EVENING GliOSBEAK 419 



No notes were uttered during this display. When this male began his 

 movements another of the male birds quitted his own mate and moved 

 toward the performer; but no real belligerency was manifested. 



In the fall and winter months the evening grosbeaks sometimes assemble 

 in flocks numbering many indi\'iduals and these bands may stray do^vn 

 into the foothill country. Flocks were noted in Yosemite Valley in Sep- 

 tember, 1920, and one large flock was seen there (3ctober 2, 1920 (C. W. 

 Michael, MS). Large flocks were reported by Mr. Donald D. McLean 

 from Smith Creek, east of Coulterville, in October, 1916. Specimens were 

 obtained at that place on October 11 and December 18 of that year. During 

 the summer season the grosbeaks are sometimes seen in small bands of 

 a dozen individuals or less. It may be that even during the nesting 

 season the adults assemble in flocks for feeding. The flock formation is 

 always loose and the flight of the individuals is strongly undulating, each 

 rising and falling quite independently of its companions. Indeed the 

 band seen at Artist Point looked like nothing so much as 'giant' gold- 

 finches, both their coloration and manner of flight contributing to this 

 impression. 



We obtained only one hint relative to the nesting of the evening gros- 

 beak. At Hazel Green, on May 14, 1919, a female was seen flying through 

 the scattering trees of a meadow, carrying a long twig in her bill. She 

 was about 25 feet above the ground, and was followed by a male. Both 

 were soon lost to sight as thev made off into the forest of firs.

Field characters. — Size large for a sparro^v, only slightly le?s than that of Robin; 

 tail long appearing. Plumage in general, incliuling wings and tail, dark gray, %vithout 

 any white markings. Males have head, breast, and rump pinkish red; females and 

 immature birds have top of head and rump dull yellow. Voice : Call note, a loud clear 

 icoit-leek, repeated. 



Occurrence. — Sparse resident in Hudsonian Zone on west slope of Sierra Nevada. 

 Observed on ridge at 9000 feet four miles southwest of Dark Hole, July 2, 1915, and 

 in Ten Lakes basin, October 8 and 11, 1915. Frequents coniferous trees of its zone. 



The two large grosbeaks of the higher part of the Sierra Nevada are 

 by no means as abundant as the Black-headed Grosbeak is at the lower 

 levels, and the California Pine Grosbeak is decidedly the rarer of the two 

 mountain species. According to the authors' knowledge the present species 

 does not, in the Yosemite region, occur below the Hudsonian Zone even 

 in midwinter. 



Being a bird of predominantly gray coloration and medium size, the 

 California Pine Grosbeak is not likely to be confused with any other species 

 in the region, save perhaps the Townsend Solitaire. The pine grosbeak
