The Birds of Wyoming. 101 



459. Contopus borealis (Swains.). 

 Olive-sided Flycatcher. 



Summer resident ; but very little is known of this bird in 

 Wyoming. Drexel took a specimen at Fort Bridger in 1858; 

 Merriam found them in Yellowstone park in 1872; Williston 

 took a single specimen at Lake Como in early June, 1879 ; Bond 

 has taken them at Cheyenne and there is a specimen taken and 

 mounted by him in the Cheyenne High School. More data 

 concerning this species is very desirable and all of those inter- 

 ested in the birds of the state should keep a sharp lookout. 



462. Contopus richardsonii (Swains.). 

 Western Wood Pewee. 



Summer resident ; common. Breeds usually in the pine 

 and spruce timber up to 9,000 feet. Drexel took this species 

 at Fort Bridger, 1858. Grinnell has furnished notes on this 

 species as follows : "Taken Yellowstone park, 1875. I fre- 

 quently notice this species in the Lower Geyser basin (Yel- 

 lowstone park), but did not observe it at any other point on 

 the route. Very abundant on the Medicine Bow river, wherev- 

 er large timber was to be found." Merriam reports it from 

 Yellowstone park ; Coues refers to two specimens taken on 

 Bitter Cottonwood creek ; Jesurun notes that they are common 

 about Douglas ; Bond has taken numerous specimens at Chey- 

 enne. Cary makes the following note on the occurrence of 

 this species near Newcastle : "Partial to 'wait-a-bit' brush in 

 the rocky heads of the canons. Here the shy little flycatcher 

 is frequently seen catching insects around the rim rock on a 

 hot day, uttering at intervals its sharp 'ke-wick, ke-wick.' ' : 



I have observed this bird in the Bear Lodge mountains, 

 near Sundance, in the Big Horn mountains near Buffalo, on 

 Meeteese creek in the Absaraka range, in the Medicine Bow 

 and Laramie mountains. There are three skins in the Uni- 

 versitv collection that were taken in Albanv countv.
