126 EXPLORATIONS AND SURVEYS WEST OF IOOTH MERIDIAN. 



l')6. Contopus borealis, (Sw.) Olive-sided Flycatcher. 



Common at Apache, Ariz, in August, keeping chiefly in the neigh- 

 borhood of the river. Also noticed further south on the Gila. 



Upper mandible black, lower light-brown; legs and feet black. 



107. Contopus pertinaxj Cab. Coues's Flycatcher; Mexican Olive-sided 



Flycatcher. 



Apparently a very rare species. I met with it but on a single occa- 

 sion, in the heavy pine-woods near Apache, Ariz. While riding along, 

 I was attracted by certain loud, harsh, screaming notes, and, dismount- 

 ing, after much trouble and dodging among the trees, I succeeded in 

 getting a sight at the authors, and found that a pair of old birds were 

 feeding several young, the latter being fully fledged, and not distin- 

 guishable in colors at the distance from the old. As a result of two 

 shots I obtained both the old birds, and found them to be this species. 

 The plumage was very much worn and bleached. 



Iris brown; bill above black, below bright-yellow; legs and feet black. 



108. Contopus virens (L.), var. richardsonii, Sw. Western Wood-Pewee. 



An especially abundant species at Inscription Rock, N. Mex., where 

 both old and young were seen July 23 among the cedars. Common along 

 our route in Eastern Arizona. Arboreal in its habits at all seasons. 



Iris brown; bill black; lower mandible yellow; tip brown; feet black. 



109. Empidonax pusillus, (Sw.) Little Flycatcher. 



Seen occasionally on the streams about Apache in August. 

 Bill black above, pale-brown beneath.
