MARYLAND GEOLOGICAL SURVEY 305 



Dendroica blackburniae. BLACKBURNIAN WARBLER. Rather com- 

 mon in the hemlocks about Finzel. I saw one near Bittinger on 

 June 30 and took one on Dans Mountain, near Rawlings, on July 21. 



Dendroica virens. BLACK-THROATED GREEN WARBLER, A female 

 was seen at Finzel on June 18. 



Dendroica discolor. PRAIRIE WARBLER. Several were seen in 

 bushy woods at Oldtown July 22-23. 



Seiurus aurocapillus. OVEN-BIRD. A very common species 

 throughout the region. 



Seiurus noveboracensis. WATER-THRUSH. This species was fairly 

 common about Finzel, especially in a swamp between Big and Little 

 Savage Mountains. Nearly every small stream flowing through low 

 woods had a pair or two. A single bird was observed at Swanton. 



Seiurus motacilla. LOUISIANA WATER-THRUSH. Though normally 

 affecting low altitudes, this species frequently follows small streams 

 up to their source. One was thus observed near Finzel along a brook 

 flowing through a dense hemlock forest, whose undergrowth of Rhodo- 

 dendron and Kalmia also afforded a congenial shelter to 8. novebora- 

 censis. Several were seen along Crabtree Run, near Swanton, and 

 I took a specimen on Dans Mountain July 21. 



Geothlypis trichas. MARYLAND YELLOW-THROAT. Noted in rather 

 small numbers at Finzel, Grantsville, Mountain Lake Park, Rawlings, 

 Oldtown and Little Orleans. 



Icteria virens. YELLOW-BREASTED CHAT. A pair or two noted in 

 the vicinity of Finzel. It was rather common about Mountain Lake 

 Park, Swanton, Rawlings, Oldtown, and Little Orleans. 



Wilsonia mitrata. WILSON'S WARBLER. In thickets of young 

 growth on the lower slopes of Dans Mountain, near Rawlings, this 

 species was rather common. 



Wilsonia canadensis. CANADIAN WARBLER. This was the most 

 abundant warbler at Finzel, where old birds were seen feeding young 

 just from the nest about June 20. The species was rather common 

 in the rhododendrons, which abounded in favorable situations in the 

 valley of the Castleman near Grantsville. It was also rather com- 

 mon about Swanton.
