The sparrows, warblers and hummingbirds followed 

 the course of the divide, or nearly so, but a number of 

 species went directly toward the Sacramento Valley. 

 Among the latter were two species of blackbirds, a few 

 ravens and white geese. California jays, kingfishers 

 and several species of small birds, or rather individuals 

 of these, were noted and were thought to be on their way 

 down the west slope. 



The first rain of the season fell on September fourth. 

 The third and the fourth were cooler and cloudy when 

 Say's chipmunk and the yellow-bellied marmot were 

 evidently preparing for the storm by carrying bedding 

 into their burrows. No marmots were seen after the 

 rain of the fourth, and hummingbirds were rarely seen 

 afterwa,rd. No tyrant flycatchers were seen after the 

 ninth. 



On the tenth Anthus pensilvanicus and Otocoris alpes- 

 tris strigata arrived from the north. 



Zonotrichia leucophrys intermedia came two days later, 

 but Z. coronata did not arrive until the twenty-fifth, 

 when there was rain and snow. 



Helminthophila celatu lutescens, H. ruficupilla (jutturu- 

 lis, Geothlypis macgillivrayi, Spizella breweri and Pipilo 

 chlorurus were seen on September twenty-fourth, but not 

 afterward. Zonotrichia leucophrys was last seen on the 

 twenty-eighth, when Passerella iliacu unalaschcensis was 

 first seen. By October tenth the migration was about 

 over, a migration characterized mostly by short flights; 

 made leisurely, often by single individuals acting inde- 

 pendently. No night migrations were detected. 



At Murphys, altitude about 2,300 feet, Mr. J. J. Sny- 

 der noted the female Louisiana tanager as very comnion; 

 the male very rare on August 24, 1885, and that Bullock's 

 oriole and the black-headed grosbeak were also very rare. 

 Cliff swallows were not seen after August 18.
