COMPSOTHLYPIS, Cab. 



(Chloris, Boie. Parula, Bonap.) 



O. americana, L. Blue Yellow-backed Warbler. Parula Warbler. 



Clear ashy blue ; large golden-green patch on back ; yellow 

 below ; belly white ; brown band across breast ; white wing 

 bars; female paler. Length, 4| inches; tail, 2 inches. 



"Abundant from the beginning of May. Seldom remains 

 during the summer. Returns in August. Prefers pines and 

 cedars to other trees, and is not as restless as warblers generally 

 are, but remains on one tree for a long time. Have found no 

 nests of this species." [C. C. A.] 



DENDROICA, Qr. 



D. tigrina, Gmel. (Perissoglossa, Baird.) Fringed-tongue Warbler. 

 Cape May Warbler. 



Olivaceous above, with darker streaks ; rump and sides of neck 

 bright yellow ; yellow below, streaked with black ; crown nearly 

 or quite black ; a white wing patch ; orange-brown ear coverts ; 

 female duller, with no reddish or black about head. Length, Si- 

 inches; tail 2 inches. 



"Arrives in May, but is not an abundant species. Author has 

 met with but two specimens. The common name would seem to 

 suggest New Jersey as its principal ' habitat.' " [C. C. A.] 



D. aestiva, Gmel. Summer Warbler. Golden Warbler. Yellow 

 Warbler. 



Plumage chiefly yellow; wings and tail dusky, edged with 

 yellow ; back olive yellow ; breast and sides with orange-brown 

 streaks ; female scarcely streaked. Length, 5 J inches ; tail, 2^ 

 inches. 



" Very abundant. Arrives in May, and remains during the 

 summer. Builds in birch trees, especially those skirting streams, 

 though by no means there exclusively. Is a sociable bird, and 

 seldom seen in the woods or unfrequented swamps. Lives like 

 all the tribe, exclusively on insects, and is a very useful bird to 

 fruit-growers. Have generally all disappeared by September 

 20th."
