PERCHING BIRDS 



stalks, bark strips, grasses and moss, lined 

 with fine black rootlets. They are found ar 

 elevations of from two to ten feet above the 

 ground. Like the Wood Thrush the birds are 

 tame while sitting on the nest and will allow a 

 very close approach, without taking alarm; 

 nests are frequently found which are made al- 

 most entirely out of green 

 moss and are very handsome 

 structures. Their three to 

 five eggs are laid in May or 

 June; they are greenish blue, 

 spotted with brown of vary- 

 ing shades. Size .92 x .65. 

 Data. Eureka, California, Greenish blue 

 July 6, 1899. Nest in a fir tree, 5 feet from the 

 ground; made of moss and strips of redwood 

 bark. 4 eggs. 



758a. OLIVE-BACKED THRUSH. Hylocichla 



srvainsoni. 



Gray -cheeked Thrush 



Range.-Eastern North America, breeding Olive-backed Thrush 



chiefly north of the United States, but. locally in the northern parts, and abund- 

 antly in mountain ranges. 



The nesting habits and eggs of this eastern representative of the last species 

 are like those of that bird in all respects and the eggs cannot be distinguished 

 from those of ustulatus. 



758b. OLIVE-BACKED THRUSH. Hylocichla cedica 



Range. California and southern Oregon. 



Nesting habits and eggs identical with those of ustulatus. 



759. ALASKA HERMIT THRUSH. Hylocichla guttata guttata. 



Range. Pacific coast from British Columbia to Alaska. Winters in Mexico. 

 The Hermit Thrushes can readily be identified from any other by the reddish 

 brown tail which is in marked contract to the color of the back. The nesting 

 habits and eggs of this species are precisely like those of the eastern Hermit 

 Thrush, which is a sub-species of this. 



75Qa. AUDUBON'S HERMIT THRUSH. Hylocichla guttata auduboni. 



Range. Rocky Mountain region of the United States. Winters in Central 

 America. 



The nesting habits of this bird are like those of the next except that it more 

 frequently nests in bushes above the ground. The eggs are not distinctive.
