158 WARBLER. 



light slate-colour, streaked with black, extending under the wings ; 

 belly and vent white, the latter spotted with blue. 



The female differs but little, the colours being only less vivid; in 

 October the slate-colour changes to brownish olive, the black streaks 

 incline greatly to brown, and the white stained with brown ; the tail 

 coverts retain their slaty-hue, and the yellow on the crown, and sides 

 of the breast, nearly obliterated. 



The young of the first season are brown olive above, till February 

 or March, then change to fine slate; in the middle of April the 

 change is complete ; while in the brown olive dress, the yellow on 

 the breast and crown is scarcely discernible, except the feathers 

 are separated, yet that on the rump is vivid, the black spot on the 

 cheeks is also then observed ; from the above we learn, that the three 

 birds described as distinct, are merely different ages of one and the 

 same species. It often winters in Virginia, Carolina, and Georgia, 

 and is called Myrtle Bird, as it feeds on the berries of that plant.
