TO YELLOWSTONE NATIONAL PARK. 79 
three feet in height. The young were most of them so well grown at this time (July 15) that they 
would leave the nest at my approach and fly a few yards to another bush, where they would sit 
uttering the sharp cry that we hear from all young blackbirds at that age. When I approached 
the nests or young, flocks of a dozen or more old birds would fly over me uttering constantly cries 
of anxiety. 
About Camp Baker, they were very numerous; the flocks being so large as fairly to blacken the 
ground where they alighted. The birds were familiar enough and readily ventured up to our 
tent doors. 
CORVIDE. 
58, CORVUS CORAX, Linn. 
RAVEN. 
Rather common on the plains west of Carroll. 
59, CORVUS AMERICANUS, Aud. 
Crow. 
Extremely abundant on the streams flowing out of the Sweet Grass Ilills. They were breed- 
ing here in the tall undergrowth that fringed Box Elder and Armell’s Creek, and on the return 
march were seen in large flocks feeding on the dead buffalo that strewed the prairie. It is hardly 
necessary to remark that they were very tame, in striking coutrast to their eastern relatives. 
60. PICICORVUS COLUMBIANDS, (Wils.) Bp. 
CLARK'S Crow. 
I first noticed this species near Camp Baker, but it did not become very abundant until we 
reached the Yellowstone River on our road to the park. Its striking plumage and loud harsh 
voice makes this bird one of the most noticeable features of the animal life of this region. 
61. PICA MELANOLEUCA HUDSONICA, (Sub.) Coues. 
MAGPIE. 
Abundant everywhere in the mountains, and universally execrated by hunters and trappers on 
account of the injury it does in winter to the fresh-skins that are stretched out to dry, and the 
annoyance that it causes to their sore-backed animals. 
62. CYANURUS STELLERI MACROLOPHUS, (Baird) Allen. 
LONG-CRESTED JAY. 
Abundant from the Bridger Mountains through the Yellowstone Park. In habits, this species 
resembles most closely C. cristatus ; but its notes are quite different, being harsh and grating, more 
like those of P. columbianus. 
63. PERISOREUS CANADENSIS CAPITALIS, Baird. 
GRAY JAY. 
I found this species extremely abundant all through the mountains of the Yellowstone Park. 
They are noisy restless birds, continually passing to and fro among the branches of the pines with 
easy, graceful movements. They are at all times bold and even impudent, remaining in the trees, 
beneath which we encamped, and frequently descending to the ground within a few feet of some 
one of the party to pick up a piece of meat or a crumb of bread. When a morsel of food has been 
secured, itis taken to a low limb and there Icisurely broken up and devoured. 
This species is said to cause considerable annoyance to trappers by removing tho bait from 
their mink and marten traps.
