274 Chaney, Birds of Mason County, Mich. [f^^y 



32. Haliseetus leucocephalus. Bald Eagle. — Only one pair was seen 

 about the lakes. Dr. Alfred Lewy of Chicago found an eagle's nest several 

 years ago in the woods on the sand hills. It was placed about sixty feet 

 from the ground in an oak, and on July 1 contained two large young. 



33. Falco sparverius. Sparrow Hawk. — Fairly common on the 

 wooded ridges. 



34. Otus asio. Screech Owl. — On the chilly evenings and early 

 dawns of September, the quavering call of this owl was heard frequently. 



35. Coccyzus americanus. Yellow-billed Cuckoo. Fairly common. 



36. Ceryle alcyon. Kingfisher. — Every suitable bank around the 

 lakes was in possession of a pair of these noisy birds. Young birds were 

 out in the last week in June. 



37. Dryobates villosus. Hairy Woodpecker. — Common in the dense 

 woods. In September they became quite abundant, and seemed to prefer 

 the open or burnt-over woods. 



38. Dryobates pubescens medianus. Downy Woodpecker. — Com- 

 mon, especially during September. 



39. Sphyrapicus varius. Yellow-bellied Sapsucker. — A pair seen 

 on July 12 on a burned over hillside was probably breeding, although I 

 failed to locate the nest. Migrating birds were seen during the latter half 

 of September. 



40. Melanerpes erythrocephalus. Red-headed Woodpecker. — A few 

 pairs were ol)served al)out the farms and clearings. 



41 . Colaptes auratus luteus. Flicker. — Very common, nesting around 

 clearings and in stumps in open fields. Nests contained young early in 

 July. The farmers complained that the " Yellowhammers " did a great 

 deal of damage to their corn crops. 



42. Antrostomus vociferus. Whip-poor-will. — At dusk and early 

 dawn these noisy fellows kept up a great racket around the edge of Upper 

 Hamlin. Birds were occasionally flushed during the daytime in the hard- 

 wood forests. 



43. Chordeiles virginianus. Nighthawk. — Abundant over the lake 

 and woods in the late afternoon and evening. On July 2, while crossing a 

 burned-over ridge, I flushed a Nighthawk from a set of incubated eggs 

 which were placed on the bare ground near a partly burned log. Migiation 

 in large flocks occurred between August 23 and Sept. 9. 



44. Chsetura pelagica. Chimney Swift. — Very abundant in the towns 

 but only a few pairs were observed about Upper HamHn. A nest con- 

 taining five eggs far advanced in incubation was discovered on July 11, on a 

 wall in a stable of an unoccupied lumber camp in the midst of the woods. 



45. Archilochus colubris. Ruby-throated Hummingbird. — Fairly 

 common in tlie few suitable localities. 



46. Tyrannus tyrannus. Kingbird. — This species might be considered 

 almost aquatic in its nesting habits, as the nests were invariably placed in 

 stumps projecting out of the water, often at a considerable distance from 

 the shore. Nests with eggs — always three in number — were seen up to 

 the middle of July.
