at on the earth rather than expose themselves by flight。 Sometimes they run nimbly over the frozen ground to escape an intruder； but flying they reserve as a last resort。 When the visitor has passed they quickly return to their dinner。 If they were content to eat less ravenously and remain slender； fewer victims might be slaughtered annually to tickle the palates of the epicure。 It is a mystery what they find to fatten upon when snow covers the frozen ground。 Even in the severe midwinter storms they will not seek the protection of the woods； but always prefer sandy dunes with their scrubby undergrowth or open meadow lands。 Occasionally a small flock wanders toward the farms to pick up seeds that are blown from the hayricks or scattered about the barn…yard by overfed domestic fowls。
The Prairie Horned Lark （Otocoris alpestris praticola） is similar to the preceding； but a trifle smaller and paler； with a white instead of a yellow streak above the eye； the throat yellowish or entirely white instead of sulphur…yellow； and other minor differences。 It has a far more southerly range； confined to northern portions of the United States from the Mississippi eastward。 Once a distinctly prairie bird； it now roams wherever large stretches of open country that suit its purposes are cleared in the East； and remains resident。 This species also sings in midair on the wing； but its song is a crude； half…inarticulate affair； barely audible from a height of two hundred feet。
AMERICAN PIPIT （Anthus pensilvanicus） Wagtail family
Called also： TITLARK； BROWN OR RED LARK
Length 6。38 to 7 inches。 About the size of a sparrow。 Male and Female Upper parts brown； wings and tail dark olive…brown； the wing coverts tipped with buff or whitish； and ends of outer tail feathers white； conspicuous in flight。 White or yellowish eye…ring； and line above the eye。 Underneath light buff brown； with spots on breast and sides； the under parts being washed with brown of various shades。 Feet brown。 Hind toe…nail as long as or longer than the toe。 Range North America at large。 Winters south of Virginia to Mexico and beyond。 Migrations April。 October or November。 Common in the United States； chiefly during the migrations。
The color of this bird varies slightly with age and sex； the under parts ranging from white through pale rosy brown to a reddish tinge； but at any season； and under all circumstances； the pipit is a distinctly brown bird； resembling the water thrushes not in plumage only； but in the comical tail waggings and jerkings that alone are sufficient to identify it。 However the books may tell us the bird is a wagtail； it certainly possesses two strong characteristics of true larks： it is a walker； delighting in walking or running； never hopping over the ground； and it has the angelic habit of singing as it flies。
During the migrations the pipits are abundant in salt marshes or open stretches of country inland； that； with lark…like preference； they choose for feeding grounds。 When flushed； all the flock rise together with uncertain flight； hovering and wheeling about the place； calling down dee…dee； dee…dee above your head until you have passed on your way； then promptly returning to the spot from whence they were disturbed。 Along the roadsides and pastures； where two or three birds are frequently seen together； they are too often mistaken for the vesper sparrows because of their similar size and coloring； but their easy； graceful walk should distinguish them at once from the hopping sparrow。 They often run to get ahead of some one in the lane； but rarely fly if they can help it； and then scarcely higher than a fence…rail。 Early in summer they are off for the mountains in the north。 Labrador is their chosen nesting ground； and they are said to place their grassy nest； lined with lichens or moss； flat upon the ground still another lark trait。 Their eggs are chocolate…brown scratched with black。
WHIPPOORWILL （Antrostomus vociferus） Goatsucker family
＇Called also： WHIP…POOR…WILL； AOU 1998＇
Length 9 to 10 inches。 About the size of the robin。 Apparently much larger； because of its long wings and wide wingspread。 Male A long…winged bird； mottled all over with reddish brown； grayish black； and dusky white； numerous bristles fringing the large mouth。 A narrow white band across the upper breast。 Tail quills on the end and under side white。 Female Similar to male； except that the tail is dusky in color where that of the male is white。 Band on breast buff instead of white。 Range United States； to the plains。 Not common near the sea。 Migrations Late April to middle of September。 Summer resident。
The whippoorwill； because of its nocturnal habits and plaintive note； is invested with a reputation for occult power which inspires a chilling awe among superstitious people； and leads them insanely to attribute to it an evil influence； but it is a harmless； useful night prowler； flying low and catching enormous numbers of hurtful insects； always the winged varieties； in its peculiar fly…trap mouth。
It loves the rocky； solitary woods； where it sleeps all day； but it is seldom seen； even after painstaking search； because of its dull； mottled markings conforming so nearly to rocks and dry leaves； and because of its unusual habit of stretching itself length…wise on a tree branch or ledge； where it is easily confounded with a patch of lichen； and thus overlooked。 If by accident one happens upon a sleeping bird； it suddenly rouses and flies away； making no more sound than a passing butterfly a curious and uncanny silence that is quite remarkable。 When the sun goes down and as the gloaming deepens； the bird's activity increases； and it begins its nightly duties； emitting from time to time； like a sentry on his post or a watchman of the night； the doleful call which has given the bird its common name。 It
〃Mourns unseen； and ceaseless sings Ever a note of wail and woe；〃
that our Dutch ancestors interpreted as 〃Quote…kerr…kee；〃 and so called it。 They had a tradition that no frost ever appeared after the bird had been heard calling in the spring； and that it wisely left for warmer skies before frost came in the autumn。 Prudent bird； never caught napping！
It is erratic in its choice of habitations； even when rock and solitude seem suited to its taste。 Very rarely is this odd bird found close to the seashore； and in the Hudson River valley it keeps a half mile or more back from the river。
The eggs； generally two in number； are creamy white； dashed with dark and olive spots； and laid on the ground on dry leaves； or in a little hollow in rock or stump never in a nest built with loving care。 But in extenuation of such carelessness it may be said that； if disturbed or threatened； the mother shows no lack of maternal instinct； and removes her young； carrying them in her beak as a cat conveys her kittens to secure shelter。
NIGHTHAWK （Chordeiles virginianus） Goatsucker family

Length 9 to 10 inches。 About the same length as the robin； but apparently much long
