I 58 SUMMER BIRDS. 



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 {Lophodytcs cticidlatiis 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 t the discovery of a brood 

 of the Common Sheldrake [Mcrgiis merganser Americamis Ridgw\), 

 on the Susquehanna River, in Pennsylvania, and both this species 

 and the Red-breasted Merganser {Meigiis serrator L.) have been 

 recorded by the Bairds \ as breeding in Perry County, in the same 

 State Undoubtedly others of the Anatida: than those which have 

 been mentioned occur in the Catskills. It also seems likely that the 

 Pied-billed Dabchick [Podilyiubiis podiceps Lawr. ) m.a)' breed at some 

 of the small lakes, but it was not found by my brothers, by whom 

 several of the lakes were visited, and ^Ir. Burroucrhs writes me that 

 this bird as well as the Great Northern Diver ( Colymhis torqiiatiis 

 Briinn.) he has failed to meet with on the waters of the Catskill 

 region.
