Makes fok jpield identification — Moderate size, two black bands across 

 chest, white collar around hind neck, white bar across wing, tawny rump patch, 

 and white tipped, black banded tail. The shrill call. Mil-dee, is distinctive. 

 This is our only shore bird with two black bands across breast. 



Voice — ^Usually a loud, high-pitched, two-syllabled Mil-deer, or Mil-dee, 

 rapidly enunciated; occasionally, as when flushed excitedly from ground, it 

 becomes Mil-dee, dee, dee, dee-ey ; also when running along ground in advance of 

 an observer, a softer de-e-e-e-e-et is sometimes uttered. 



Nest — On ground, usually near water, in grass or on bare, sandy or pebbly 

 area; a shallow depression with or without a sparse lining of short, dry grass 

 blades, weed stalks, pebbles, or bits of hardened earth. 



Eggs — Usually 4, pear-shaped, measuring in inches, 1.46 to 1.56 by 1.02 to 

 1.10 (in millimeters, 37.0 to 39.5 by 26.0 to 28.0), and averaging 1.51 by 1.06 

 (38.2 by 26.8) ; ground color light clay or dull cream, with bold markings of 

 dark brown, black and dull lavender (four sets, 15 eggs, from California). 



General distribution — North and South America. Breeds from central 

 British Columbia, southern Mackenzie, central Keewatin, and central Quebec, 

 south throughout the whole United States, and in Mexico to latitude of south- 

 ern Lower California. Winters from New Jersey, Indiana, Texas, Arizona and 

 central California south to Venezuela and Peru in South America (modified 

 from A. O. V. Check-list, 1910, p. 128). 



Distribution in California — Abundant summer visitant to suitable localities 

 throughout the state, chiefly in the lowlands, but ranging locally up high in 

 the mountains, even to 8,600 feet altitude (as on Tuolumne Meadows, Yosemite 

 National Park). Winters in the valleys west of the Sierras from about the 

 latitude of San Francisco southward, and, more rarely, east of the Sierras from 

 Owens Valley southward. 



The Killdeer is one of the commonest, most widely distributed, and 

 perhaps the best known of all our shore birds. In the East it has been 

 considerably reduced in numbers, but in the "West it has held its 

 place and numbers despite the encroachments of civilization. In the 

 northern half of California the species is chiefly a summer sojourner,
