Baily, Birds of Northern Elk County, Pa. [^ { k 



cherry, about 3 feet high, at the side of a log road in a deep wood of 

 birch, maple, and oaks, and some second growth hemlocks. The female 

 sat so close that I touched the tree before she flew. This little bird, as it 

 covered an almost invisible nest of hairlike grass, was one of the prettiest 

 pictures in my experience. 



51. Dendroica pensylvanica. Chestnut-sided Warbler. — Com- 

 mon ; more females of this species were seen than either of the preced- 

 ing two, but nearly always in overgrown, open places. 



52. Dendroica blackburniae. Blackburnian Warbler. — Common; 

 principally high up in the hemlocks near the streams; only one female 

 noted. The males were almost invariably singing. 



53. Dendroica virens. Black-throated Green Warbler. — Com- 

 mon ; generally in the same environment as the last species. 



54. Seiurus aurocapillus. Ovenbird. — Common in the dry upper 

 woods. 



55. Seiurus noveboracensis. Water-Thrush. — Common; especially 

 on the clear streams not poisoned by the chemical works or tanneries, 

 where only one was observed. One nest with eggs under the root of 

 a tree, and a number of just fledged birds were seen. This bird begins to 

 get common just west of the Alleghanies. 



56. Geothlypis trichas. Maryland Yellow-throat. — Common in 

 its usual haunts. 



57. Sylvania canadensis. Canadian Warbler. — Common ; singing 

 constantlv ; seen less among the hemlocks than elsewhere, except on 

 Straight Creek. 



5S. Setophaga ruticilla. Redstart. — Only one was seen, this on the 

 Clarion, and it was not observed in the mountains by either Messrs. 

 Dwight, Stone, or Todd, but Warren speaks of it as being most common 

 in the higher mountain regions, mentioning especially McKean, Potter, 

 Sullivan, Centre, Blair, Lycoming, Crawford and Erie Counties. I found 

 it common and several nests in very open places at Point Pelee, on the 

 warm, flat Canadian shore of Lake Erie where the Summer Warbler, 

 Baltimore Oriole, Brown Thrasher, and five Swallows, were abundant, 

 a much more mild environment. 



59. Galeoscoptes carolinensis. Catbird. — Very common, a number 

 of nests being found. There happens to be a number of places on the 

 southeastern slopes of some of the rolls, covered with raspberry bushes, 

 well adapted for some of the more southern varieties, but few of them 

 seem to take advantage of the fact. 



60. Troglodytes aedon. House Wren. — Common in cleared woods 

 as well as around houses. 



61. Troglodytes hiemalis. Winter Wren. — Abundant in the tall 

 open woods as well as in the cool hemlocks near the streams ; most 

 common on Straight Creek, which is by far the coolest in the locality. 



62. Certhia familiaris americana. Brown Creeper. — Not common; 

 only about three seen, which were very hard to locate, and it may be
