TURDUS MIGRATORIUS. 

 The Robin. 



The robin is, apparently, nowhere on the Pacific coast so abundant as in the eastern States, 

 but is generally distributed over all the region west of the Rocky mountains. While traversing 

 the Sacramento valley we saw none of these birds, meeting with the first only when we had 

 been some weeks out, on Canoe creek, a tributary of Pit river. Subsequently we saw them fre- 

 quently and most abundantly in the Willamette valley, near the Columbia. 



TURDUS N^VIUS. 

 Oregon Robin. 



This robin-like bird we found associated in flocks, and having much the habits of T. migrato- 

 rius, in the Cascade mountains, and on the hills bordering the Willamette valley, in Oregon, 

 in October, 1855. 



ICTERIA LONGICAUDA? 

 The Yellow-breasted Chat. 



This pretty bird is found rather abundantly in the Sacramento valley, about San Francisco, 

 and south of that city, in California, where it remains through the winter. In summer it 

 ranges to the Columbia, and northward. 



TYRANNULA SAYA. 



Say's Fly Catcher. 



Not uncommon throughout California and Oregon. 



TYRANNULA NIGRICANS. 

 Black Fly Catcher. 

 Common in northern California. Specimens were also obtained in the Umpqua valley, Oregon. 



TYRANNULA CINERASCENS. 



Common about San Francisco, California, where it is probably frequently mistaken for T. 

 crinita. 



BOMBYCILLA CAROLINENSIS. 



The Cedar Bird. 



We saw the cedar bird on only one or two occasions, in small numbers, in the pine forests of 

 Oregon.
