Losses and Gains

Last August, near the end of the month, it was finally clear, cool, and free of the bothersome mosquitoes and gnats that make hiking in the hot, humid summer unpleasant. Still, I had persevered most days when it wasn’t storming.

On this August day, I chose to walk along Ten Springs Trail. That trail is on the edge of the 112 acres we purchased after it was badly logged back in 1991. On one side of the trail is our uncut forest, access road, Plummer’s Hollow stream and Laurel Ridge. On the other side on Sapsucker Ridge is the land that was logged and is now full of invasive shrubs and vines, most notably Japanese barberry, privet, multiflora rose, mile-a-minute, and Japanese stiltgrass.

I had thought the trail, which is one of the old logging roads, was wide enough to keep the invasives from crossing into the forest, but near a wetland on the logged side, I discovered that mile-a-minute had reached and crossed the trail, heading downslope into the forest. It and Japanese stiltgrass blanketed some areas, and the stiltgrass was spreading even in the deepest, darkest part of the deciduous forest. There was nothing to stop it; no native shrubs and saplings to keep it out. No jewelweed to smother it such as it does in the wetland inside our deer exclosure.

Multiflora rose

Eventually, I reached Turkey Bench and was saddened to see that the large red oak next to the bench had split near its base and fallen during one of the recent storms, creating another large opening in the forest that the invasives will rush to fill, if not stiltgrass or mile-a-minute, then Japanese barberry, privet and/or multiflora rose.

It seems as if much of what I record on my walks are losses, especially in this part of our property. Maybe losses are all I should expect now that I’m 80. Old age, I’m learning, is a time when you lose more and more and must be content with less and less. Still, I am grateful to be alive and reasonably able on this, my 57th wedding anniversary. And to sit on the bench and be serenaded by a pair of red-eyed vireos as they engage in countersinging, the second singer repeating each phrase exactly as the first chorister sings it.

But most of the songbirds that had filled the forest with birdsong from April until the end of July were silent. Already many migratory species were on their way south to the tropics for the fall and winter.

Eventually, I continued on Ten Springs Trail and found a couple native shrubs—a red-berried elder on the steep forest bank and a smooth blackhaw hidden behind a tree on the logged side. I passed the steam trickling down Bench Blind Hollow and then walked uphill and down, flipping off branches from several storms since I hadn’t been on that section of the trail all summer.

At last I reached Ten Springs Extension. It enters an uncut hollow and forest by a footpath built by our hunters 25 years ago. That path proved to be more of a challenge than I expected. The entrance was smothered in stiltgrass and was on a slant. I ended up carefully crawling through a small section of it.

The stone steps dug into the steep slope that leads to a streamlet were mostly gone so I eased my way down with the help of the stick I had used earlier to flip the branches off Ten Springs Trail.

Finally I crossed the stream bed and breathed a sigh of relief. Too soon, as it turned out. The trail the hunters had dug into the mountainside had eroded badly from the storms. Then as I inched my way along, I found myself blocked by an enormous red oak tree that had fallen recently. I crawled under the tree and then turned where the trail doubled back. There I was stopped by an even larger oak tree across the trail. I had to push my way through the upper half of the tree that had broken off downslope and then try to beat my way back up to the trail since it was totally covered with portions of the tree for several yards. To my relief I found and followed a faint deer track that led me back to the trail and down to the road.

I decided then that that would be the last time I would take Ten Springs Extension and that I would suggest we close the foot path. Closing it would protect the deep forest from invasives. Already one sunny spot had a circle of stiltgrass. And once the autumn leaves fell, the trail would be even more slippery and hazardous.

American beeches

I still had a mile to walk up our road, but this is my favorite part of our property. The steep road bank is covered with several dozen wildflower and native shrub species and the surrounding forest has many native trees such as basswood, cucumber magnolia, American beeches, and several oak species. At the end of August horsebalm, white wood asters, and blue-stemmed goldenrod were blooming. Spikenard, Indian cucumber-root, yellow mandarin, and jack-in-the-pulpit were fruiting. Many wild hydrangeas, red-berried elders and maple leaf viburnum shrubs grew in beds of several fern and clubmoss species. I also found healthy patches of partridgeberry in fruit.

