MYIARCHUS CINERASCENS. 533 



more pairs of this ftimiliar eastern bird had their abode among the large 

 cotton-wood trees near our camp; in fact, this species seemed to be no more 

 rare in that locahty than the T. rrrticalls, which, however, was itself far 

 from common. On the eastern border of the Great Basin it was more 

 abundant, being qnite as numerous in the Salt Lake Valley as the T. verti- 

 cnJis, both frequently nesting in the same grove.

Tliis species was apparently not abundant anywhere, being probably 

 more so in the Sacramento Valley than in any locality eastward of tlie 

 Sierra Nevada. It Avas not noticed in the vicinity of Sacramento City, in 

 June, but among the oaks of the plains toward the foot-hills of the Sierras 

 it was connnon early in July. A few were observed among the cotton- 

 woods of the lower Truckee in July and August, and it was also a not infre- 

 quent summer-resident in the canons of the Ruby Mountains, where it Avas 

 most often observed perched upon a gnarled cedar or mountain-mahogony 

 overhanging the top of a rocky gorge or high clitf. It was very rare in 

 Parley's Park. 



Resembling its eastern relative, the Great Crested Flycatcher (il/. criiii- 

 tius-), in its general habits, its notes, however, are weaker, and do not possess 

 in so great a degree the strikingly wild character so marked in the vehe- 

 ment whistlings of that species.
