18 PROCEEDINGS OF THE 



52. Compsolhlypis americana usnese. Parula Warbler. — Com- 

 mon at Tamarack Swamp, but less plentiful in Potter county, 

 where it was seen several times at Galeton and sparingly in the 

 Kettle Creek region. 



53. Dendroica mstiva. Yellow Warbler. — Rare. Seen only 

 occasionally in the open country. 



54. Dendroica casndescens. Black-throated Blue Warbler. — 

 Very abundant, both at Tamarack and in Potter county where- 

 ever the hemlocks remained uncut. Perhaps the most abun- 

 dant Warbler in the forests around Oleona. 



55. Dendroica macidosa. Magnolia Warbler. — This species 

 was even more abundant at Tamarack Swamp than the preced- 

 ing. Indeed in those portions of the Swamp where the hem- 

 lock predominated among the coniferous trees, it might almost 

 be said to swarm, many adult birds with food in their bills 

 being observed. 



56. Dendroica pensylvanica. Chestnut-sided Warbler.— Not 

 found in Tamarack Swamp or in the forest region of the Kettle 

 Creek Valley, but observed at Galeton, and wherever there was 

 second growth timber. 



57. Dendroica blackburnias. Blackburnian Warbler — Abun- 

 dant, both at Tamarack and around Oleona, but always, like 

 the other northern Warblers, confined to the primeval forest. 



58. Dendroica virens. Black-throated Green Warbler. — Not 

 so plentiful as D. cserulescens, maculosa or blackburnix, but still 

 tolerably common in the deep woodland. 



59. Seiurm aurocapillus. Oven-bird. — Unusuall}' abundant, 

 both at Tamarack Swamp and along Little Kettle Creek. 



60. Seiuriis noveboracensis. Water Thrush. A single bird with 

 nest and four eggs was found near Oleona, June 26. The 

 nest was beautifully situated among the roots of a large beech 

 tree on the banks of what, in spring, must be a beautiful little 

 mountain torrent, and although it was not collected, I feel no 

 doubt of the identitj\ Indeed this whole locality was admir- 

 ably suited to the habits of this bird, and doubtless a more 

 thorough seaich would have revealed it as not an uncommon 

 breeder. 



61. Geothlypis Philadelphia. Mourning Warbler. — Not ob-
