第45章

Family cares rest lightly on the cuckoos. The nest of both species is a ramshackle affair -- a mere bundle of twigs and sticks without a rim to keep the eggs from rolling from the bush, where they rest, to the ground. Unlike their European relative, they have the decency to rear their own young and not impose this heavy task on others; but the cuckoos on both sides of the Atlantic are most erratic and irregular in their nesting habits. The overworked mother-bird often lays an egg while brooding over its nearly hatched companion, and the two or three half-grown fledglings already in the nest may roll the large greenish eggs out upon the ground, while both parents are off searching for food to quiet their noisy clamorings. Such distracting mismanagement in the nursery is enough to make a homeless wanderer of any father. It is the mother-bird that tumbles to the ground at your approach from sheer fright; feigns lameness, trails her wings as she tries to entice you away from the nest. The male bird shows far less concern; a no more devoted father, we fear, than he is a lover. It is said he changes his mate every year.

Altogether, the cuckoo is a very different sort of bird from what our fancy pictured. The little Swiss creatures of wood that fly out of the doors of clocks and call out the bed-hour to sleepy children, are chiefly responsible for the false impressions of our mature years. The American bird does not repeat its name, and its harsh, grating "kuk, kuk," does not remotely suggest the sweet voice of its European relative.

BANK SWALLOW (Clivicola riparia) Swallow family Called also: SAND MARTIN; SAND SWALLOWLength -- 5 to 5.5 inches. About an inch shorter than the English sparrow, but apparently much larger because of its wide wing-spread.

Male and Female -- Grayish brown or clay-colored above. Upper wings and tail darkest. Below, white, with brownish band across chest. Tail, which is rounded and more nearly square than the other swallows, is obscurely edged with white.

Range -- Throughout North America south of Hudson Bay.

Migrations -- April. October. Summer resident.

Where a brook cuts its way through a sand bank to reach the sea is an ideal nesting ground for a colony of sand martins. The face of the high bank shows a number of clean, round holes indiscriminately bored into the sand, as if the place had just received a cannonading; but instead of war an atmosphere of peace pervades the place in midsummer, when you are most likely to visit it.

Now that the young ones have flown from their nests that your arm can barely reach through the tunnelled sand or clay, there can be little harm in examining the feathers dropped from gulls, ducks, and other water-birds with which the grassy home is lined.

The bank swallow's nest, like the kingfisher's, which it resembles, is his home as well. There he rests when tired of flying about in pursuit of insect food. Perhaps a bird that has been resting in one of the tunnels, startled by your innocent housebreaking, will fly out across your face, near enough for you to see how unlike the other swallows he is: smaller, plainer, and with none of their glinting steel-blues and buffs about him. With strong, swift flight he rejoins his fellows, wheeling, skimming, darting through the air above you, and uttering his characteristic "giggling twitter," that is one of the cheeriest noises heard along the beach. In early October vast numbers of these swallows may be seen in loose flocks along the Jersey coast, slowly making their way South. Clouds of them miles in extent are recorded.

Closely associated with the sand martin is the Rough-winged Swallow (Stelgidopteryx serripennis), not to be distinguished from its companion on the wing, but easily recognized by its dull-gray throat and the absence of the brown breast-band when seen at close range.

CEDAR BIRD (Ampelis cedrorum) Waxwing family Called also: CEDAR WAXWING [AOU 1998]; CHERRY-BIRD; CANADA ROBIN; RECOLLETLength -- 7 to 8 inches. About one-fifth smaller than the robin.

Male -- Upper parts rich grayish brown, with plum-colored tints showing through the brown on crest, throat, breast, wings, and tail. A velvety-black line on forehead runs through the eye and back of crest. Chin black; crest conspicuous; breast lighter than the back, and shading into yellow underneath. Wings have quill-shafts of secondaries elongated, and with brilliant vermilion tips like drops of sealing-wax, rarely seen on tail quills, which have yellow bands across the end.

Female -- With duller plumage, smaller crest, and narrower tail-band.

Range -- North America, from northern British provinces to Central America in winter.

Migrations -- A roving resident, without fixed seasons for migrating.

As the cedar birds travel about in great flocks that quickly exhaust their special food in a neighborhood, they necessarily lead a nomadic life -- here to-day, gone to-morrow -- and, like the Arabs, they "silently steal away." It is surprising how very little noise so great a company of these birds make at any time. That is because they are singularly gentle and refined; soft of voice, as they are of color, their plumage suggesting a fine Japanese water-color painting on silk, with its beautiful sheen and exquisitely blended tints.

One listens in vain for a song; only a lisping "Twee-twee-ze," or "a dreary whisper," as Minot calls their low-toned communications with each other, reaches our ears from their high perches in the cedar trees, where they sit, almost motionless hours at a time, digesting the enormous quantities of juniper and whortleberries, wild cherries, worms, and insects upon which they have gormandized.

Nuttall gives the cedar birds credit for excessive politeness to each other.

He says he has often seen them passing a worm from one to another down a whole row of beaks and back again before it was finally eaten.
