Vireo WESTERN BIRDS 



hear the sweet Vireo song, although the harsh call note 

 was sometimes given. These birds are easy to identify 

 because of the white line running from eye-ring to bill. 

 One year when we were in the Sierra Nevada Mountains 

 in Tulare County these Vireos were very abundant and 

 one near our cabin sang all day long, "Gee! Mary's 

 here!" in a musical voice. There were many nests and 

 on one of them a male was brooding and singing as he 

 did so. 



GENUS VIREO : BUTTON'S VIREO. 



Hutton's Vireo: Vireo huttoni huttoni. 

 FAMILY— VIREOS. 



Hutton's Vireo is a little fellow about four and one- 

 half inches long and is a California bird, which is found 

 west of the Sierra Nevada from Siskiyou County south 

 to San Diego. 



It is a dull colored midget that might, so far as 

 plumage and foraging habits go, be mistaken for the 

 Ruby-crowned Kinglet. The call notes are entirely 

 different and in its southern range it is helpful to know 

 that while the Kinglet is a winter visitor, for the most 

 part the Vireo is a summer resident, although they also 

 frequent the canyons in winter time. The end of tail is 

 straight, while that of Kinglet is emarginate. 



It is scarcely five inches long and has olive brown 

 uppers, dull white eye-ring, lores, and wing bars; dull 

 white olive parts tinged with yellow. 



Though preferring the oak regions of the mesas and 

 foothills, they are also found from the willow regions 

 of the lowlands to several thousand feet elevation in the 

 mountains.
