BIRDS OF PENNSYLVANIA. 247 



26a Dendroica palmarum hypochrysea Ridgw. 



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

 continuously yellow on the under parts, with the streaks confined 

 mostly to the sides, broadly tear-shaped, 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 true palmarum should be 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.

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

 am unable to say whether p'lhnarum or hypochrysea is the bird which is found here, hence 

 I have included both in this list.
