more intelligently return to the birds. Among the more common 
birds that one meets with along the streams of the western edge of 
the Great Plains are such familiar eastern species as the kingbird, 
eatbird, brown thrush, and the Baltimore and orchard orioles, all 
of which appear to find their western limit in Colorado at the base 
of the Rocky Mountains, though further north some of them range 
nearly'or quite across the continent. Of other species characteris- 
tie of the western edge of the Plains are many that occur not 
only eastwardly to the Atlantic, but also westward to the Pacific, 
as the robin, yellow warbler (Dendreca estiva) the cliff, barn, 
white-bellied and rough-winged swallows, the meadow lark, house 
Wren, yellow-breasted chat, nipping, field, Lincoln’s, and bay- 
winged sparrows, the black-capped titmouse, red-winged black- 
bird, red-headed woodpecker, Carolina dove, kingfisher, yellow bird 
or goldfinch, marsh and sparrow hawks, the killdeer plover and 
Spotted sandpiper, nearly all of which were seen more or less fre- 
quently throughout most of our journey in the mountains, as well as 
at their eastern base. The loggerhead shrike was occasionally seen 
as were also such common species of the Plains as the lark finch, 
lark bunting, black-headed grosbeak, mountain plover and Arkan- 
sas flycatcher, all except the loggerhead being exclusively western 
Species. Say’s flycatcher was common near the mountains; 
the western solitary vireo (Vireo plumbeus Coues), the west- 
wood pewee, an Empidonax, and the warbling vireo were 
all frequent, and were met with occasionally in the mountains up 
to about ten thousand feet. The horned lark was abundant at all 
favorable localities up to about the same altitude, above which no 
‘alities such as it usually frequents were met with. The moun- 
tain mockingbird was not only present here, but was also observed 
m * considerably greater altitude. Of the western forest birds, 
Audubon’s warbler, the violet-green swallow, the arctic bluebird, 
the arctic towhe, the green-tailed or Blanding’s finch (Pipilo chloru- 
mus) the western indigobird or lazuli finch, Lewis’s woodpecker, 
Woodhouse’s and the great-crested jays, Brewer’s blackbird, the 
magpie and raven, were all more or less common, but far more 
Pa the foothills than on the plains.
