Winter’s Arrival

A quiet trail in Minneapolis, Minnesota, glows with fresh snow and late-afternoon sun.

The “keeper snow” came early this year. In late November, we walked in lightweight clothing and running shoes. Two days later a storm blew in ahead of a Canadian cold front and dropped eight inches of new snow. We’ve entered the stark season. Green is a memory buried under an ice-cold blanket. Gone from our yard are the bumblebees, painted lady butterflies and other pollinators. I’ve put the garden to bed for the winter.

Black-capped chickadees (Poecile atricapillus) are high-energy winter residents in our back yard.

Just ahead of the storm, a mixed flock of robins, dark-eyed juncos, black-capped chickadees and small woodpeckers—both downy and hairy—descended into our back yard. Robins tossed aside leaves to uncover stray insects, seeds and fruit. Juncos sought seeds on the garden wall. Chickadees and woodpeckers hunted for insect larvae and other delights in the bark of our old apple tree.

This afternoon at dusk, a female northern cardinal, softly colored and alone, delicately plucked crabapples one-by-one in our front yard. She was lucky to find any because the portly gray squirrels have stripped most of the tree bare. I am grateful for these winged winter residents that bring life to our garden on even the coldest winter days.

Robins and Apple Blossoms

Spotting a robin in March signaled the onset of spring to me as a child. We had a “Golden Book” titled, Birds: A Child’s First Book About Our Most Familiar Birds. It featured drawings of neatly woven nests cradling delicate eggs and portraits of familiar garden birds. Illustrations often showed robin nests built in blossoming apple trees and that image, along with the robin’s melodic songs, became synonymous with spring in my young mind.

Decades later, my husband and I bought our home in Saint Paul. Our first evening there, we sat on the back stoop beneath a beacon apple tree that’s now more than 80 years old. Two adult robins flew in and out of its leafy crown indicating the presence of a nest. A chorus of high-pitched chirps greeted the parents as the hatchlings anticipated dinner, their tiny heads stretching over the nest’s rim. During the next few weeks, we were privy to nestling squabbles, flight training, food procuring and the proper way to down a worm!

Some say that red-winged blackbirds (Agelaius phoeniceus) are the new sign of spring’s return to Minnesota. Robins now winter in the state and I hear their sweet songs on milder midwinter days. Many birds can withstand very cold weather as long as they find enough food to fuel their metabolic rate. Gardens often feature crabapple, mountain ash, dogwood and other fruit eaten by wintering birds. City boulevard plantings include fruit trees and larger trees like hackberry. I frequently see large groups of wintering robins dart between the crowns of boulevard hackberries near Saint Catherine University in Saint Paul. Robins also eat bird feeder food during winter that they wouldn’t touch in other seasons. Many a robin has dined with the woodpeckers at our suet feeder!

Sometimes I wake up to robin song drifting in through my bedroom windows in the predawn darkness. I remember childhood mornings of their pure, lovely caroling along with the scent of lilacs, the touch of humid air and perhaps thunder rumbling in the distance from an early morning storm. These are joyful memories — and though robins often ride out the winter in Minnesota, their clear singing, and the beauty of apple blossoms, still signify spring to me.

Who Will Nest Here?

Black-capped chickadees, downy woodpeckers and white-breasted nuthatches recently explored this cavity in our apple tree.

Our beacon apple tree is pushing 80 years old. It’s dropped a few limbs over time; some splintered under the weight of apples, others weakened with age and rot. One old limb bears a small cavity. “So what?” you think —  unless you’re a chickadee, nuthatch or other cavity dweller looking for a nesting site. All three species frequently explore and tussle over this cavity, and I believe the chickadees are winning.

One sunny, frigid afternoon, a downy woodpecker pair ducked in and out of the cavity and were confronted and chased away by a black-capped chickadee. A curious white-breasted nuthatch also sidled over for a peek and was waved off by the chickadee. Later, three chickadees fluttered around the opening until two chased off the third. The remaining pair excavated and removed wood chips from the cavity interior; evidence they are preparing a nesting site! The male sings his territorial “fee-bee” (sometimes “fee-bee-bee”) song. I first heard him sing on December 31. 

