Lincoln's Song Sparrow. 



Forbush's Song Sparrow. Similar to 



birds of the year are much browner above, with considerable brownish-yellow streaking besides 

 the black markings ; top of head quite like back, the ashy stripes not being established ; whole 

 under parts brownish-yellow, merely 

 paler on throat and belly, dusky-streaked 

 throughout. N. Am. at large; a pecu- 

 liar species, not so well known as it might 

 be, less numerous in the Atlantic States 

 than in the interi'ir and West ; and keep- 

 ing very close in shrubbery. Migratory ; 

 winters in the South ; breeds at least 

 from N. New York and New England to 

 Arctic regions, and in the West S. at 

 least to mountains of Colorado and Cali- 

 fornia; S. in winter to Panama. Nest- 

 ing like that of the Song Sparrow, and 

 <'ggs not distinguishable with certainty; 

 they average smaller, about 0.75 X 0.55; 

 the ground color varies from whitish to 

 greenish-white or brownish- white, and the 

 markings are usually coarsely blotched.