Unfortunately, the “partridge” for which they are named—the ruffed grouse—is suffering from West Nile virus, and we have only found a couple drumming on our property in the last couple years instead of the ones that used to display on our road and flush with chicks at the edges of our forest and First Field.

Our hemlock trees that line the darkest part of our road have been affected by hemlock woolly adelgids but most, while thinning, are still holding on. Over half of our mountain laurel, that once blanketed Laurel Ridge, have died of a leaf fungus or blight, most likely Diaporthe kalmiae or possibly, according to a paper I can’t read in Japanese, Cercospora kalmiae, also called brown leaf spot. The mountain laurel used to provide excellent cover for wildlife, and wood thrushes and yellow-billed cuckoos favored it for nest-building. Unlike rhododendron and other native shrubs white-tailed deer eat, they only eat mountain laurel when they are starving. But they too used the mountain laurel for cover and shade.

Farther up the road I stopped to look at a large basswood tree stripped of its bark. It had fallen in a fierce storm earlier in the month and brought down a large red maple with it. Near the forks, a red oak 26 inches in diameter had come down in the same storm. But as I moved closer to look at the tree I spotted one of the loveliest wetland-loving wildflowers of August and September—a turtlehead.

And so the tree loss continued even as I approached our home and saw the immense black locust that had toppled in the storm, barely missing our house. I heard it crack while sitting in our sunroom and watched it fall.

Wood frog eggs

The increased winds and rains in Pennsylvania have turned our vernal pond into a permanent pond atop the oak and wild black cherry forest of Sapsucker Ridge. Not only are there now hundreds of wood frogs returning to it and two smaller ponds there each spring to court and lay masses of eggs, but the week before, as I approached the pond, I spotted a green frog, its large, bulbous eyes rimmed in orange and white, dark brown head and long nose, watching me from the algae-covered water.

Still, we’ve lost so much over the nearly 50 years we’ve lived here. Our last forest-dwelling American elm succumbed four years ago to the so-called “Dutch” elm disease which, in reality, came from an Asian fungus Ceratocystis ulmi. The elms’ seeds were favored by ruffed grouse, wood ducks, squirrels and opossums and every spring a porcupine nibbled on our elm’s buds and flowers.

Now most of our ash trees are dead or dying from still another pest from northeast Asia, the emerald ash borer Agrilus planipennis that was first discovered in Michigan near Detroit in the summer of 2002. Again, ashes also produced seeds that wildlife ate.

And because of our wet, sometimes too cold springs, for the second year in a row, our acorn crop was sparse. Even the scrub oaks on the powerline right-of-way had no acorns. Our wild grapes and wild black cherries again had no fruit. Even our blackberry crop was sparse.

On the other hand, our American bittersweet draped itself over four tall trees at the edge of First Field and was covered with orange berries, and our “pokeweed forest” above the spruce grove was laden with fruit. But it was still not enough to entice our fruit-loving birds to over winter. I can only hope for better wildlife crops this year.



The Yellow-throated Vireo

Late last June I sat next to our mountaintop vernal pond that has become a permanent pond the last couple wet years. For an instant, I glimpsed the white spectacles of a blue-headed vireo as it foraged on a large red maple tree across the pond. Then I heard a singing yellow-throated vireo, followed by the droning song of a red-eyed vireo.

I was used to hearing red-eyed and blue-headed vireos singing throughout our forest. But I was not as familiar with yellow-throated vireos. Our son Mark, who has keener ears than I, heard the same singing yellow-throated vireo at the ponds the following day and then another one singing outside the guesthouse day after day in late July and early August.

The vireo family, which includes 14 species in North America, is one of the few songbird families that is thriving. Blue-headed vireo numbers have doubled since the 1970s. Red-eyed vireo numbers have been increasing slowly but steadily from 1966 to 2014, and, here on our property during the various bird counts we’ve done, red-eyed vireos are always the most abundant songbird species, numbering 40 or more.

