Wildlife Value: This small evergreen tree is a powerhouse for nature. Yellow-rumped

Warbler, Eastern Bluebird, and Northern Mockingbird are among the 54 species of birds that eat its long-persisting berry-like cones during the cold months. Cedar Waxwings areso-named because they’re fond of cedar cones. The foliage hosts the Juniper Hairstreak butterfly, a vulnerable species in Pennsylvania, and several species of moths such as the Curve-lined Angle. Song Sparrows and other

birds use the dense foliage for nesting places and shelter. Don’t be tempted to buy the similar-looking Leyland Cypress, a non-native that offers little for wildlife.

Growing Conditions: The Eastern Red Cedar tolerates a wide variety of soils and dry to moist growing conditions. It prefers a sunny spot. These trees are either male or female. Only the female trees produce fruits, but you’ll also need a male for pollination.

By planting at least three of these trees, you will enhance their wildlife value. A row of cedars will provide dense shelter for birds. From the human perspective, the cedars can offer privacy. If planted on the north side of your house, they will create a windscreen.

Appearance: This evergreen has a pleasing conical shape. It grows at a moderate rate (1-2 feet per year) and reaches 15-40 feet at maturity.

Short-toothed Mountain Mint, Pycnanthemum muticum

Wildlife Value: This perennial is a magnet for pollinators. Butterflies, bees, wasps, and flies are attracted to the copious nectar and pollen this lovely plant produces. Because it

flowers over a long period of time, it may host thousands of visits by pollinators each season. With this plant in your yard, you can introduce children to pollination and teach them not to be afraid of bees and wasps.

Growing Conditions: Mountain Mint is a tough plant and will grow well in dry to moist soil in full to part-sun. Like other members of the mint family, it spreads but can easily be controlled, especially early in the growing season. It’s easy to transplant and share with other native plant gardeners. This perennial is deer-resistant, too.

Appearance: Mountain Mint grows to about 3-feet tall. Although the numerous flowers are small and inconspicuous, the foliage is an attractive silvery grey. The leaves complement other brightly colored flowers in the garden and in flower arrangements, too. This plant’s attractiveness is enhanced by the beautiful butterflies and other pollinating insects that visit.
