WARBLER. 199 



A. — Length five inches and a half, breadth nine. Bill dusky 

 red ; i rides dark brown ; plumage above fine yellowish olive, beneath 

 yellow ; thighs and vent very pale ; wings dusky, the feathers edged 

 yellowish white ; tail rather forked, dusky, edged as the quills ; two, 

 or more, of the outer feathers marked with a longish white spot on 

 the inner webs ; legs dull yellow. 



The female is much paler than the male. The young bird 

 differs from both, as the yellow is wholly wanting. From being- 

 smaller, and the colours less defined, it is probable that the first 

 described may be a young bird. 



Inhabits Georgia, and there called Yellowhammer, or Olive- 

 backed Warbler ; builds the beginning of May, and is peculiar, in 

 fastening the top of the nest to the twigs, in the fork of the extremity 

 of the limb of a tree, generally an Oak ; it is formed of dried bark 

 of the wild grape, rotten wood, and spider's webs, lined with pine 

 straw, though sometimes intermixed with some large pieces of the 

 bald-faced hornet's nest, on the outside. 



The egg is bluish white, the larger end nearly white, and marked 

 there with small, dark, purplish spots; often associates with the 

 Sparrows in winter, but in summer chiefly frequents Pines, in small 

 flocks. A singular circumstance in this bird is, that the adult male 

 becomes in spring, and the first of the summer, a dirty dingy colour, 

 though it is in season for song, and the breast dirty green ; but that 

 it gains the bright plumage the middle of August, and so continues 

 through the winter. M. Azara saw this in Paraguay once only in 

 September.