The yellow-throated vireo is more elusive than the blue-headed and red-eyed vireos. However, the Partners in Flight survey reported that they are common birds with a population that increased by 62% from 1970 to 2014. In Pennsylvania the Breeding Bird Survey recorded a 1.2% yearly increase since the 1960s with an estimated 48,000 yellow-throated males in our state.

Still, the blue-headed and red-eyed vireos have been studied far more than the yellow-throated vireo. Researchers have found that all three species nest in mature forests and spend their winters in a variety of forests mostly south of our borders.

The red-eyed travels the farthest to large forests in the Amazon basin. The blue-headed is a medium-distant migrant that spends its winters in shaded coffee plantations, rain forests, cloud forests, or coastal swamps from the southeastern United States coast, Mexico, and south through Central America as far as northern Honduras. Most yellow-throated vireos winter in Central and South America as far south as the mountains of western Colombia and northern Venezuela.

The yellow-throated vireo, sporting a bright yellow throat, breast, and eye-ring, is easily the flashiest of this mostly olive or gray-backed family of birds. In addition, it has a large bill, olive green upperparts with a contrasting gray rump, and bluish legs and feet. The yellow-throated and the blue-headed have white wing-bars, but the red-eyed vireo’s wings and back are a plain olive/brown.

All three species are easier to hear than see because they forage high in the trees, but telling their songs apart can be challenging. The blue-headed vireo has the highest pitched song with deliberate pauses in between, both slower than the red-eyed and with fewer notes per phrase, while the red-eyed vireo’s pitch is a little lower, droning, and monotonous, hence its nickname The Preacher Bird.

The yellow-throated vireo’s song is similar to but lower pitched than the blue-headed vireo. In the words of ornithologist Aretas A. Saunders, “The song is long continued, consisting of short phrases separated by pauses like the songs of the red-eyed and blue-headed vireos but the yellow-throated vireo’s song is slower, the pauses between phrases longer. The quality of the sound is rather reedy and less clear than the others [and] the phrases are usually slurred together.”

The yellow-throated vireo returns to Pennsylvania in late April or early May. Its arrival records at our central Pennsylvania mountain farm range from April 29 to May 13. This vireo is the most southern of the three species that breed on our property and is found from northcentral and southern New England south to the Gulf Coast and west to the eastern edge of the Great Plains.

It likes to breed in a mature deciduous forest and prefers large oaks and maples, although any tall tree will do. Back in the early twentieth century it was also a bird that nested in towns, suburban areas and cities as large as New York and Boston, but then they disappeared, possibly because of the heavy spraying of insecticides on the large shade trees to combat Dutch elm disease.

In Pennsylvania the habitat of the yellow-throateds consists of tall, old trees widely or closely spaced but without an understory, often near a water source. In our Ridge and Valley Province it builds its nest near a river or stream as high as 1300 feet above sea level. Other parts of the state where it breeds are in the northeast, northwest and southwest corners of the state, with low densities in the Piedmont and the High Plateau regions.

The male arrives first and looks for nest sites that he uses to tempt an arriving female. He sings and calls until a female comes close, and then stands over as many as three or four nest sites, each with a small amount of nest material, his head lowered as if he is building a nest. Sometimes he performs a pre-mating swaying display after he quivers his wings in response to the female’s wing-quivering.

Once they mate, she either accepts one of his nest sites or they may find still another. But unlike both the red-eyed and blue-headed vireos, which nest in shrubs or saplings no higher than 15 feet or as low as five feet from the ground, yellow-throated vireos build their nests in the crowns of the tallest trees, 20 to 50 feet above the ground, making this part of their lives difficult for researchers to observe.

It takes the pair about eight days to construct what ornithologist Arthur Cleveland Bent, in his Life Histories of North American Wagtails, Shrikes, Vireos, and Their Allies, described back in 1950 as “the handsomest nests of any of the vireos, …the whole body of the nest is almost completely covered with small bits of variously colored tree lichens, all held securely in place by numerous fine strands of spider silk, the deep cup, with its thick walls and incurving rim above it, is neatly lined with fine grass tops…” and attached to a forked limb.

