110. Empidonax flaviventris Bd., var. difficilis, Bd. Western Yellow- 

 bellied Flycatcher. 



As in summer, seems to prefer the narrow canons and secluded locali- 

 ties. Common, and generally distributed. 



111. Empidonax obscurus, (Sw.) Wright's Flycatcher. 



A common and in the fall a pretty generally-distributed species, fre- 

 quenting not only the copses and thickets of the streams, but also the 

 groves of oaks and other deciduous trees. Quick and energetic in its 

 motions. In this respect in marked contrast to the succeeding species, 

 which it resembles somewhat in its appearance. 



112. Empidonax kammondii, De Vesey. Hammond's Flycatcher. 



Perhaps the most common of the Empidonaces. From Apache south- 

 ward, seen all along the route, preferring generally the oak-groves, from 

 the low limbs of which trees it sallied forth after insects. Has the same 

 rather listless habits as noticed in the summer, with less dash and spirit 

 than any of the small flycatchers.
