14 PROCEEDINGS OF THE 



at Tamarack Swamp on June 23, and again in the Kettle 

 Creek Valley on June 25. 



9. Buteo borealis. Red-tailed Hawk. — A single individual 

 was observed on June 23, in the depths of Tamarack Swamp. 



10. Megascops asio. Screech Owl. — Heard frequently during 

 the evening in and around Tamarack Swamp. 



Mr. Campbell, at whose farm house we stayed on the edge of 

 the Swamp, informed us that there were several different species 

 of owls resident there. He mentioned especially the Great- 

 horned Owl, with which he seemed to be perfectly familiar. 



11. Ceryle alcyon. Belted Kingfisher. Tolerably common 

 along Little Kettle Creek in Potter County. 



12. Dryobates villoms. Hairy Woodpecker. — Fully as abun- 

 dant as the Downy, but confined largely to the deep forest. 



13. Dryobates pubescensmedianu.s. Downy Woodpecker. — Com- 

 mon everywhere, both in the deep woods and in the open country. 



Ceophloeus pileatus abieticola and Sphyrapicus varius were not 

 observed either at Tamarack Swamp or in Potter County, and if 

 they do occur as breeders must be confined largely to the deepest 

 portions of the primeval forests in Stewardson township, into 

 which we did not penetrate. 



14. Colapjtes auratus luteus. Flicker. — Common everywhere. 



15. Antrostomus vociferus. Whip-poor-will. — This species 

 seemed to be not uncommon, several being heard around Tama- 

 rack Swamp every evening. Also observed at Oleoua on the 

 evening of June 25, where it seemed to be rather out of place 

 amidst the primeval forest. Doubtless, however, just as at 

 North Mountain (Stone), and other localities in the northern 

 part of Pennsylvania, this species has onlj' become common 

 since lumbering began. 



16. Chordeiles virginianus. Nighthawk. — Noted only twice, 

 on June 23 and 24, at Tamarack Swamp. 



17. Chaetura pdagica. Chinniey Swift. — Common through- 

 out the open country. 



18. Trochilus colubris. Ruby-throated Hummingbird. — Com- 

 mon. 



19. Tyrannus tyrannus. Kingbird. — Noted in the open coun- 

 try, especially between New Bergen and Germania, Potter 

 county.
