the extreme dryness of the atmosphere, the want of shelter from 
the intense rays of the sun—an intensity one can hardly appre- 
ciate until he has passed a few summer days far out on the Plains 
— «nd the dry, heated powerful winds so constant here, few would 
be surprised at the faded, bleached and worn plumage that char- 
acterizes the birds of the Plains. It is more noticeable of course 
in those that do not frequent the timber, though more or less 
apparent in all. Here the common “house” wren is bleached 
and faded, forming the so-called Troglodytes Parkmanni, differing 
from the T. aédon of the east only in this particular. The meadow 
and horned larks look singularly “ weather worn,” the former 
constituting the Sturnella neglecta of authors, and the latter the 
uda rufa of Audubon, in which the yellow almost entirely 
disappears from the forehead, throat and lores, fading to white. 
night-hawk becomes much lighter and paler, forming the race 
known as Chordeiles Henryi; Peucea estivalis wears a very faded 
aspect, and forms the so called P. Cassinii. The yellow-winged 
Sparrow becomes equally faded and changed, and the killdeer 
_ Plover shows a similar paling of the colors, which is also notice- 
able in birds as brightly colored as the Baltimore oriole. The 
color of the mountain plover is in similar harmony with the mid- 
Summer gray tint of the plains. In respect to the Baltimore, we 
find here a well marked race, characterized by the middle coverts 
Of the wing being white instead of bright yellow, and by having 
much more white on edges of the secondaries. The bill is also 
Slenderer and relatively longer. The Leavenworth specimens I 
find are, in respect to color, about half way between the Fort Hays 
type and the common form of the Eastern States.
