Whip-poor-will's Song Tugs At A Memory


Nostalgia sweeps over me when I hear the call of the whip-poor-will as he passes through the Central Savannah River Area in spring migration.

This wisp-of-the-night is a summer resident of the North Georgia mountains where I lived as a child. Consequently, his continuous calls were one of the first "bird voices" I could recognize. These denizens of the night came into the edge of our yard as the sun splotched glades of the surrounding woodlands were overtaken by the spooky twilight of dusk.

Although many people have heard the songs of this ghost of the night, few people have ever seen the author. These birds sleep all day on dead leaves and other debris on the forest floor, their mottled coloration protecting them from enemies.

I used to sit with my dad on the steps of a stone wall in the deepening dusk to listen to the whip's calling as he did almost every night throughout the summer. Suddenly, there the bird was on an almost bare oak branch where he began his incessant "whip-poor-will, whip-poor-will, whip-poor-will". Then he dropped to a sandy spot in the road where he continued his calling for a hundred times or more. Reluctantly, I had to go to bed most nights with the whip still calling.

This spectral bird belongs to the Goatsuck family. Believing these birds sucked milk from goats during the night, centuries ago Europeans gave them the ill-named moniker of goatsucker. These birds did and do fly around goats and cattle at twilight, but it is to catch insects bothering the animals rather than the whip's love of milk.

This fellow has an enormous mouth, bordered above by long, stiff bristles which act as a net in catching insects, their only diet.

Measuring around ten inches from his short, dark bill to the short, rounded tail, the whip's overall plumage mimics the color of dead leaves of the forest floor. He wears a narrow white necklace around his throat. In flight, white tail feathers flash out. The female appears all brown. The large, black pair of button eyes, typical of nocturnal birds and mammals, is the easiest field mark to attract attention.

No attempt at nest building is made. The two eggs, buff colored with gray or light lavender splotches, are laid on a litter of dead leaves where the flickering light of the woodland tends to give them protection. The incubation period is around twenty days. During incubation, the female sits with her eyes closed, the better to avoid detection.

The nestlings match the dead leaves on which they are hatched. Their down is soft and silky, shading in color from cinnamon on the back to pinkish cinnamon on the crown and abdomen.

The whip is a common summer resident of both north Georgia and the upstate of South Carolina. It is now thought to breed along the Edisto River in Aiken County and in the Lake Thurmond area. It has been heard calling in midsummer, a good indication that it is expanding its breeding range southward. It winters along the Gulf and Florida coasts. Some of the more daring will go on to the Islands for their winter respite.

Don't Confuse A Loggerhead With A Mocker


We haven't seen him in our yard for several years, but on a sunny warm May day, he arrived. He sits on a dead limb of a dogwood tree and surveys the comings and goings of the large insects and butterflies fluttering by. I make myself comfortable to watch for the catch, but it doesn't materialize. Evidently, beetle or butterfly fingers don't whet his appetite, or the warm sun has made him too lazy to make the effort for such a small prize.

Slightly smaller than a robin, the loggerhead shrike has a big rounded head, thick neck and an all black, hawk-like bill and hook-like claws.

Having the weak feet of song birds, the shrike kills its prey with his strong bill, shaking, twisting and choking it until it is dead. Small birds, shrews, small rodents, grasshoppers and other large insects are some of its favorite catches. Shrikes hunt only by day and have remarkable eyesight, comparable to that of hawks, eagles and falcons. They are the only truly predatory songbirds in that they consistently prey on vertebrate animals.

The shrike gets its nickname "butcher bird" from the habit of hanging its prey on thorny trees, barbs of wire fence, or wedging them into the crotches of limbs. The head of the victim is up, the body hanging suspended, much like a butcher hangs a leg of lamb or a side of beef from a hook in his shop.

These situations are used as pantries to store food for future use as well as a "dish" for his present meal. The thorny branch, his plate, holds the prey while he eats it. There are scientists who say shrikes don't return to eat the impaled food. There are others who say it does occasionally return for its stored food. I wouldn't know, but when I'm out on walks I see dried insects, a mouse or bird hanging on thorns, indicating the prey has been there for awhile.

Light gray covers the back and head of the shrike. A black mask covers the eyes. Black wings with a white patch, white throat and dirty white breast complete his attire. He blends well with his surroundings.

The only bird that could be confused with the shrike in our area is the mockingbird. Though both are black and white and gray birds, the shades and tones of the colors differ, the shrike's being much lighter. The shrike is a chunkier bird than the mocker and his head is larger with a thicker neck. The black, gray and white of the shrike are distinctly defined. They don't blend as they do in the mocker's plumage.

Breeding from Florida northward to southern Canada and westward to Louisiana, the loggerhead is a common resident of the Central Savannah River Area. He builds a bulky nest of twigs, leaves and grasses in a thorny bush or dense tree from eight to twenty feet above ground. Usually, a clutch of four to seven dull white to grayish or creamy white eggs is laid. They are thickly and evenly spotted and blotched with dull browns and light lavender.

