pale yellowish or whitish, especially noticeable as 



triangular spots on wing-coverts. But these speedily disappear, when a plumage scarcely 

 diflerent from that of the adult is assumed. The most strongly marked species of the genus ; 

 in no other are the spots below so large, sharp, numerous, and generally dispersed. In the 

 Hermit, our only other Thrush showing both tawny and olive on ujjper parts, the position 

 of the two colors is reversed, tawny occupying the rump, olive the head. Eastern U. S., N. 

 to Massachusetts, Michigan and Southern Canada, W. to the Plains, S. in winter to Guate- 

 mala; Cuba; a famous vocalist, c(nnmon in low damp woods and thickets; migratory; breeds 

 throughout its U. S. range. Nest in bushes and low trees, of leaves, grasses, etc., and mud ; 

 esrgs usually 3-4, plain greenish-blue like the Robin's, but smaller: 1.08 X 0.70.
