Backyard Natural Wonders – 2022 Highlights

I love watching nature documentaries like those narrated by David Attenborough, but even more than that I love watching the natural wonders that surround me every day.

This post features a few of my favorite sightings from 2022.

A pair of Eastern Bluebirds eating berries from American Holly (Ilex opaca)

Eastern Bluebirds visit us more often in fall and winter than in spring or summer. In addition to holly berries, they love our heated birdbath, an important source of fresh water in the cold winter months.

I always love it when an animal reminds me of the value of plants or other habitat that humans sometimes question. The male Northern Flicker (Yellow-shafted here in New Jersey) in the photo below did just that while enjoying Poison Ivy (Toxicodendron radicans) drupes, a berry-like fruit in the woods across from our house.

Bottlebrush Buckeye (Aesculus parviflora) is a constant source of entertainment when it blooms in mid-summer, attracting butterflies, Ruby-throated Hummingbirds, Hummingbird Moths, and many different bees and other insects to visit for nectar.

I understood why large long-tongued bees like Eastern Carpenter Bees visited the long, narrow, tubular flowers, but I puzzled over why so many tiny bees would buzz around the plant, since their anatomy isn’t a good fit for the flower size and shape.

As I watched more closely, I saw tiny sweat bees (Halictid species) landing on the anthers (the flower part from which pollen is dispensed) to harvest pollen, both for themselves and to bring to their nests to feed their larvae. Bees and some flies may visit flowers for pollen, an important food source for them. Both their athleticism and creative thinking was impressive.

From a different access point, the sweat bees managed to drink nectar from the flowers, but without their bodies touching the flowers’ reproductive parts, so they weren’t likely to be doing the plant any favors in exchange for the nourishment provided.

The starburst arrangement of abundant stamens (male reproductive parts) in the flowers of Shrubby St. Johnswort (Hypericum prolificum) are such a successful attraction to potential pollinators that this plant doesn’t waste any energy producing nectar.

In late July I found a Striped Hairstreak in our habitat, my first time seeing this species. This butterfly was not only new for me, but it’s rare where I live in New Jersey.  What was it doing in my garden?  Striped Hairstreaks are typically found at forest edges where there are nectar sources, and with nearby access to its caterpillar foods – oaks, walnuts and hickories.  We have nectar sources, and there are suitable caterpillar food trees nearby, so check and check.  

My first ever sighting of a Striped Hairstreak, a butterfly that is rare where I live in New Jersey.

Catbirds arrived in spring and stayed through mid-fall. I saw them just about every day, usually in pairs, but sometimes in groups of four or more. Early one afternoon in August I witnessed a young Catbird being tutored on the proper way to take a bath.

As Flowering Dogwood (Cornus florida), Winterberry Holly (Ilex verticillata) and Blackhaw Viburnum (Viburnum prunifolium) fruit ripened, the Catbirds were joined by migrating birds who passed through, using our habitat as a rest stop.

My favorite event was a visit from a Sleepy Orange in late September.

I love this butterfly for its pioneering ways. It’s mainly a tropical butterfly, but works to extend its range northward, positioning itself for continued survival in these days of climate change.  Instead of the southward migration strategy for winter survival employed by many insect and bird species, some Sleepy Oranges fly north in late summer and fall. I imagine them getting together, looking for volunteers to fly north, saying, “See if you can survive the winter in a place where you can find nectar for yourself and a partner, and food for the kids (caterpillars).  If you succeed, great!  We’ve extended our range. If not, no big deal, we adults will all be dead by late spring anyway.”  I’m not sure that’s what really goes on, but I like to pretend it is.

At one time the Sleepy Orange was thought to be unable to survive the winter any farther north than North Carolina. But they are now seen fairly often in central New Jersey and eastern Pennsylvania, and may have established year-round colonies.  I first encountered a Sleepy Orange in 2006 at nearby Bowman’s Hill Wildflower Preserve, but this was my first sighting of the species in my own habitat.  Very exciting!  This year I had nectar to offer this thirsty butterfly, but to extend its range it needs the food its   caterpillars require, Wild Senna (Senna Hebecarpa, S. marylandica) or Partridge Pea (Chamaecrista fasciculata). I didn’t have the necessary caterpillar food to offer this year, but we’ll have some Wild Senna by next summer.

