end of a branch bearing acorns, and pecking the acorn vigorously 

 for a minute would loosen it so that they could take it with their bills 

 I never saw either of these jays take an acorn from the ground, even 

 after they had all fallen, nor do I think they make any use of them, 

 as they nearly all spend the winter down in the valleys and at the 

 base of the foot-hills. 



TYRANNIDtE. 



42. Sayornis nigricans Bonap. Black Flycatcher. Rare 

 during August, became more numerous during September, and were 

 common in damp fields and along open streams until the middle of 

 November, where they would sit perched on a dead twig waiting for 

 their prey. Their habits and appearance remind one of the S.fus- 

 cus of the East. They had all migrated by the last of "November. 



43. Contopus virens var. Richardsoni Allen. Western 

 Wood Pewee. Not common. One specimen taken in September, 

 and a few others seen. 



44. Empidonax pusillus Cab. Little Flycatcher. One 

 specimen taken the last of September. The only one seen, although 

 probably this and the preceding are common earlier in the season. 



CAPRIMULGID^}. 



45. Antrostomus Nuttalli Cassin. Nuttall's Whip-poor- 

 will. Rare. Shot one specimen in a road after dark one night the 

 last week of October. 



TROCHILIDiE. 



46. Selasphorus Anna Bon. Anna Humming Bird. Com- 

 mon until the middle of October about flower gardens. I was shown 

 where a pair had built their nest for several seasons in some vines 

 growing over a porch. 



CUCULIDiE. 



47. Geococcyx californianus Baird. Chaparral Cock. 

 Was told of their rare occurrence. Did not hear of any being seen 

 for several years previous to my visit.
