10 Black=billed Cuckoo Coccyius erythropfitlialmus. I 

 have found this species somewhat erratic. Some- 

 times equaling the above, but within the past few 

 years I am sure of only one pair. 2 



M. Downy Woodpecker IDrj'obates pubescens medianus. 

 Fairly constant. The flying squirrel frequently uses 

 the deserted nesting cavity of this little bird. Five 

 pairs seem to be the average number nesting. 10 



12. Red-headed Woodpecker MelanerpeservtJirocephaliis. 

 This is more of a lover of old orchard and heavy grove 

 timber than of our chestnut belt. It is, however, more 

 frequent than ten years ago. One pair may be found 

 in this tract. 2 



13 Flicker Colaptes auratus. From three t(j six pairs 

 breed annually. Most abundant in the more open 

 country to the south of us. 8 



14. Nighthawk Chordeiles virginiamis. Considering 

 it locally, it is perhaps nearly as rare as the Whip- 

 poorwill. 1 record one pair. 2 



15. Chimney Swift Chcetura pelagica. 1 know of no in- 

 stance where more than a single pair occupy the same 

 flue for nesting purposes. For the past three years 

 the local contingent numbering as high as fifty or sixty 

 individuals have roosted in one of our chimneys prev- 

 ious to migrating. We have at least sixteen pairs of 

 breeding birds. 32 



16. Ruby-throated Hummingbird Trochilus coliibris. 

 1 am not sure that as many as four or five pairs do not 

 breed within the given area, but 1 have positive proof 



of only two pairs in any one year. 4 



17. Kingbird Tyrannus tyrannus. Present every sea- 

 son but extremely variable. Five pairs found in one 

 vear but the normal number is less than half. 4 



18. Crested Flycatcher Myiarchus crinitus. Totj noisy 

 to be overlooked, yet secretive enough in domestic 

 affairs. Averages eight pairs. 16
