20 EXPLOKAT10NS AND SURVEYS WEST OF 100TH MERIDIAN. 



COBVID^E. 



Corvus corax, L., var. carnworus, Bartr. American Raven. 



The most common and characteristic bird of Nevada and Utah ; par- 

 ticularly numerous in the vicinity of cattle-ranges. It is variable in its 

 disposition, at times very shy and at others permitting the closest 

 approach. Not generally found above the plains and foot-hills. 



Corvus americamis, Aud. Common Crow. 



Comparatively rare; met with only at Provo, where a number were 

 seen at different times. Said by the settlers to have appeared within a 

 few years. 



Picicorvus columMamts, (Wils.) Clark's Crow. 



Not observed until September 8, when a pair were noticed at Otter 

 Creek, Middle Utah. From this time until the middle of October it 

 was seen almost daily, singly and in flocks. It was invariably on the 

 wing, flying from side to side of the mountains, generally to the numer- 

 ous cedars, and uttering its peculiar notes, which consist of a succession 

 of short rattling cries. Owing to its singular uneasiness, almost akin 

 to shyness, none were secured. Its flight is undulating and its habits 

 much resemble those of the woodpeckers (Picidcc). 



Pica melanoleuca, Y., var. hudsonica Sab. Magpie. 



Numerous in mountains and plains of Eastern Nevada and Utah. 

 Shy and difficult of approach. Its voice is singularly flexible, and 

 capable of producing a variety of sounds, from the guttural chuckle to 

 the softest whistle. Eesideut throughout the year. 



Cyanurus stelleri, (Gm.), var. macrolopJia Bd. Long-crested Jay. 



Apparently confined to mountains and canons. Specimens taken at 

 Provo in Julv and November. Winters.
