Bird- Lore 



What Bird is This? 



Field Description. — Length, 5.50 in. Above, olive-green, iiead slaty ; throat and breast blackish margined with 

 whitish ; belly yellow ; no white eye-ring : no white in tail. 



Note. — Each number of Bird-Lore will contain a photograph, from specimens in 

 the American Museum of Natural History, of some comparatively little-known bird, or 

 bird in obscure plumage, the name of which will be withheld until the succeeding number 

 of the magazine; it being believed that this method of arousing the student's curiosity will 

 result in impressing the bird's characters upon his mind. The species figured in August 

 is a Savanna Sparrow in fall plumage.