Then Bent refers to the three to five, creamy or pinkish white eggs with a scattering of dark reddish to brown and black spots on their larger ends as “the handsomest and most heavily marked of any of the eggs of the vireos.”

Both parents incubate those eggs, although the female covers them at night and half the day while the male alternates with his mate during the day. They vigorously protest, chase and sometimes attack any jays or crows that venture near their nest, but the only predators ever recorded on yellow-throated vireos and their offspring are long-eared owls, Cooper’s hawks, and blue jays. Like other vireo species they also contend with brown-headed cowbird parasitism and usually accept those eggs with their own and feed the nestling cowbirds that compete with their nestling vireos. Researchers have found that in nests without cowbirds, there is at least three to four vireo young, but in those with cowbirds, there is less than one vireo nestling.

The yellow-throated vireo eggs hatch into naked young in 13 days and take a further 13 days to develop into feathered fledglings that have been tended and fed by both parents the usual insect and spider fare such as caterpillars, butterflies, moths, stinkbugs, scale insects, leaf hoppers, beetles, flies and bees, most of which they forage from the interior parts of leaves and branches in the middle and upper levels of the forest canopy.

The parents continue feeding the fledglings for at least two more weeks, but the second week each parent with half the young, go their separate ways, although they may reunite at a later period for a short time. For instance, our son, Mark, last July 24, found a family group of six yellow-throated vireos in an area of young black locusts between the spruce grove and the pond area.

But eventually they go their separate ways in late August, beginning their slow migration south. Our latest date is October 17, but more normally they leave around the middle of September, which is true for most of the commonwealth. During migration they use open woodlands and brushy woodland understory and edges and are not observed as often in the fall as they are in the spring, even though both sexes still display their bright yellow throats.

Some researchers have evidence to suggest that they may use a more eastern route during fall than spring migration and migrate in a southeasterly direction. That may explain why they are rarely seen during fall migration in Pennsylvania and then no more than one or two birds in any one place. Usually, they forage singly with mixed-species flocks of wood-warblers, chickadees, titmice, and other small songbirds.

We can only hope that the yellow-throated vireo and all its relatives continue to thrive in their nesting grounds.


The Cut-Throat Bird

On a hot, humid morning in late June, I climbed to the top of Sapsucker Ridge. As I followed the trail, I was serenaded by the singing of a hooded warbler, a black-throated green warbler, red-eyed vireos, and eastern towhees.

Suddenly, I heard harsh, loud, and repeated calling from an agitated brown and white rose-breasted grosbeak perched on a small tree beside the trail. She emitted what I later learned was the grosbeaks’ “squawk” alarm call. And squawk she did even as I continued on my way. Then she was joined by a second bird and they squawked back and forth. It was the nattily dressed black and white male sporting his rosy-red, V-shaped breast patch. He had flown in and perched high in a tree above the female. Not wanting to disturb them further, I walked on and still they called to each other, this time using their common metallic “chink” call.

I assumed that the pair was defending nestlings and that I had passed close to them since rose-breasted grosbeaks place their nests 10 to 15 feet up in the fork of a tree sometimes at the edge of a road and that section of our Sapsuker Ridge Trail is actually an old logging road.

Rose-breasted grosbeaks were familiar to early settlers since the first ones were collected before 1760 in Louisiana, presumably during migration because they don’t breed there. After several genus name changes, they were finally placed in the Pheuticus genus in 1850 which they share with the closely-related black-headed grosbeak of western North America. Pheuticus means “shy” or “to flee” in Greek and their species’ name ludoviciana is French for Louisiana. Their common name is “cut-throats” because of their rosy breasts.

These birds breed from southern Canada, the upper Mississippi Valley and the northeastern United States south through the Appalachian Mountains to northeastern Georgia. Here in Pennsylvania both atlasing breeding projects found that rose-breasted grosbeaks were widely distributed throughout much of the commonwealth but were not abundant in any one section. Because they were rarely found below 820 feet, they were more common across the northern third of Pennsylvania.

