CHARADRITDA’-— CHARADRIINA: PLOVER. 601 
lariy variegated ; several inner pairs like the back, insensibly blackening towards ends, then 
lightening again, and usually with rusty tips ; lateral ones gaining more and more of the bright 
color of the rump, with more definite black subterminal bars, and pure white tips ; outermost 
pair mostly white, with the rufous shade, and several broken black bars. The effect of all this 
variegation is very striking when the parts are displayed in flight. Bill black; eye black, 
with a bright ring around it; legs pale. Length 9.00-10.00; extent 20.00; wing 6.00; tail 3.50- 
4.00, proportionally longer and more rounded than usual in this genus; bill 0.80; tibiae bare 
0.80; tarsus 1.40; middle toe and claw 1.12. $9, young: The black bands replaced by gray ; 
upper parts duller and more grayish ; and when quite young the feathers of the upper parts 
spotted with rusty brown; rump pale, markings of tail incomplete; but the birds speedily 
acquire a plumage like that of the adults. Downy young: Above, gray with a ruddy tinge ; 
a ring round top of head, aring round neck, 
a stripe down back, and another on each 
side of the colored area, black ; collar round 
back of neck, forehead, and ends of wing- 
tufts, white; tail-tuft and bill black — queer 
little creatures, readily recognized. N. Arn. 
at large, very abundant, breeding anywhere ; 
abounds in the West. Not gregarious nor 
maritime ; extensively but somewhat ir- 
regularly migratory. A very noisy bird — 
the curious name is derived from its shrill 
two-syllabled whistle, like kil-deer! kil- 
deer! Nest anywhere in the grass or 
shingle near water. Eggs 4, about 1.50 x 
1.12, of usual wading-bird shape ; ground 
varying from drab through clay-color to ie ’

creamy, marked in endless variation with 
blackish-brown. Kildeers’ eggs and those of Tringoides macularius do excellent duty in boys’ 
and amateurs’ cabinets for those of most small waders.

ashy-gray (dry-sand color), the feathers with still paler edges, the shade tending to fulvous on

stripe, not prolonged behind eye, not meeting its fellow over base of bill, where the white fore- 
head comes down to the bill. A black half-ring on the foreneck, not completed around back 
of neck. White of throat passing around hind-neck as a slight collar. Under parts, excepting 
the black bar, entirely white. Primaries blackish, bleaching towards bases on inner webs, the

than head. Young: Similar; no black on vertex or lore; a broad band of the color of the