One member of the black-capped chickadee pair (Poecile atricapillus) removes wood chips from the apple tree cavity.

Chickadees deposit excavated wood chips away from the nest site to avoid leaving signs for predators.

Will this pair nest in our apple tree? Black-capped chickadees prepare multiple nesting sites before the female chooses one, so we won’t know for a few weeks. Wherever they nest, the female will line the tree cavity with moss, soft plant fibers, feathers, hair and fur. She will lay 1-13 (usually 6-8) white eggs marked with reddish-brown spots. The female incubates the eggs and the male feeds her on the nest. Once the hatchlings are old enough to be alone for a short time, both parents feed them. Insects (including their eggs and caterpillars) and spiders comprise most of their high-protein summer diet. Black-capped chickadees also eat other small invertebrates, seeds, nuts and berries. They’ll visit seed and suet feeders in the winter. One cold afternoon, as I topped off our sunflower seed feeder, a cheeky chickadee landed on the edge of my filling-cup, snatched a seed off the top and flew into our arbor vitae hedge to either eat its treat, or cache it for another day.

Black-capped chickadees remain in Minnesota year round.  They are common in much of the northern United States and most of Canada.

I enjoy the chickadees’ curiosity, high-energy antics and their melodious breeding calls, especially as winter drags on. Stay tuned to find out whether or not they nest in our apple tree.

January Silence and Sound

Male cardinals (Cardinalis cardinalis) typically begin singing during mid-January in Minnesota. (I photographed this fellow on a sunny winter morning.)

The weight of winter silence presses on my ears. Heavy snowflakes drape tree limbs, topple seed heads and cover squirrel nests with a crystalline blanket. Falling snow absorbs the whir of auto engines, which pass almost noiselessly down the street. Even the incessant hum of the airport is muffled.

Suddenly, in the snowy hush a northern cardinal sings: “What cheer-cheer-cheer-cheer.” He repeats his joyful song four times and falls silent. His call momentarily illuminates the quiet. His red brilliance punctuates the black, gray and white of a January snowfall.

It is the first time I’ve heard a cardinal sing since last summer. In Minnesota, they typically begin singing in mid-January and will soon renew pair bonds and breeding territories. I welcome his upbeat melody that, along with the lengthening daylight, signals another milestone on the journey to spring.

Early Spring Native Flowers: Hepatica

This year, I look for spring close to home. I haven’t hiked in a nature preserve yet, and we’ve stayed home from our cabin. I miss those places, but I’m enjoying many simple delights right here, including a few native spring flowers. While bloodroot blooms fade, another spring native, hepatica, buds and opens.

Round-lobed hepatica (Hepatica nobilis) blooms range from white to purple in color.

Hepatica, liverleaf, or liverwort, is named for its leaves that are three-lobed and can be a brownish-bronze color (like the human liver) at winter’s end. Each spring, the fuzzy flower stalks push up through the old leaves to bloom in pastels ranging from white to purple. In Minnesota, hepatica can begin blooming anytime from early April into May — before the trees leaf out. Bees, early butterflies, beetles and flies pollinate the small flowers depending on how early they bloom. Fresh green leaves will grow up from beneath the flower stalks to remain until next spring.

Hepatica’s fuzzy flower stalks slowly unfurl to reveal the delicate flowers.

 

Hepatica leaves are three-lobed. The previous year’s leaves are often brownish-red or bronze and reminded earlier people of the human liver. (Hepatica is from the Greek word for liver.)

 

New green leaves grow beneath the flowers and will last all season.

In it’s natural setting, hepatica often grows under oak trees — that’s where I first spotted it peeping out among tattered brown leaves one warm April day at our cabin. (I purchased the hepatica in my garden at a local nursery.) It is a woodland wildflower that prefers full spring sun that becomes dappled sun as the trees leaf out. Two species are native to Minnesota — round-lobed and sharp-lobed — and are very similar in appearance. It’s also very well-behaved, so a gardener needn’t worry about hepatica overtaking the garden!

