penetrable swamps and slashings of Stone Valley and Bear Meadows. 

 One nest with two fresh eggs was found May 2, 1912. 



23. Melanerpes erythrocephalus. Red-headed Woodpecker. — 

 An abundant summer resident throughout the open valleys, nesting in 

 practically every woodlot and orchard about State College and the ad- 

 joining towns and sometimes raising two broods in a season. From a 

 number of nests examined, the earliest with six fresh eggs was found May 

 •26, 1910, and the latest with four fresh eggs on July 10, 1911. 



24. Colaptes auratus luteus. Northeun Flicker. — An abundant 

 'summer resident throughout the open valleys nesting most frequently in 

 orchards and woodlots. Less common in the more open mountain forests. 

 Earliest nest examined held eleven eggs on May 9, 1910; latest nest June 7, 

 1910, with seven fresh eggs. The average date when sets are completed 

 is May 12. 



25. Antrostomus vociferus vociferus. Whip-poor-will. — Quite 

 common summer resident throughout the mountain forests. It apparently 

 does not breed in the more open country. 



26. Chordeiles virginianus virginianus. Nighthawk. — Rare sum- 

 mer resident in the open country. Found about old fields where there is an 

 outcrop of flat stones. 



27. Chsetura pelagica. Chimney Swift. — The Swift is an abun- 

 dant summer resident throughout the open country about houses and, in 

 fact, wherever suitable chimneys are found where it may nest. Large 

 numbers breed in the capped chimneys of the chemistry building on the 

 College campus. 



28. Archilochus colubris. Ruby-throated Hummingbird. — Regu- 

 lar but rather scarce summer resident in the open valleys as well as along 

 the borders of the mountain forests. In the open country it breeds about 

 estates, in woodlands and in orchards. I have found but one nest, which 

 contained two fresh eggs on June 7, 1909. This was built in the College 

 orchard. 



29. Tyrannus tyrannus. Kingbird. — Abundant summer resident 

 of the open or cleared valleys, where it nests in nearly every fruit orchard. 

 The average time for complete sets of eggs is about June 6. 



30. Myiarchus crinitus. Crested Flycatcher. — Very common 

 summer resident throughout the valleys and open woodland, nesting most 

 abundantly in old apple orchards. The usual time for complete sets of 

 eggs is about Juno 5. 



31. Sayornis phoebe. Phcebe. — Very abundant summer resident, 

 nesting indiscriminately about out-houses, barns, ruined buildings, under 

 bridges or on the sides of rock ledges in the mountains. Near Pine Grove 

 in an old ore furnace, a nest of Phoebe was found with six distinct stories. 

 Average time for first sets April 28. 



32. Myiochanes virens. Wood Pewee. — Abundant summer resi- 

 dent, nesting usually in open woods, orchards or about estates. But three 

 Jiests have come to my notice.