Their numbers also fluctuate from decade to decade. For instance, during Breeding Bird Surveys through the 1980s their numbers were high but decreased during the 1990s. And the Second Atlas of Breeding Birds in Pennsylvania, early in this century, found that rose-breasted grosbeaks were uncommon in the southern Ridge and Valley Province. Nicholas C. Bolgiano, who authored the account in the second atlas, suggested that because rose-breasted grosbeaks prefer to nest in young woodlands but not in highly fragmented forests, they may be finding it more difficult to find their preferred nesting habitats as our forests age.

On the other hand, older reports of nesting rose-breasted grosbeaks in Pennsylvania indicate a wide variety of nesting habitats, i.e. young to second-growth deciduous or mixed woodlands, thickets at the edge of roads or bordering streams or swamps, old orchards, shrubby fields, parks and gardens.

I did a short study of where I’ve seen rose-breasted grosbeaks on our mountaintop property in this century and discovered, to my surprise, almost everywhere including the building of a nest at the edge of the overgrown Far Field observed by one of our hunter friends—Tim Tyler—during spring gobbler season on May 12, 2007. Other areas were along Sapsucker Ridge Trail, in or near our three-acre deer exclosure, the Far Field Road, Greenbrier and Bird Count trails, and on Dogwood Knoll—all places above 820 feet. The only wet areas were a lower section of the exclosure and another encompassing a portion of Greenbrier Trail.

Rose-breasted grosbeaks return to Pennsylvania anywhere from the fourth week in April to the fourth week in May, although peak migration is the middle of May according to McWilliams and Brauning in The Birds of Pennsylvania. However, my earliest record for their return in this century is April 29, 2007, and most reliably the first week in May. By the second week in May, during International Migratory Bird Day, we always find rose-breasted grosbeaks, most notably the 12 that we counted in 2006 and the 7 in 2007.

I more often hear their brilliant songs, described by Roger Tory Peterson as robins that have taken voice lessons, than see rose-breasted grosbeaks since the males stay hidden in leafy treetops. But back in May 8, 2018, I encountered a continual chorus of rose-breasted grosbeaks, and after much persistence managed to get a good look at a male. Both sexes sing, but it is the male that first attracts a female by singing. When she approaches him, he rebuffs her for a day or two and then accepts her.

They appear to be monogamous during the nesting season and share in the building of a nest, which takes four to eight days, despite its flimsy construction. Composed of dried sticks and twigs, grasses, weed stems, decayed leaves or straw and lined with smaller twigs, rootlets or hair, if a person stands beneath the nest, the one to five, pale green to blue eggs spotted with reddish-brown or purple, can be seen through the nest lining. The grosbeaks choose any native tree or shrub species that hides the nest with dense foliage especially maple, birch, willow, or common alder, and in Cook Forest State Park, Hal Harrison, author of A Field Guide to Birds’ Nests, found a nest in rhododendron that was lined entirely with hemlock twigs. He concluded that “Apparently any small tree or shrub will do so long as it provides sufficient shelter.”

Rose-breasted grosbeaks also share nest egg incubation duties, the male relieving the female for one-third of the daylight hours, while the female is the sole night incubator. Both sing even on the nest, especially the male, which would seem to signal to nest predators, especially blue jays, common grackles, raccoons, red and gray squirrels, that there are eggs for the taking. It is likely, though, that the singing is to warn off other grosbeaks, male and female, from their immediate territory.

Most eggs in Pennsylvania nests are laid anywhere from May 15 until June 10 and incubation lasts 11 to 14 days. Once the eggs hatch, the parents share brooding the nestlings and keeping them fed, mostly with insect larvae and other insects, especially beetles (75%), and wild fruit, such as mulberries and June berries, as well as weed seeds—smartweed, pigweed, foxtail, and milkweed.  The adults like sunflower seeds at birdfeeders in spring and summer, peas, wheat, oats, tree flowers and buds and even cultivated fruits.

