AMERICA.:^ WARBLERS. 105 



Nestlings. Similar to the young female, but browner above, with in- 

 distinct wing bands of buff, and with buff on throat, chest, and sides. 



Dimensions. Length, 5. ; o ; stretch, 7.oo ; wing, 2.00 ; tail, i.7o; bill, 

 42 ; tarsus, .64. 



Comparisons. Readily distinguished from all other of our warblers, 

 excepting the next, by the short wings, their tips folding at the base of 

 the tail, plain colors above and yellow throat ; the adult males may be fur- 

 ther distinguished by the black mask. 



Gexekal Habits. For general and l)reeding habits, ac- 

 count of nests and eggs see these subjects under Northern Yel- 

 low throat, all of which will answer for those of this species. 



^[iGATiox AND BiiEEDiXG Raxgk. I havc uow added 

 this species to the fauna of ^ew England on the strength of 

 an adult male in my collection taken at Genterdale, Rhode Is-

 lection were specimens of the common northei-n Yellow-throat. 

 Occurs regularly during the breeding season from southern 

 Pennsylvania, Yirginia, and Maryland, southward. 1 have a 

 young male taken at New River, North Carohna, December 

 15, 1900, by the Maynard-Pratt Exjoedition; also winters in the 

 Bahamas.

Size, larger, from 5.25 to 5.75. Colors darker than in 

 the last, with the^ellow beneath much more extended. 



Comparisons. Decidedly darker above than in the Maryland Yel- 

 low-throat ; the yellow beneath is deeper in shade, and extends over near-

 •the southern species.
