PASSERES— TYKANNIDAE— EMPIDONAX IIAMMONDI.

only heard in the breeding season, is never possessed by the Least, Fly- 

 catcher, whose corresponding utterance, — for it can hardly be said to be 

 a song, though it is probably intended as such, — is che-bec, clie-bec ; the 

 two efforts having not the slightest resemblance. 



Hammond's Flycatcher was seen by us on several occasions in Utah, 

 though only in fall. About Denver, Colo., I did not find it ; but in the 

 mountains of Southern Colorado it is perhaps as numerous as any of the 

 Empidonaces, while in Arizona it appears to be the most so, particularly 

 in fall, when in migrating it extends over much of the country, showing a 

 special predilection for the oak groves. Its habits are essentially the same 

 as in summer, though it is now almost silent.
