great numbers to the small fresb water ponds in the vicinity of Fort Steilacoom, where they 
remain during the summer and rear their young. This proverbially noisy, restless bird retains 
all the peculiar habits on the Pacific that so distinguish it in other localities.—S. 
The killdeer plover is a common summer resident in the interior of the Territory, arriving 
at Puget Sound early in May, and remaining until October, raising its young during the season. 
I have never seen this species on the coast.—C. 
AEGIAL1TIS MONTANUS, (Towns.) Cassin.

Aegialtes montanus, Bon. List. 1838. 
Aegialitis montanus. Baibd and Cassin, Gen. Rep. Birds, 693. 
Sp. Ch. —Forehead, stripe over the eye, and entire under parts, white, generally tinged with dull yellowish and ashy on the 
breast. Another band of black in front above the white band ; back of the neck and sides dull brownish fulvous ; other 
upper parts ashy brown, usually with many feathers edged and tipped with fulvous or rufous; upper tail coverts lighter. 
Quills dark brown, with their shafts white, tail brown with a wide subterminal band of brownish black and tipped with white. 
Shorter primaries with a white space on their outer webs, forming a patch of white on the wing ; under wing coverts and 
axillary feathers pure silky white. Bill black, legs yellow. Younger, without the black hand in front, and with the white 
band tinged with dull yellow, entire upper parts with the feather edged and tipped with dull ashy rufous. Total length, 
about 9 inches; wing, 6 ; tail, 3 inches. 
Sab —Western North America. 
I obtained a specimen of this bird, sbot in a “prairie dog town” on Milk river, Nebraska, and 
have reason to believe that it is found in southern California and New Mexico. Not observed 
by me in Washington or Oregon. Perhaps it may be found in summer in the interior of 
southern Oregon towards Utah. The habits of the bird I obtained in Nebraska seem somewhat 
to resemble those of the golden plover in apparently preferring dry open ground. 
I also saw a stuffed specimen in the collection of F. Gruber, San Francisco.—S.