No matter what time of year, there is always something interesting to see right outside our doors. I have my desk facing the windows so I can be easily distracted by wildlife. Even on a winter day I may see Box Elder Bugs, Chickadees, Titmice, Carolina Wrens, White-breasted Nuthatches, Juncos, White-throated Sparrows, Red-bellied Woodpeckers, Downy Woodpeckers, Robins, Bluejays, Pileated Woodpeckers, Yellow-bellied Sapsuckers, Cedar Waxwings, or Brown Creepers. Some visit for fruit, but many are gleaning insects from the branches, bark and leaves of trees and shrubs, and from the fallen leaves on the ground.

Red-tailed, Sharp-shinned and Coopers Hawks sometimes stop by. On rare occasions, a Bald Eagle does a fly-over.

Want to see more wildlife?  Make your own backyard an inviting habitat. Just provide the food birds, butterflies, bees and other animals need in the form of plants native to your region, and do less: leave fallen leaves in your planting beds, leave spent perennials standing, don’t use pesticides, herbicides or fertilizers, reduce your lawn if you can.  

You don’t need to have a large property to host and see wildlife. We live in an end unit in a townhouse development with a homeowners’ association (HOA), adjacent to commonly owned natural areas that were preserved when the development was built more than 30 years ago. (Note that we leave the leaves, standing spent perennials, and don’t use pesticides.) Even a planter or a window box can bring wildlife within view.

Why travel thousands of miles away from home to see wildlife, when you can make exciting discoveries in your own backyard?

They kept coming, until there was a flock of Cedar Waxwings perched in and around our Winterberry Hollies (Ilex verticillata).

They were here, of course, for the fruit. Cedar Waxwings are especially dependent on fruit in their diet, so much so that ‘Cedar’ in their common name is a nod to Eastern Red Cedar (Juniperus virginiana), whose fruit-like cones are an important source of winter food for this bird. The other part of their common name, ‘Waxwing’, refers to the waxy looking red tips on their secondary wing feathers.

Like most other birds, Cedar Waxwings also eat insects, especially when they are breeding and raising young. I did see one bird take a break from the Winterberry fruit to browse the branches of a nearby Witch-hazel (Hammamelis virginiana) for some insect protein. But fruit was the main attraction for this flock.

While I watched, the birds put on an impressive acrobatic display in pursuit of the delectable fruit.

It’s not by accident that such an abundance of fruit is available for these and other birds. The groundwork is laid in late spring, typically June where I am in central New Jersey, when these shrubs produce a wealth of small flowers that are a major attraction for pollinators, including many different species of bees, wasps and flies.

While they stayed with us, the Cedar Waxwings also ate the remaining Blackhaw Viburnum (Viburnum prunifolium) drupes, as well as some crab apples. The birds moved on after three days, when the trees and shrubs were stripped of their bounty. It was a mesmerizing spectacle while it lasted.  

Cedar Waxwings are typically found in woodland habitats, near water or woods edges, but they are sometimes found in open fields, too. It all depends on food availability. They are sociable birds, and often nest in proximity to other members of their species, with several nests possible in a single ‘neighborhood’.  When they aren’t breeding, they travel in flocks, moving from place to place to find the fruit they need. A few days before the invasion of this flock, I saw one or two Cedar Waxwings in the trees outside.  Because of their gregarious nature, it’s unusual to see a lone bird of this species. Now I can’t help wondering if these early birds were scouts, looking for the next food stop for the group.

To attract Cedar Waxwings to your own yard, be sure to provide the fruit they love.  In addition to Winterberry Holly and Eastern Red Cedar, American Holly (Ilex opaca), Flowering Dogwood (Cornus florida), native viburnums such as Blackhaw (Viburnum prunifolium), Pokeweed (Phytolacca americana), Mountain Ash (Sorbus americana), hawthorns, apples and grapes are all very appealing to this sleek and lovely bird. To see them in summer, offer them blueberries, serviceberries, cherries and blackberries, among other fruit.

Fall Feeding Frenzy!

