278 BIRDS OF PENNSYLVANIA. 



Helminthophila celata (SAY.). 



Orange-crowned Warbler. 



DESCRIPTION. 



"Above grayish olive-green, rather brighter on the rump. Beneath entirely 

 greenish yellowish-white, except a little whitish about the anus; the sides tinged 

 with grayish-olivaceous. A concealed patch of pale orange-rufous on the crown, 

 hidden by grayish tips to the feathers. Eyelids and an obscure superciliary line 

 yellowish-white, a dusky streak through the eye. Inner webs of tail feathers broadly 

 edged with white. 



"Female with little or none of the orange on crown, and the white edgings to inner 

 webs of tail feathers. 



"Young lacking the orange entirely, and with two fulvous-whitish bands on the 

 wings. Length 4.70 ; wing 2.25 ; tail 2.00."* Hist. N. Am. B. 



Habitat. Eastern North America (rare, however, in the northeastern United 

 States), breeding as far northward as the Yukon and Mackenzie river districts, and 

 southward through the Rocky mountains, and wintering in the south Atlantic and 

 Gulf States and Mexico. 



The Orange-crowned Warbler occurs in Pennsylvania as a very rare 

 and irregular straggler, during the spring and fall migrations. A fine 

 male was shot by the late C. D. Wood, November 2, 1867, in Bucks 

 county. Dr. Spencer Trotter records f the capture of a specimen in 

 Philadelphia county. I have never met with this species. 



Helminthophila peregrina (WiLS.). 



Tennessee Warbler. 



DESCRIPTION. 



Length 4.71 (average of four adult males); extent 7^ (two males); wing 2.65 

 (average four males); tail 2 or a little less. The female is a trifle smaller. Bill 

 (dried specimens) -maxilla blackish; mandible paler; legs blackish, feet brownish- 

 yellow. Upper parts olive-green, brightest on rump ; top and sides of head and 

 neck, more or less ash-gray in some specimens ; below chiefly white ; lores dusky ; 

 a whitish ring around eye, and a line of same above it ; outer tail feather has an 

 obscure white spot on edge of inner web near end. Specimens taken in the fall have 

 most of ash-gray of head and neck replaced with olive-green, and the lower parts, 

 except under tail-coverts and patches on abdominal region which are white, are 

 greenish-yellow. 



Habitat. Eastern North America, breeding from northern New York and 

 northern New England northward to Hudson's Bay territory ; Central America in 

 winter. 



The Tennessee Warbler, according to my observation, is found in 

 eastern Pennsylvania as a very rare straggler during the spring migra- 

 tion, but in the autumn (September) it is often common, frequenting 

 apple orchards, woods and thickets. Although sometimes found quite 

 plentifully as an autumnal sojourner in the eastern portions of the state, 

 I do not regard it as a regular fall migrant east of our principal rnount-
