NORTH AMERICAN BIRDS EGGS. 331 



759a. Audubon Hermit Thrush. H. g. 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. 



759b. Hermit Thrush, H. g. pallasii. 



Range. Eastern North America, breeding in northern 

 United States and north to Labrador; winters in southern 

 United States. 



This species, which is noted for its sweet and musical song, 

 frequents damp swamps and thickets where it builds its 

 nest either on the ground or near it, like that of the Wilson 

 Thrush; it is made of shreds of bark, grasses, leaves and root- rR1 T 

 lets, lined with tine rootlets; the three or four eggs, which are ' 

 deposited in May or June, are bluish green and cannot, with certainty, be dis- 

 tinguished from those of the Veery; size .85 x .65. 



759c. Dwarf Hermit Thrush. H. g. nana. 



Range. Pacific coast of United States, from Washington, southward. 



The nesting habits and eggs of this slightly smaller and duller colored variety 

 are like those of the other Hermit Thrushes. 



[760]. Red-winged Thrush. Turdus iliacus. 



Range. An Old World species, accidentally straying to Greenland. 



This common European bird nests at low elevations in bushes or trees, laying 

 four or five bluish green eggs, spotted with reddish brown; size 1.05 x .75. 



761. American Robin, Merula migrator ia. 



Range. -North America east of the Rockies, breeding from the middle por- 

 tions of the United States, north to the Arctic Ocean. 



These common birds nest in trees about houses, in 



orchards, open woods, in corners of fences, on blinds on 

 id 



m^' jlk houses, and in fact almost every conceivable position. 



I B Their nests are made of grasses, firmly cemented together 



f with mud and lined with finer grasses; when placed in 



lP^ trees they are generally firmly saddled in crotches and 



^^^^ may be found at any height, from on the ground to 



sixty feet above it. Their eggs are greenish blue; size 



[Greenish blue.] 1.15 x .80. Eggs may be found at any time from May 



until July or August as they raise several broods a season. 



76 I a. Western Robin. M. m. proplnqua. 



Range. United States west of the Rockies and north to British Columbia. 



The habits of this species, which differs from the last only in the absence of 

 white tips to the tail feathers, are just the same as those of the eastern bird 

 and the eggs are not distinguishable. 



76 I b. Southern Robin. M. m. achrustera. 



Range. The Carolinas and Georgia. 



The eggs of this bird, which is said to be smaller and duller colored than the 

 northern variety, show no differences in any respect. 



762. St. Lucas Robin. Merula confinis. 



Range. Southern Lower California. 



This is a very much paler form of the American Robin; its eggs probably will 

 not differ from those of the others.
