 629. Lanivireo solitarlus solitarius (Wils.). Blue-headed 

 Vireo. 



The Blue-headed or Solitary Vireo nests regularly 

 and commonly thruout the mountain forests of the state 

 within the Canadian fauna. In suitable places within the 

 northern tier of counties, it is one of the characteristic 

 birds. Tho I have found thi3 KXlffl species nesting on the 

 Pocono Plateau as far south as the Delaware Water Gap, it 

 is apparently much more abundant in Sullivan, Wyoming, 

 Lycoming, Elk, Potter, McKean, Clinton, Cameron, and Warren 

 Counties and along the Alleghanies to Blair and Cambria 

 Counties, tho I have not noted it in Center County. 



631. Vireo griseus griseus (Bodd . ) . White-eyed Vireo. 



The White-eyed Vireo is very locally distributed 

 during the breeding season in the southern half of the state, 

 breeding most frequently in the Carolinian fauna, rarely in 

 the Alleghanian, and only occuring as a strag^Ler in the 

 Canadian . It is apparently most common along the southern 

 tier of counties east of the main ridge of the Alleghanies, 

 in portions of Delaware, Chester, Lancaster, York, Adams, 

 and Franklin Counties. Mr. J. W. Jacobs took one nest at 

 Waynesburg in 1893, but the bird is very scarce there. It 

 breeds north thru portions of Montgomery, Bucks, Berks, 

 Lebanon, and Dauphin Counties but always seems to be very 

 local and uncommon.