This week in the yard, besides the blooming hepatica, bloodroot leaves unfurled and increased in size as seed pods swelled. Many tiny native bees, and a not-so-tiny queen two-spotted bumble bee, pollinated the spring flowers. A wave of hermit thrushes ate insects and seeds in the backyard most of the week before continuing north to their nesting grounds. 

As the bloodroot blossoms (Sanguinaria canadensis) wilt, the leaves unfold and the seed pods begin to swell.

 

A queen bumble bee (Bombus bimaculatus) hovers above glory-of-the-snow (Chionodoxa luciliae) blossoms.

 

A hermit thrush (Catharus guttatus), one of the most ethereal songsters I’ve heard, rests on its journey to northern Minnesota and Canada.

Nesting sites are a hot commodity locally, too: A female mallard sits on her nest completely hidden in our neighbor’s daylily garden. Robins nest in arbor vitae behind the garage and cardinals nest in a neighbor’s small evergreen shrub. Each day, the cardinal pair visits our garden where the male gently feeds his mate. In a few weeks, the begging calls of this year’s first fledglings will fill the air. I look forward to seeing their plump, downy bodies following their parents around the garden!

 

 

Belted Kingfisher

The rusty band across this bird’s abdomen identifies it as a female belted kingfisher.

I first met the kingfisher on paper in a British literature class. The 19th-century poet Gerard Manley Hopkins, whose poems feature themes of nature and religion, included the kingfisher in his sonnet, “As Kingfishers Catch Fire.” Many of his poetic works include beautiful images of nature and humankind, each one reflecting the Creator by fully being itself. 

Several years later, I saw my first live belted kingfisher (Megaceryle alcyon) on the banks of the Snake River in east central Minnesota. A long, harsh rattle pierced the quiet river valley. Then, a flash of steely blue-gray sporting a shaggy crest swooped past as a belted kingfisher hunted for its dinner. Perching on a silver maple snag, it eyed the river intently for small fish, crayfish, mollusks, insects and other fresh-water delicacies. Soon, it hovered over the water, then plunged into the river headfirst and emerged with a small fish, scattering shards of sparkling droplets in the air.

A female belted kingfisher hovers over the river just before dropping into the water to catch a fish.

Belted kingfishers are similar in size to a blue jay — 11 to 14 inches in length — with a larger head, a dagger-shaped bill and a stocky body. The male and female both have blue-gray upper parts and a white breast with a blue-gray breast band. In addition, females have a rusty belly band that makes them easy to identify.

Notice the dark, pointed wing tips and blue-gray upper body coloration.

Unlike most perching birds, belted kingfishers nest in the ground. Usually both the female and male excavate a burrow high up in a riverbank, though some choose a gravel pit or similar area away from water. In northern regions, kingfishers mate once each spring. A clutch of 5-8 pure white eggs is typical. The eggs hatch after 24 days and the young are dependent on their parents for about six weeks. Though kingfishers in Canada and the far northern United States migrate south for the winter, they remain year round in most areas where they can find open water.

Kingfishers primarily eat small fish and crustaceans, but may also eat tadpoles, insects and berries if fish aren’t available. Belted kingfishers don’t have many predators, but are eaten by foxes, raccoons, snakes and hawks, such as Cooper’s and sharp-shinned. 

The kingfisher’s shaggy crest and long, pointed bill are identifying characteristics.

Worldwide, there are more than 110 species of kingfisher — and many of them are vividly colored, unlike their North American cousin. Most, such as the Philippine-dwarf kingfisher and the rufous-backed kingfisher are found in Asia. If Hopkins could have seen these handsome kingfishers, I think he’d have been even more delighted with the beauty of creation.

A Nuthatch Winter

This male white-breasted nuthatch (Sitta carolinensis) retrieved a seed from tree bark crevices. Notice the long, third toe used for balance.

The tiny, high-energy nuthatch is one of my favorite winter birds. Why the curious name “nuthatch”? “Hatch” was the Middle English word for hack or pound: nuthatches obtain much of their food by placing acorns and other nuts in bark crevices to hammer or hack open. They also store nuts and seeds under loose pieces of bark. Occasionally, I’ve seen red-breasted nuthatches with tiny twigs in their mouths and wondered if they were levering seeds out of a hiding place.

