food and uttering only a sliarji eliivp occasionally. They are then in tlie 

 dull iilumage of the female, and tlie males do not ol)tain tlieir riclier hues 

 and black breast until IVIareli or April. According to Hceruuinn, they 

 winter as far north as Sacramento, and some, I think, remain near the 

 CoUunbia Ifiver throughout mild winters. Aliout i\Iay 1st they aU seem 

 to retire towards the north, and I have seen none even in tlie Coast ]\Ioun- 

 tains, south of San Francisco, after that month, but they begin to appear 

 again in September. 



Tlieir song resembles tliat of the D. cvdivo, and is heard chiefly in their 

 summer resorts towards the north. 1 obtained newly fledged young at Lake 

 Tahoe in September, and they pro])ably raise their broods throughout the 

 higher Sierra Nevada. 



The nest is believed liy Nuttall to be built in the tall coniferous trees, 

 but has not yet been discovered. 



This species does not returii to the latitude of Santa Cruz (37°, and at 

 the sea level) until the end of September, but some remain there all winter; 

 and about ]\Iarch 2(Jth the males, ra])idly changing their plain winter 

 livery for the gayer lines of summer, favor us with a few faint notes bel'ore 

 their departure north, the song being much like that of the D. a-siiva in 

 character. They disappear about April loth.
