The June Bird Census 



171 



What Bird Is This? 



Field 'Description. — Length. 5.50 in. Crown dark brown, a grayish line through its center, a burfy streak over 

 the eye: back streaked with black, whitish and brownish: tail-feathers pointed: throat whitish ; breas; and sides 

 buffy; abdomen white. 



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

 the American Museum of Natural History, of some widely-distributed, but, in tiie 

 eastern United States, at least, comparatively little-known bird, 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 

 on his mind far more strongly than if its name were given with its picture. 



The species figured in August is the female Black-throated Blue Warbler, a fall 

 specimen with the white spot at the base of the primaries not visible beyond the coverts. 

 Few Warbler |)luiTiages are more dithcult to identify.

 observation recjuired to make them of value in this connection. A mere 

 enumeration of the species seen even when accompanied b\- the statements 

 of "Common," "Abundant," etc., does not aitl us in learnifiL: with com - 

 jiarative exactness the number of itidi\idual birds occup\iniz a L!;i\i'n area.