If you live near woods, or have trees in your yard, you’re likely to hear and see nuthatches. The white-breasted nuthatch is a year-round resident in Minnesota, and in most of the United States, Mexico and part of southern Canada.1 Its smaller cousin, the red-breasted nuthatch, is present in fewer numbers during the winter because most remain on their northern breeding grounds — unless there’s a shortage of spruce seeds, their primary food. In that case, they migrate in large numbers to the northern and eastern United States. This movement is called an irruption and it’s happening in 2018. (I saw my first red-breasted nuthatch of the season in our backyard on August 27.)

Similar in size to a house sparrow, the white-breasted nuthatch is a small bird with a big voice. I hear them call on the coldest winter days when most birds are silent. Its call is described as a nasal “yank-yank”. During the breeding season, the males also make a nasal “wha-wha-wha” song. They like deciduous trees, especially white oaks. Favorite foods include the nuts or seeds of oak, hickory, beech, maple, pine and spruce in the winter. They often come to suet and sunflower seed feeders, too. Insects and spiders are choice foods for the summer.

This red-breasted nuthatch (Sitta canadensis) carries a shaving of red pine bark, which it broke off of the tree. (Photograph used with permission.)

The tiny red-breasted nuthatch is present year-round at our cabin in east central Minnesota. Smaller than its white-breasted cousin, it’s about the size of a kinglet. Its song is also a nasal,“yank-yank,” however, it is higher pitched and has been compared to the tone of a toy tin horn. They frequently make fast, high-pitched squeaking calls. Red-breasteds favor coniferous forests, but can also be found in deciduous woods, parks and yards during a winter irruption. They eat the nuts of spruce and other conifers in the winter, and visit feeders for suet, sunflower seeds and peanuts. Insects and spiders are summer favorites.

Nuthatches are cavity nesters — red-breasteds often select dead aspens because the wood is soft and easy to excavate. White-breasteds nest in both deciduous and conifer trees — they’ll frequently use an old woodpecker nest, rather than dig out a new cavity. Both build a bed of grass and shredded bark, then line it with fur, feathers and other soft material. Each species raises one brood per year.

White oaks are a favorite food source of white-breasted nuthatches.

Both species sport blue-gray, black, and white coloration. However, the red-breasted nuthatch has a wide, black eyestripe, whereas the white-breasted shows mainly white around its eye. Upper parts on both nuthatches are blue-gray. All have a black crown except for the female white-breasted nuthatch, which has a blue-gray crown. Red-breasted nuthatches have rusty or rufous-colored underparts in contrast to the white-breasted’s mainly bright, white belly. Both species have a long rear toe that is used to grip the bark of trees. (Other climbers, such as woodpeckers and brown creepers, use their tail to support themselves when climbing a tree trunk.)

Red-breasted nuthatches are easily identified by their small size, rusty colored underparts and high-pitched calls.

 When you’re outside on winter days, listen for nuthatch “yank-yank-yank” calls and keep an eye on tree trunks for tiny blue-gray, black and white birds intently inspecting the bark. Since nuthatches often join small flocks of other winter birds, you might also see downy woodpeckers, brown creepers, chickadees and kinglets as an added bonus!

1North America has four species of nuthatch: the brown-headed and pygmy nuthatches, in addition to the white-breasted and red-breasted nuthatches. There are 25 nuthatch species worldwide.

Memories of Birds

I heard a flock of robins this morning, murmuring softly to each other in the silver maples and hackberries. A male cardinal, tucked into our arbor vitae, whistled his “what cheer” melody. They sang memories of my dear friend Cathy Borden, who died one year ago today.

Cathy loved birds and, as I held her hand in the silence of a January evening, a flock of robins filled the trees outside her window at Our Lady of Peace hospice. She would have loved seeing the robins. Though she wasn’t conscious, she stirred when I described their rusty breasts, black heads and charcoal backs, and how they picked berries in the twilight.