Our native shrub, the red-berried elder, which has berries in early June, is popular with rose-breasted grosbeaks for both nesting sites and food for their young. Back in June 10, 2007, when I approached a large red-berried elder on Ten Springs Trail, a male rose-breasted grosbeak landed on the shrub. I watched while he quickly consumed all the ripe berries on two umbels before flying off, giving me one of my closest and best looks at this beautiful bird.

It takes nestlings 9 to 12 days to mature enough to fledge, but the parents care for them another three weeks, and they stay together as a family until they migrate anywhere from late August to the second week in October in Pennsylvania. They also try to keep themselves and their grown offspring safe from Cooper’s hawks, sharp-shinned hawks, northern harriers, eastern screech-owls and short-eared owls, all of which prey on the adults and mature young.

During migration, rose-breasted grosbeaks, young and old, eat almost exclusively fruit. They overwinter in Central and South America, mainly in midland and highland forests and half-open habitats, as high as 11,000 feet in Colombia. In some areas the males are popular cage birds.

Although the overall population of rose-breasted grosbeaks has shown a slow decline from 1966 to 2015 according to the North American Breeding Bird Survey, they are not listed as Threatened or Endangered in any part of their range. Here in Pennsylvania the statewide population is estimated at 210,000 singing birds. So these handsome birds—glorious to look at and to hear—should be in the commonwealth for decades to come if we provide the kinds of habitats they favor.

A Sedentary May

After days of fighting my arthritic left foot and back last May, I gave up wandering our trails during my favorite time of year. Instead, I spent hours watching and listening for birds from our veranda.

The veranda side of the house from the First Field

The veranda side of our house faces a roughly-cut patch of grass, the driveway, our 37-acre overgrown First Field and our large bank barn. Beyond the field a wooded Sapsucker Ridge rises. The trees on the veranda side are mostly black walnuts along with a young tulip tree our son, Dave, planted several years ago off one corner of the veranda and century-old lilac shrubs at the other corner.

From the veranda I can also see our backyard lined with a thick growth of forsythia. Beyond is our garage at the end of our road. Our home is perched atop a bluff so our front yard drops off steeply to an uncut old lawn, a small stream and wetland area. Dave also transplanted several trees from our surrounding forest—white pine, red oak, and more tulip trees–to eventually replace century-old black locust trees as they topple and split during frequent wind storms.

Our yard on the other side of the house from the veranda slopes down through a couple dying ash trees and a heavy undergrowth of wildflowers and grasses to a flat, grassy area before it reaches the Laurel Ridge forest. In other words, our house sits in the midst of field and wooded edge habitat, and although my hearing is not as sharp as it used to be, I can still hear forest and field birds singing and calling while sitting on the veranda.

For instance, on International Migratory Bird Day, I heard and counted 30 species during a couple morning hours on the veranda even though it was cool and foggy. Most notable were the loud “wheeps” of the first great-crested flycatcher of the season. This cavity-nesting flycatcher thrives in forested openings with tall, dead trees where it builds its snakeskin-lined nest.

Nearly all the birds that return in May breed on our mountain. The blue-gray gnatcatchers build their nest on a black locust branch. The gray catbirds favor the forsythia hedge and the lilacs, flying back and forth in front of the veranda, living their busy, noisy lives, and the northern cardinals tuck their nest in the one remaining multi-flora rose bush beside our driveway.

Most lively of all are the Carolina wrens. After nearly a week of rain, I managed to walk up to our two-car, cement-block garage where an eastern phoebe family always nests on one of the ledges inside the garage. The phoebe female sat tightly on a nest in the back of the garage while Carolina wrens were feeding nestlings on the ledge beside our car. Both parents had caterpillars in their bills and scolded loudly when I walked into the garage. I retreated but checked again later when one Carolina wren scuttled out from beneath the car and flew outside protesting my presence.

That was on May 18. The following evening we had a huge storm as wind swept rain over the veranda. Then we noticed two Carolina wren fledglings clinging by their feet to the living room/veranda window screen, while a third one huddled on the floor below. When Bruce and I went outside to see if we could help them, the adults appeared, and off they all flew into the storm around the house to the back porch. This turned out to be the garage ledge family. After that they acted as if they belonged on the veranda and the back porch and often scolded us when we appeared.

