known as v&T.pusillus. Specimens from the two regions are indistinguishable. The 
habits of the bird in the two regions are quite identical. The bird is an abundant one 
in Southern California, and especially so in the swampy thickets about Los Angeles. 
A nearly-completed nest of this bird, which I found June 17, was placed iu a crotch 
of a swinging grape-vine, and its structure was unusually neat and firm for a Flycatcher. 
A curious departure from the usual method of nidification has just come to my notice. 
Mr. Allen, of-, discovered the nest of this species, with eggs, built in the hollow 
of a tree. The parent was secured, and its identity thus firmly established.

100. Empidonax obscurns, (Swains.).—Wright’s Flycatcher. 
I saw but a few of this species in the Sierras, near Mount Whitney, in September. 
One specimen obtained here was in such immature plumage that I think it had been 
reared in the neighborhood.

101. Empidonax hammondi, (Xantus).—Hammond’s Flycatcher. 
I could find no evidence that this Flycatcher breeds in Southern California, though 
I am by no means positive that the deep mountains do not afford it a summer home. 
Dr. Cooper’s account of its method of nidification refers with but little doubt to the 
var. pusillus. 
After September, the species became a common one in the mountains. It remains 
till into October, but finally retires farther south.
