586 HISTORY OF THE 



GENUS SYLVANIA NUTTALL. 



"Bill broad, depressed; the lateral outlines a little concave; the bristles 

 reaching not quite half way from nostrils to tip. Culmen and commissure 

 nearly straight to near the tip. Nostrils oval, with membrane above. Wings 

 pointed, rather longer than the nearly even but slightly rounded tail; first quill 

 shorter than the fourth, much longer than the fifth; the second and third quills 

 longest. Tarsi rather lengthened, scutellar divisions rather indistinct; the 

 middle toe, without claw, about three-fifths the tarsus. 



"This genus is distinguished from Setophaga mainly by stouter feet and 

 longer toes, shorter and more even tail, narrower bill, etc. The species are de- 

 cidedly rnuscicapine in general appearance, as shown by the compressed bill 

 with bristly rictus. The type (8. mitrata) is very similar in character of bill to 

 Dendroica castanea, but the wings are much shorter; the tail longer and more 

 graduated; the legs and hind toe longer, and the first primary shorter than the 

 fourth (.15 of an inch less than the longest), not almost equal to the longest. 

 The species are plain olive plumbeous above, and yellow beneath."

HABITAT. Eastern United States; north to Connecticut, .New 

 York, Iowa, etc. ; west to eastern Nebraska and Texas; south in 

 winter to the West Indies, eastern Mexico and southern Central 

 America. Probably breeds throughout its United States range. 



SP. CHAR. Wing without any markings. Upper parts olive green. Inner 

 webs of outer tail feathers with white patches. Adult male: Forehead and ear 

 coverts gamboge yellow; rest of head and neck, including chest, uniform deep 

 black; rest of lower parts pure gamboge yellow. Adult female: Similar to the 

 male, but with black of head usually much less distinct, sometimes wholly ab- 

 sent, that of upper portions being replaced by olive green, that of the throat, 

 etc., by gamboge yellow. Young, in first autumn: Similar to adult female, 

 without black on head. (Ridgway.)
