69. Dendroica pensylvanica. Chestnut-sided Warbler. — Quite a 

 common breeder throughout, nesting in second growth either in the valleys 

 or in clearings on the mountains. Mr. Harrower has taken several sets of 

 eggs about June 1, near State College. 



70. Dendroica fusca. Blackbxjrnian Warbler. — Scarce summer 

 resident in the more extensive hemlock patches in the mountains. 



71. Dendroica virens. Black-throated Green Warbler. — Abun- 

 dant summer resident wherever patches of coniferous timber occur in the 

 mountains. It is especially abundant at Stone Valley and Bear Meadows 

 and Mr. Harrower found one nest near Bald Knob in late June, 1911. 



72. Dendroica vigorsi. Pine Warbler. — Fairly common summer 

 resident in patches of pitch, Table Mountain and white pine in the moun- 

 tains and valleys. 



73. Seiurus aurocapillus. Oven-bird. — Abundant breeder wher- 

 ever there is any woodland, either in the mountains or the valleys. 



74. Seiurus motacilla. Louisiana Water-Thrush. — Abundant 

 breeder at suitable locations in the mountains, being especially common 

 in the bottom land of Laurel Run, Stone Valley. Here I have taken several 

 sets of three and four eggs and Mr. Harrower has taken a set of five. My 

 earhest date is for four eggs, taken May 14, 1910, and incubated one week. 



75. Geothlypis trichas trichas. Maryland Yellow-throat. — 

 Common summer resident in swampy clearings and damp undergrowth 

 throughout the country. It is not found in the heavy timber. 



76. Icteria virens virens. Yellow-breasted Chat. — Rare summer 

 resident in clearings and second growth thickets. One set of four incubated 

 eggs was collected on June 3, 1910, in Stone Valley. 



77. Wilsonia citrina. Hooded Warbler. — Abundant summer resi- 

 dent in the thickets of rhododendron and laurel throughout the mountain 

 bottomlands. It is very common in Stone Valley and breeds as near to 

 State College as Shingletown Gap where several broods of young have been 

 observed. 



78. Wilsonia canadensis. Canada Warbler. — Quite common 

 breeder in the same localities as the Hooded Warbler inhabits. July 1, 

 1911, I found a nest of this bird near Bald Knob with four full fledged 

 young and at the same place, June 7, 1912, took a set of 5 far incubated eggs. 



79. Dumetella carolinensis. Catbird. — Common summer resident 

 throughout the open country, in thickets and second growth. 



. May 22, 1909. Four fresh eggs. 



80. Toxostoma rufum rufum. Brown Thrasher. — Rather scarce 

 breeder, inhabiting the same localities as the Catbird. 



81. Troglodytes aedon aedon. House Wren. — An abundant 

 summer resident throughout the valleys, nesting most frequently in old 

 orchards or about houses. The usual time for complete sets is about 

 June 1. 



82. Sitta carolinensis carolinensis. White-breasted Nuthatch. 

 — An abundant breeder in nearly all the forested portions and woodlots.