I have my desk facing the windows of our home office so that I can be easily distracted, and sometimes this strategy really pays off. For the last several days, I’ve had a hard time tearing myself away from my windows because of the steady stream of birds that are visiting to eat the ripe Flowering Dogwood (Cornus florida) and Blackhaw Viburnum (Viburnum prunifolium) fruit from the trees outside.

Both Flowering Dogwood and Blackhaw Viburnum have fruit that looks like a berry but is actually a drupe, a type of fruit that has a fleshy outside, and a single seed inside encased in a stony covering. A peach is an example of a drupe. The fleshy outside is perfect for tempting a bird or small mammal to eat it. The seed goes through the animal’s digestive tract and is later ‘dispersed’ complete with fertilizer to help give a new plant a good start. 

The birds went for the Dogwood fruit first. This seems appropriate, since Flowering Dogwood blooms a few days earlier than Blackhaw Viburnum. A flock of American Robins swooped in to eat, with each Dogwood hosting three, four, five, or more birds at once, bobbing in and out of sight as the branches swayed up and down from the activity.

Other more cautious birds made a swift pass to grab a bite, then flew on to enjoy it in a less congested location. At least three Hermit Thrush stopped by,

and even Yellow-bellied Sapsuckers supplemented their diet with fruit in between their usually forays drilling holes in tree bark for the sap that will ooze out, and for the insects that are attracted to the sap.

Outside, I hear other birds and see them ignoring this bounty of fruit, relying on different food sources.  Brown Creepers and White-breast Nuthatches are active in trees nearby, probing the trunks for insects sheltering in the bark grooves. Brown Creepers start from the bottom of a tree trunk and work their way to the top,

Dark-eyed Juncos and White-throated Sparrows recently returned for the winter. They’re busy probing the bushes and fallen leaves for insects, seeds and fruit. 

While I watched, a Red-tailed Hawk swooped in, scattering the smaller birds, but only briefly deterring them from their foraging. The Red-tail perched nearby for a few minutes, silhouetted against the sky, then left with empty claws.

The Dogwood fruit is just about all eaten now, but the birds are still working on the Blackhaw Viburnum.

Robins are consuming most of the Blackhaw fruit, but the Sapsuckers fly in to supplement their diet, too.  Squirrels are also taking advantage of this feast.

The flower buds that are visible at the same time these plants are offering their ripe fruit promise that the show will continue next year. I just hope that when these plants bloom next spring the bees, flies, butterflies and other flower visitors are as successful as they were this year in pollinating the flowers.

So much action, and I live in a townhouse development in central New Jersey!  Who needs to travel hundreds of miles to see the wonders of nature, when they can be present in your own backyard? Just provide the native plants that the animals we live with depend on. We humans depend on these plants and animals, too.

Why Leave the Leaves?  Ask a Red-banded Hairstreak!

Thinking about doing a fall clean-up in your garden?  Maybe you are planning to remove the layer of naturally fallen leaves that are beginning to blanket your planting beds?

I hope my encounter with a Red-banded Hairstreak will prompt you to change your plans.

On a recent walk on a woodland trail near my home in central New Jersey, I had just turned around to head back to my car when I noticed a flutter of brownish wings at ground level at the edge of the trail. My first thought was that it was probably a moth, but when I saw the insect in profile, I could tell it was a butterfly. As I looked more closely, I saw the tell-tale markings of a Red-banded Hairstreak.  I decided to watch for a while.

She stayed on the ground, walking over obstacles that seemed like they would be a challenge for someone her size, especially when she could choose to fly. While I observed her, she climbed over leaves, rocks, leaf stems and small branches, never once taking to the air.  Several times she paused in place for a few seconds.  Was she just resting, or maybe getting her bearings? No! She had a purpose in mind.

Red-banded Hairstreak caterpillars eat fallen leaves and other decaying plant matter.  This little female was laying eggs on or near the kinds of material that her caterpillars would need to eat when they hatched. She alternated walking for a bit with brief pauses to lay an egg.

After nearly five minutes, she flew off, presumably scouting for another promising location to lay more eggs.

The caterpillars that hatched from her eggs will spend the winter snug in the fallen leaves, waiting for warm spring days to arrive before completing their metamorphosis to become the next generation of Red-banded Hairstreaks.

