Indeed; if we cannot study our bird afield; the next best place to become acquainted with it is in the pages of the English poets。 But due allowance must be made for differences of temperament。 Our cuckoo is scarcely a 〃merry harbinger〃; his talents; such as they are; certainly are not musical。 However; the guttural cluck is not discordant; and the black…billed species; at least; has a soft; mellow voice that seems to indicate an embryonic songster。

〃K…k…k…k; kow…kow…ow…kow…ow!〃 is a familiar sound in many localities; but the large。 slim;; pigeon…shaped; brownish…olive bird that makes it; securely hidden in the low trees and shrubs that are its haunts; is not often personally known。 Catching a glimpse only of the grayish…white under parts from where we stand looking up into the tree at it; it is quite impossible to tell the bird from the yellow…billed species。 When; as it flies about; we are able to note the red circles about its eyes; its black bill; and the absence of black tail feathers; with their white 〃thumb…nail〃 spots; and see no bright cinnamon feathers on the wings (the yellow…billed specie's distinguishing marks); we can at last claim acquaintance with the black…billed cuckoo。 Our two common cuckoos are so nearly alike that they are constantly confused in the popular mind and very often in the writings of ornithologists。 At first glance the birds look alike。 Their haunts are almost identical; their habits are the same; and; as they usually keep well out of sight; it is not surprising if confusion arise。

Neither cuckoo knows how to build a proper home; a bunch of sticks dropped carelessly into the bush; where the hapless babies that emerge from the greenish eggs will not have far to fall when they tumble out of bed; as they must inevitably do; may by courtesy only be called a nest。 The cuckoo is said to suck the eggs of other birds; but; surely; such vice is only the rarest dissipation。 Insects of many kinds and 〃tent caterpillars〃 chiefly are their chosen food。


YELLOW…BILLED CUCKOO (Coccyzus americanus) Cuckoo family

Called also: RAIN CROW

Length  11 to 12 inches。 About one…fifth longer than the robin。 Male and Female  Grayish brown above; with bronze tint in   feathers。 Underneath grayish white。 Bill; which is as tong as   head; arched; acute; and more robust than the black…billed   species; and with lower mandible yellow。 Wings washed with   bright cinnamon…brown。 Tail has outer quills black;   conspicuously marked with white thumb…nail spots。 Female larger。 Range  North America; from Mexico to Labrador。 Most common in temperate climates。 Rare on Pacific slope。 Migrations  Late April。 September。 Summer resident。

〃Kak; k…kuh; k…kuk; k…kuk!〃 like an exaggerated tree…toad's rattle; is a sound that; when first heard; makes you rush out of doors instantly to 〃name〃 the bird。 Look for him in the depths of the tall shrubbery or low trees; near running water; if there is any in the neighborhood; and if you are more fortunate than most people; you will presently become acquainted with the yellow…billed cuckoo。 When seen perching at a little distance; his large; slim body; grayish brown; with olive tints above and whitish below; can scarcely be distinguished from that of the black…billed species。 It is not until you get close enough to note the yellow bill; reddish…brown wings; and black tail feathers with their white 〃thumb…nail〃 marks; that you know which cuckoo you are watching。 In repose the bird looks dazed or stupid; but as it darts about among the trees after insects; noiselessly slipping to another one that promises better results; and hopping along the limbs after performing a series of beautiful evolutions among the branches as it hunts for its favorite 〃tent caterpillars;〃 it appears what it really is: an unusually active; graceful; intelligent bird。

A solitary wanderer; nevertheless one cuckoo in an apple orchard is worth a hundred robins in ridding it of caterpillars and inch…worms; for it delights in killing many more of these than it can possibly eat。 In the autumn it varies its diet with minute fresh…water shellfish from the swamp and lake。 Mulberries; that look so like caterpillars the bird possibly likes them on that account; it devours wholesale。

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 SWALLOW

Length  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; RECOLLET

Length  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 littl
