FLYCATCHERS 



Olive-sided flycatcher, Nuttallornis 

 borcali.s. 7.50 



Distribution: North America from Hud- 

 son Bay to Alaska, southward in coniferous 

 timber over the higher parts of the United 

 States to the Carolinas, and in the coniferous 

 forests of the western United States from 

 British Columbia south to Mexico. INIigrat- 

 ing in winter to South America. 



With the exception of the kingbirds the 

 olive-sided flycatcher is the largest of the 

 family to be found on the Pacific Coast. It 

 inhabits tall timber along the crests of the 

 hills, and well up into the mountains, where 

 it may be seen perched on the higher parts of 

 some dead tree watching for flying insects. 

 Its whitish underparts, raised crest and half- 

 droope.d wings will be noticed if examined 

 through a field glass as it stands on its lofty 

 vantage point. Its excursions will sometimes 

 take it far afield but it wull soon return to the 

 same tree, w^hich is usually near its nest. 



The call note of the olive-sided flycatcher 

 is a shrill pit-pip, pu, pu-pip while its song is 

 a loud, i\vii^\\mg s-e-c-h-c-r-c , or tliree ch-e-e-r-s 

 which may })e heard a long way off. Its nest 

 is placed high in fir or sj^ruce and is one of 

 the most difficult to find. It is beautifully 

 made of small twigs, rootlets and green moss,
