Birds of Pennsylvania. 247 



268. Dendroica palmarum hy2iochrysca Ridgw. 



Yellow Palm Warbler.* 672a. " Said to differ in being more briglitly and 

 continuously yellow on the under parts, with the streaks confined 

 mostly to the sides, broadly tcar-rshaped, instead of linear, reddish, 

 instead of dusky ; lower eyelid yellow, not whitish ; back bright olive. 

 Habitat— 'Atlantic States, from East Florida to Nova Scotia.' Accord- 

 ing to this, hypochrysea should be the common bird of the Atlantic 

 States and what is above described as trwepalmarum should bo the bird 

 of the interior. But I have little faith in the validity of the physical 

 characters assigned, and none in the geographical distinctions sought to 

 be established." — Coues. 



The "Palm Warbler," a common spring and fall migrant in Eastern and 

 Central Pennsylvania, may be seen on the ground, in fields, along the 

 fences and by the roadsides. It is seldom observed to light in trees and 

 bushes to feed as is the common habit of others of its genus.

 resident. 



272. S. montacilla (Vieill.).

 have been taken in summer in Chester county, where it probably some- 

 times breeds. 



273. *Geothlypis formosa (Wils.). 



Kentucky Warbler. 677. 



274. O. agilis (Wils.).

 autumn, however, it is rather common.

 the mountainous portions of Pennsylvania.

Yellow-breasted Chat. 683.

 and young of this species were a few years ago found in Chester county.

Wilson's Warbler. 685. Migrant spring and fall. 



279. *S. canadensis (Linn.).

Family Motacillid^e. The Wagtails. 



281. Anthus jjensilvanicus (Lath.). 



American Pipit. 697. Common spring and fall migrant about ploughed 

 grounds. 



*In consequence of the fact that T have in my possession no specimens of Pennsylvania birds, I 

 am unable to say whether palmarum or hypochrysea is the bird which is found here, hence 

 I have included both in this list.
