February in Berkeley, 



by the general rufous coloring, both on 

 the back and the side of the breast. 

 The male bird has a throat-patch of 

 coppery red, while the throat of Anna's 

 hummer is of an amethyst hue. Al- 

 though the rufous hummer is so easily 

 distinguished from our larger resident 

 species, it is practically impossible to 

 tell it from Allen's hummer. The only 

 infallible mark of distinction is the 

 character of the tail-feathers. In the 

 rufous hummer the two feathers next to 

 the central one are broad and deeply 

 nicked, these same feathers being 

 plainly pointed in Allen's, hummer. 

 The outermost pair in the latter species 

 is extremely narrow, while in the former 

 bird these feathers are fully double in 

 width. In general the rufous coloring 

 is less intense in Allen's hummer, and 

 the bird is a trifle smaller in size. 



As we pass the live-oaks, a party of 



California jays salute us with their 



merry squawking call, the blithesome 



Audubon's warbler, ever in motion and
