^'°^912"^^] Harlow, Breeding Birds of Center County, Fa. 471 



15. Otus asio asio. Screech Owl. — Common permanent resident 

 throughout the open country. In spite of the fact that the author has 

 found but one nest, he has often seen the young birds still in the down and 

 at least two pairs breed on the College campus. Screech Owls here show 

 a marked preference for holes in old orchard trees and in large elms along 

 the creeks. The gray form is more prevalent here. A nest with three 

 eggs found April 13, 1912. 



16. Bubo virginianus virginianus. Great Horned Ow l. — A rare 

 but regular permanent resident apparently restricted to the wilder moun- 

 tainous regions. It has been noticed in the \dcinity of Bald Knob, Bear 

 Meadows and Stone Valley. In spite of diligent search, no nests have been 

 found, but the birds have been seen Feb. 25, 1910, during their breeding 

 season near Monroe Furnace. 



17. Coccyzus americanus americanus. Yellow-billed Cuckoo. 

 — Regular, but rather uncommon summer resident, most frequently 

 found in second growth, or damp thickets in the more open country where 

 it breeds. 



18. Coccyzus erythrophthalmus. Black-billed Cuckoo. — 

 Scarce summer resident, the more frequent form in the thickets and second 

 growth of the mountainous regions in the vicinity of Bald Knob, Bear 

 Meadows and Stone Valley. 



19. Ceryle alcyon alcyon. Belted Kingfisher. — Regular and 

 fairly common summer resident in suitable localities throughout the more 

 open country. Rarer along the mountain streams. The Kingfisher 

 builds either in the banks of streams or less commonly in quarries or sand 

 banks remote from water. The following nests have been found. 



May 22, 1909. One fresh egg. 

 May 11, 1910. Six fresh eggs. 

 May 18, 1912. Seven incubated eggs. 



20. Dryobates villosus villosus. Hairy Woodpecker. — Scarce 

 permanent resident in the larger bodies of timber; most frequently found 

 along the base of the mountains. It has been noted throughout the breed- 

 ing season near Pine Grove Mills, in Stone Valley and along the base of 

 Mount Nittany, near McBride's Gap and at Waddles. 



21. Dryobates pubescens medianus. Downy Woodpecker. — A 

 very common permanent resident in the open country, but its nests are 

 difficult to find. During the breeding season it is most frequently observed 

 in woodlots, groups of trees near streams, or in orchards. In the mountains 

 it is uncommon. We have noted but two nests. The first was found 

 May 30, 1909, and contained four half fledged young, while the second 

 held a completed set of 5 eggs on May 19, 1912. 



22. Phloeotomus pileatus abieticola. Northern Pileated Wood- 

 pecker.— A scarce permanent resident now restricted to the mountainous 

 districts and the wilder portions of the barrens. The extreme shyness of 

 these birds renders observation most difficult. The Pileated Woodpecker 

 occurs regularly throughout the breeding season in the wild, almost im-
