SUMMER BIRDS. 
1 68 
Note. — As to the occurrence of other water-birds in the Catskills 
we can only speculate. Mr. Burroughs speaks* of meeting with a 
brood of Hooded Mergansers ( Lophodytes cucullatus Reich.) at the 
junction of the Beaverkill — east branch — with the Delaware River, 
and our other Mergansers have been recorded as breeding still farther 
south in the Alleghanies. Nuttall narrates j* the discovery ol a brood 
of the Common Sheldrake ( Mergus merganser Americanus Ridgw.), 
on the Susquehanna River, in Pennsylvania, and both this species 
and the Red-breasted Merganser (. Mergus serrator L.) have been 
recorded by the Bairds J as breeding in Perry County, in the same 
State Undoubtedly others of the Anatidae than those which have 
been mentioned occur in the Catskills. It also seems likely that the 
Pied-billed Dabchick ( Podilymbus pod i ceps Lawr.) may breed at some 
of the small lakes, but it was not found by my brothers, by whom 
several of the lakes were visited, and Mr. Burroughs writes me that 
this bird as well as the Great Northern Diver ( Colymbus torquatus 
Briinn.) he has failed to meet with on the waters ol the Catskill 
region.