The loggerhead is a poor songster. About the best he can do is a series of squeaky whistles, strangling gurgles and high-pitched pipings, though sometimes he might burst into harsh warble-like notes.

Common nicknames are French mockingbird, butcher bird and cotton bird, from the habit of using cotton in his nest.

Noisy Outcast Pretty But Annoying


In every family there's a black sheep, usually. The yellow-breasted chat is that dude in the warbler family.

When you think of a warbler, you think of a small songster dressed in olive-greens, yellows, grays, blues and black and whites. The chat fits into the family as far as colors are concerned, but there his qualifications end.

His song, if you can call it a song, unlike that of any other warbler, is loud and fractious. Not only is the song unusual but the manner of singing is different. He flies from one bush to another while getting his garrulous message across. All the other little warblers' songs are soft and pleasing.

He is a full two inches larger than most warblers. He has a long tail like a mocker, a bill that is larger, heavier and more curved than the smaller warblers and his wings are shorter and rounded.

He's a handsome guy. He wears this year's fashionable olive-green on his back with a yellow shirt. His colors glisten in the golden sunlight. The white strip over his eye and his size distinguish him from the small yellow-throated vireo.

He prefers brushy habitats for his hangouts, the better to hide, for he is more often heard than seen.

The eccentric, ludicrous, almost clownish behavior is one of the chat's most outstanding characteristics. He hides in dense thickets and from this secluded place he sends out "bizarre noises", whistling, chuckling, barking, mewing, scolding and swearing. He gurgles, laughs, chatters, squeaks and cackles.

But wait, when the females arrive from the tropics his language changes. He finds some elevated perch and there pours out what melody he can muster. Then, pitching himself into the air . . . straight up . . . with wings fluttering and legs dangling limply like a Raggedy Ann doll, he lets fall from his yellow throat a wild, rich, rapturous love song. While he's courting he leaves off name calling.

Measuring 1 and 1/2 inches from the stout, arched bill to the long, rounded tail, this largest of all warblers is the good ole boy of the bird world. He's here now, joking and cat-calling and generally interrupting the sweet songs of other birds.

The chat claims a characteristic of the mockingbird and that is singing all night on moonlit nights, but the chat adds dark nights also to deliver his repertoire.

One chat observer says the olive-clad bird on her premises usually starts singing at 10:30 in the evening and keeps up his "noise" all through the night. The next morning she serves breakfast, accompanied by his squeaks and squawks. She serves the noon meal. The shrieking goes on and on. Sometime in the late afternoon the songster stops, apparently to rest up for his next performance at 10:30 that night.

Becoming involved with keeping four hungry nestlings satisfied, he quietens down. He's so quiet you might think he's left his tangled haunts, but he's still skulking around.

By late August, however, he heads south and calm once again reigns in thickets and tangles across the countryside.

Small Effort Brings A Treat


Walking in the yard, I heard distinctly the feeding cries of young birds. Because the cries seemed to be near I searched every shrub and tree for a nest.

Several species of birds were in and about the yard but not being able to find a nest, the birds' cries haunted me.

The next day I sat down on the terrace with glasses and followed each bird that came into view. It was not long before I picked up a tufted titmouse with food in its beak. It alighted in a nearby pine tree and quickly disappeared without my seeing where it vanished. Again, I heard the feeding cries of nestlings.

I examined the tree and found no cavity. To my amazement a few seconds later the bird popped out of an old squirrel's nest. The rodent's nest was situated on a large branch approximately four inches in diameter and about two-thirds out on a limb from the trunk of the tree. It was placed among three small branches that grew out from the larger one. The opening of the squirrel's nest was directly in line with the large branch. Each time the bird came with dinner for the nestlings it alighted on the large branch near the opening, then tip-toeing into the hole, it went down into the cavity.

On leaving the nest, it first stuck its head out of the opening and looked around as if checking to see if all were safe. Then it came up out of the cavity and flew away.

The large-eyed, black-eyed, tufted titmouse is a permanent resident in the Central Savannah River Area. It has a gray pointed crest, which it can raise or lower at will, gray back, off-white breast and belly with rusty-red sides and short, rounded wings.

Usual nesting sites of the titmouse are old woodpecker holes or other cavities. Because the bill is short and stout without a chisel, it is unable to excavate its own cavity, unless the wood is very rotted, and much search for a deserted cavity or openings in posts, dead trees, or bird boxes.

A pair of titmice visit our yard each summer and raise a family in cavities of old trees or in bird boxes placed near the wooded lot.

Titmice are fairly early nesters and usually only one brood is raised in a season. By the time the young are on the wing and are finding their own beetles, caterpillars and wasps, having perfected their "peto, peto, peto" song, you will be unable to tell the young from the mother and father when they visit the sunflower feeders in your yard this fall.

After fledging, all the families of titmice in the neighborhood get together as one big party for the rest of the summer until they join mixed flocks of chickadees, gnatcatchers and white-throated sparrows that roam the woods during fall and winter.

But, if you feed them well, you might expect a lively troupe of titmice in your yard during the cold, gray days of winter.

What a treat for such small effort!
