It is a matter of satisfaction to record that this magnificent 

 and entirely harmless bird is fairly common in this County. 

 I have observed examples on the Hudson River in close 

 proximity to Albany, and over the Normanskill near Kenwood 

 on nearly all of my outings in those directions. I have not 

 yet located a nest in this County, though in the height of the 

 breeding season of 1904 I found three adults in a wild spot 

 known locally as "Hell Hole," in Rensselaer County, about 

 four miles south of tiie city of Rensselaer and but a short 

 distance from the Hudson River, whose actions indicated that 

 I was close to an eyrie. One of these Ospreys had in its 

 talons a large fish, which it had just caught in the river. My 

 efforts to locate the nest were unsuccessful, but I have no 

 doubt that it was near at hand. Two of the birds flew low, 

 uttering the while their peculiar flute-hke cries, which often 

 resembled the warbling of lesser birds. The amateur has no 

 difficulty in identifying the Osprey, the pure white under parts