One afternoon they flew on to the veranda table and vocally protested when Bruce sat on his usual seat close by. Near dusk they came chattering into an old phoebe nest on top of the veranda. We counted the three fledglings as they settled in for the night and were serenaded by their parents in the lilac shrub. Without doubt, Carolina wrens are the most charming and entertaining of any songbirds we have here.

Early in May Virginia bluebells bloomed in our backyard as well as a wide swath of ajuga in our lawn. Both blue-colored flowers attracted returning ruby-throated hummingbirds. One warm afternoon I pulled on a red sweatshirt, went outside to join Bruce on the veranda, and told him I was going to attract a hummingbird. Almost immediately a hummingbird buzzed me as Bruce watched. Our daughter-in-law Paola, down in the guesthouse, faithfully hung three hummingbird feeders from the front porch and spent hours watching those feisty birds compete for food.

Then there was the hen turkey. I’m not certain she’s the same one we see every spring, but she always seems to have a hidden nest somewhere in First Field or maybe in the woods at the base of Sapsucker Ridge. Last spring she first appeared walking down our driveway on the morning of May 6 when I stepped outside. After that we saw her numerous times. One afternoon I spotted her on the barn bank while I sat on the veranda. She walked up close to the edge of the driveway in First Field and then paraded across the middle of the field. The next day I saw her on the Laurel Ridge side of the house in the flat area. But with all her walking about we have never seen her with a family. I wondered if she had lost her young because of the incessant rain and storms or predators or perhaps she was infertile.

Still another mystery was what happened to our bluebird couple. Early in the spring we had put up a new bluebird nesting box on a power pole beside an open area near the garage. The bluebirds occupied it, but the box was far enough away from the veranda that I only watched it from afar.

The same day the hen turkey first walked down the driveway, I saw a tree swallow, his deep blue back reflected in the sunlight, swoop through the air near the bluebird box as if he wanted that nest box for himself. But the male bluebird perched above the box in a watchful stance and at last the tree swallow gave up, flew the length of First Field toward the spruce grove and disappeared.

I was so engaged with all the birds I was watching, that it was several weeks before I realized that I hadn’t seen the bluebirds for a while. On a clear day in late May I took a short walk across the lawn and up the driveway, displacing three small rabbits eating grass in the median strip. That’s when I noticed a strange figure blocking the entrance to the bluebird box and went over to have a look. It was the desiccated tail of the female bluebird. I called Bruce to help me open the nest box and we discovered the dried-up female bluebird hanging over her complete nest but there was no sign of chicks or eggs. I wondered if the male had been unable to find enough food for her during the many rain storms or if he had starved or been killed by a predator.

As I sat on the veranda day after day, I noticed that the suite of singing birds changed from hour to hour. And almost every day there were new arrivals. The same day the bluebird held off the tree swallow, the first indigo bunting sang from the topmost branch of a medium-sized walnut tree in the middle of First Field. On May 18 in mid-afternoon I heard the first eastern wood-pewee singing his lazy “pee-a-wee.” The next day sitting in my study with the window open, I heard the blasting song of the returning Baltimore oriole. Two days later, a cerulean warbler sang in the backyard walnut trees. That was the last bird species to return.

I listened to my favorite songsters, the wood thrushes, every morning and evening and a whip-poor-will at 5:00 a.m. and 9:00 p.m. as he circled the house calling. There were frequent song contests between male scarlet tanagers up in the walnut trees. And the randy chipping sparrows often mated on black walnut branches.

On a beautiful Memorial Day I spent from dawn to dusk outside listening to and watching our yard and field birds. Two surprise birds were the hooded warbler that landed on top of a nearby veranda chair and the yellow warbler singing down near the old apple tree at the edge of First Field beside the driveway. Another bonus at 7:06 p.m. was a barred owl that called from Sapsucker Ridge.

All in all, I had had a memorable Memorial Day and sedentary May in which I recorded 45 bird species from common ravens and turkey vultures to a Cooper’s hawk and common yellowthroats.
