Warbler WESTERN BIRDS 



markings, makes identification easy. While this bird 

 appears on the Pacific coast, in most localities as a 

 migrant or winter visitor, it is not nearly so common 

 as is the Audubon, its western representative. 



The nest is of the usual fibers and grasses, and placed 

 from five to ten feet in a coniferous tree. Chapman 

 says that the birds are very fond of bayberries and that 

 their movements are governed largely by the presence 

 of these berries. Banded together in loose fiocks they 

 forage in old fields and scrubby growths. 



The common call is a sharp tchep which makes identi- 

 fication easy even when the bird is not in sight. Thayer 

 gives the song as a loud and silvery sleigh-bell trill — a 

 vivid, sprightly utterance — often more or less broken 

 up into separate notes, particularly in its diminuendo 

 termination.

 FAMILY— WOOD WARBLERS. 



While the Myrtle Warbler strays to the Pacific coast 

 during the winter months, it is not nearly so common as 

 is the Audubon, which closely resembles it, and which 

 breeds from the tree limit in northwestern Alaska south 

 to the mountains of southern California, northern Ari- 

 zona, and southeastern New Mexico; east to the Black 

 Hills, South Dakota, and western Nebraska, wintering 

 in the valleys of California; accidental in Pennsylvania 

 and Massachusetts. 



The Audubon Warbler differs from its eastern cousin 

 chiefly in having a bright yellow throat where the Myrtle 

 has a white one; the side of the head is gray, not black;
