39. Habia ludoviciana. Rose-breasted Grosbeak. — Rather com- 

 mon ; several pairs seen in tree-cleared places where there were plenty of 

 tangles' and a small maple now and then to perch upon. 



40. Passerina cyanea. Indigo Bunting. — Very few were noted, not 

 more than three during the whole two weeks. 



41. Piranga erythromelas. Scarlet Tanager. — Several single birds 

 and one pair in tall maple and beech grove. Not seen among the 

 hemlocks. 



42. Chelidon erythrogastra. Barn Swallow. — -The only Swallow- 

 seen ; common around houses, six nests under outside eaves of the 

 Captain's house, scattered, however, and not in colonies as the Eave 

 Swallows build. A singular fact came to note, viz. : A female was found 

 dead on her nest resting in a most natural position and was probably 

 frozen during the frost on the 1st of June. The skin was dry and hard. 



(One Petrochelidon licnifrons, Cliff Swallow, was taken by John Reese 

 August 3 ; specimen identified ; possibly a migrant. Breeds in Columbia 

 County. — R. Kester.) 



43. Ampelis cedrorum. Cedar Bird. — Abundant; several nests all 

 built unusually low ; one, one and one-half inches in diameter, built of 

 beard moss {Usnea), was five feet high in a birch. 



44. Vireo olivaceus. Red-eyed Vireo. — Abundant; singing in the 

 woods everywhere except in the primaeval hemlock, where the woods are 

 very quiet. 



45. Vireo solitarius. Solitary Vireo. — One pair with young just out 

 of nest, on the edge of the deep hemlock at the mouth of Straight Creek. 

 Found abundant by Dr. Dwight on North Mountain (Auk, IX, 1892, p. 

 138), and I should have expected it to be more common here.' 



46. Mniotilta varia. Black and White Warbler. — Uncommon; 

 only two or three were seen in second growth of hemlock, maple, etc. 

 From several records it appears that the bird is common or abundant in 

 the second hemlock growth of the Alleghanies (Stone, Dwight, and 

 Todd). 



47. Compsothlypis americana. Parula Warbler. — One female with 

 one young bird, seen among small trees on a stream. 



48. Dendroica aestiva. Summer Warbler. — Several seen ; one pair 

 building in the orchard. This bird does not seem to venture much into 

 the woods. 



49. Dendroica caerulescens. Black-throated Blue Warbler. — 

 Common in the woods where hemlock had been cut, as well as on 

 the edges of the deep hemlock woods. It was very evident that the 

 females were keeping close to their nests, as a great many males were 

 seen, always singing, as if to assure their better halt's that they were near 

 at hand. The same could be said of the next four varieties, only one 

 female being seen to ten males. 



50. Dendroica maculosa. Magnolia Warbler. — Common ; more so 

 if anvthing than the preceeding. One nest was found in a tiny wild