Since my encounter with the Red-banded Hairstreak in the woods, I’ve seen other individuals in my own shade garden several times.  Fortunately for them and for me, I leave the fallen leaves undisturbed in the garden. I recommend you do the same!

Where do Winterberries Come From?

It’s difficult to walk past Winterberry Holly (Ilex verticillata) when it’s in fruit without noticing it.  The abundant, vividly red, globular, fleshy fruits of this aptly named shrub never fail to catch the eye.

Where do all of those luscious-looking fruits come from?  

Have you ever noticed Winterberry Holly in bloom?

In late spring, Winterberry Holly is covered with an equally large number of somewhat inconspicuous greenish-white flowers. The flowers bloom gradually over a period of a few weeks. 

Like all hollies, Winterberry usually has male and female flowers on separate plants. Only female flowers can develop fruit. Although it isn’t typical, there may occasionally be a specimen with male and female flowers on the same plant, or some flowers that are perfect, that is, they have both male and female parts. Plants often have some variation, as they continue to evolve to try to find the most effective and efficient survival strategies.

Female flowers are usually in small clusters of up to three. The flowers have a single pistil (the female reproductive part) at their center. The green rounded base of the pistil is the ovary. If a flower is successfully pollinated, the ovary will mature, becoming the bright red fruit we see later in the season. The ovary is topped by a stigma, where pollen must be deposited in order for pollination to occur and fruit to develop.

The white arrow- or spade-shaped projections in between the petals of the female flowers are sterile stamens; they don’t produce pollen that can fertilize the flowers.  It’s likely that they help attract pollinators. As these sterile stamens age, they turn brown.

The ovary is at the base, and will develop into a fruit if pollination is successful and the ovules inside are fertilized. The flat-ish tissue at the top is the stigma, where pollen must be placed by an incoming bee or other pollinator.  The white arrow- or spade-shaped projections in between the petals are sterile stamens.

The flat-ish tissue at the top is the stigma, where pollen must be placed by an incoming bee or other pollinator. The white arrow- or spade-shaped projections in between the petals are sterile stamens.

Male flowers often bloom in crowded clusters of up to 10 or more.  The male reproductive parts, called stamens, reach upward from the face of the flower, the anthers at their tips ready to deposit pollen on a flower visitor.

Winterberry Holly needs third party assistance to move pollen from a male flower on one plant to a female flower on another plant, in order to achieve pollination. It may be easy for people to walk past without noticing when these shrubs are in bloom, but fortunately the flowers are enticing beacons to potential pollinators of many different species, especially bees. A recent study showed Winterberry Holly to be among the most attractive to bees of the flowering shrubs.

In my own garden I spotted Bumble Bees, Mining Bees, Sweat Bees, Small Carpenter Bees and a wasp visiting the flowers for nectar rewards. Bees also eat pollen, and female bees may collect pollen to feed their larvae.

Without the assistance of these flower visitors, pollination would not take place, no fruit would develop, and Winterberry Holly would not be able to reproduce. If these pollinators do the job the plants have enticed them to do, fruit develops, ripening by fall.

Birds are the primary target audience for the colorful display of Winterberry Holly’s bright red fruit. Many different species of birds including Eastern Bluebirds,

eat the fleshy fruit and later become the unwitting dispersers of the seeds inside as they deposit them with natural fertilizer when defecating.

Small mammals like mice and squirrels may eat Winterberry fruit, too. People are just the accidental beneficiaries of the bright spectacle, but shouldn’t eat the fruit, which is toxic to humans.

Winterberry Holly fruits contain more carbohydrates than fats, making them less preferred by birds than some other fruit available in the fall. As a result, Winterberry fruit is frequently passed over until later in the season, often well into winter, although sometimes a flock of hungry American Robins or Cedar Waxwings will strip a Winterberry Holly of all its fruit in a matter of hours.

Winterberry Holly is a deciduous shrub or understory tree that grows to a maximum height of about 15 – 20 feet (5 – 6 meters). It prefers moist soil, and is indigenous in bogs and wet woods in the eastern half of the United States and Canada. It makes a great addition to your own landscape for its benefit to pollinators, birds and other wildlife. It doesn’t hurt that Winterberry Holly adds some bright color to a winter landscape.
