 low; upperparts yellower. Winter specimens are 

 whiter below but are still conspicuously yellow.

 ward, east of Hudson Bay; migrates through Atlantic States and 

 •winters in Florida and west to Louisiana, 



673. Prairie Warbler {Dendroica discolor). L. 4.7. 

 Wing-bars yellowish; tail-patches white. Ad. tf.

Lawrence Warbler {Helminthophila lawrencei). Re- 

 sembles No. 641, but has a black breast patch and 

 a broad black stripe through the eye as in No. 642. 

 It is believed to be a hybrid between the two. Some 

 15 specimens are known. Its notes are said to re- 

 semble to those of both No. 642 and No. 641. 



Brewster Warbler {Helminthophila leucobronchialis) . 

 Resembles No. 642 above, but is white usually 

 tinged with yellow below, this type being connected 

 with No. 641, by specimens showing more green above 

 and yellow below. Hybridism and dichromatism are 

 believed to account for these birds of which somewhat 

 over a hundred specimens are known, chiefly from the 

 lower Hudson and Connecticut Valleys. Some songs 

 resemble those of No. 642, others those of 641.
