350 WOOD WARBLERS. 



646. Helminthophila. celata (Sat/). ORANGE-CROWNED WARBLER. 

 Ad. Upper parts rather ashy olive-green; feathers of the crown orange- 

 rufous at the base ; wings and tail edged with olive-green and without white ; 

 eye-ring yellow ; under parts greenish yellow, obscurely streaked with dusky 

 on the breast. Ivn, Similar, but without orange-rufous in the crown ; upper

 T., 1-95 ; B. from N., -31. 



Range. Breeds in the interior of British Columbia, and as far north as 

 the " Yukon and Mackenzie River districts, and southward through the 

 Rocky Mountains; winters in the South Atlantic and Gulf States and 

 Mexico." 



Washington, casual T. V., one instance, Oct. Sing Sing, A. V. Cam- 

 bridge, rare T. V.,in fall, Sept. 30; Oct. 2. 



Nest, of leaves and fine grasses, on or near the ground. Eggs, four to five, 

 white, with specks or spots of cinnamon-brown or rufous, more numerous at 

 the larger end, -63 x -49. 



Orange-crowned Warblers are rare in the North Atlantic States. 

 In Florida, where they are common in the winter, they evidently pre- 

 fer the densely foliaged live and water oaks. Their sharp chip is suffi- 

 ciently characteristic to be recognized after one has become thoroughly 

 familiar with it. Their song, which I have never heard, is described 

 by Colonel Goss as consisting of " a few sweet trills uttered in a spir- 

 ited manner, and abruptly ending on a rising scale." 



647. Helminthophila peregrina ( Wih.). TENNESSEE WARBLER.

 fined from the bright olive-green back and rump ; wings and tail edged with 

 olive-green ; no white wing-bars ; inner margin of inner vane of outer tail- 

 feathers generally white at the tip ; under parts white, sometimes tinged with 

 yellow. Ad. 9 . Similar, but crown tinged with greenish and under parts 

 washed with yellowish. Im. Upper parts uniform olive-green ; under parts 

 washed with yellowish ; under tail-coverts white. L., 5-00 ; W., 2-63 ; T., 1-69 ; 

 B. from N., -32. 



Remarks. The adults of this and the two preceding species may be dis- 

 tinguished with ease; immature birds, however, are frequently confused. 

 The Nashville is distinctly yellow on the breast and under tail-coverts ; the 

 Orange-crowned is pale greenish yellow, with dusky streaks and yellow 

 under tail-coverts ; the Tennessee is pale greenish yellow, without streaks, 

 and with the under tail-coverts white.

 York, and New Brunswick northward; winters in Central America.