I spun tales of steamy summer afternoons when we hiked the woods and fields of Eagan, just a small city at that time; of goldfinches collecting thistledown to line their cozy nests, rose-breasted grosbeaks flashing their lovely badges along the hiking trail, and tiny common yellowthroats calling “wichity-wichity”in the willow scrubs.

The birds continue to awaken beautiful memories. One night last November, when the “moon of freezing over” shone full and close, a great-horned owl hooted from a spruce in our front yard. I eased open a window to listen to its soothing call and remembered evening bike rides with Cathy in the bluff country of southeastern Minnesota.  We rode wooded trails where barred owls with liquid black eyes watched us from tree limbs overhead, a hen turkey and her flock of fuzzy poults scurried about the path in front of us, and night herons croaked their calls at dusk.

Black-capped chickadees are companionable in the garden and the woods.

Perhaps it’s the tiny black-capped chickadee, Cathy’s favorite bird, that most often brings her to mind. One fine morning last spring after a night of thunderstorms, chickadees whistled to each other in my garden and the year’s first lily of the valley opened, covered in rain droplets. (She loved these flowers and tried to grow them for many years.) Cathy would have rejoiced in the antics of the chickadees, in the abundance of my lily of the valley garden, and in the beginning of a new day so fresh and lovely.

The Dove’s Call

A mated pair of mourning doves rests on a roof in the late afternoon sun.

The mourning dove’s (Zenaida macroura) call is a wild, haunting sound that complements the whistle of its wings. In mid-August, doves coo softly in the cool of early morning and in the sultry late-afternoon heat.

People react quite differently to the mourning dove’s call. A work colleague who grew up on a farm found the cooing to be so sad that her family removed any nests that were close to their farmhouse.

To our young son, who was born with a bilateral sensorineural hearing loss, discovering a dove’s sounds was a time of wonder. We returned home from work and daycare, one spring evening, and startled a dove in the backyard. The forceful whistle of its wings as it flew skyward was one of the first sounds he heard with his new hearing aids. He also loved their sweet call; if the doves quieted, he would spot one on the roof and say to it, “Don’t be shy little dove. Will you sing for me again, please?”

Mourning doves are warm buff to soft gray in color with black speckles on the wings.

I love the mourning dove’s call; I find it soothing and relaxing. It brings memories of steamy summer afternoons when I was growing up. We’d imitate their calls and try to spot them in the majestic elms that shaded Saint Paul’s streets. To find a dove’s nest woven in the boughs of a small spruce tree was pure delight. How innocent they looked with their large, dark eyes and bespeckled wings, nestled on a clutch of bright white eggs. How excited we were to experience this tiny bit of nature so close to home.

Early Spring Serenade

A male northern cardinal (Cardinalis cardinalis) sings from his springtime perch.

I like the silence of frosty mornings, but I also miss the music of birds during the winter. Most mornings for the past three weeks, our resident cardinal has greeted the sunrise — cloudy or clear — with song. At first he sang one short burst of bright song. Over the next week, it grew to several minutes of song at dawn and another round later in the morning. Basking in Tuesday’s sunshine and 70°, he sang many times during the day. Later that same day, a mourning dove cooed in a spruce tree, chickadees added their lovely two-note calls, and an American robin joined the serenade with its caroling. However, all went silent when a Cooper’s hawk sailed across the backyard and into my neighbor’s silver maple!

Why do birds sing more frequently in the spring? There’s still much to learn, but the thinking is that the increase in daylight triggers a bird’s thyroid-stimulating hormone (TSH). TSH steps up the production of sex hormones to prepare birds for the mating season. A big part of successful reproduction is attracting a mate and maintaining a breeding territory — birdsong plays a major role in both activities.

The four songsters mentioned above were year-round residents in the Twin Cities this past winter.  Soon migrants, such as warblers, red-winged blackbirds, catbirds and others will return to add their harmony to the chorus. In fact, I saw my first red-winged blackbird of the season perched on a cattail in a small pond yesterday. Regardless of its purpose, the return of beautiful birdsong is one of spring’s finest gifts.
