Distribution. This noble falcon is found throughout the United 

 States and breeds from North Carolina and Mexico north to the Arctic 

 coasts. It prefers the mountainous districts, occurring in New York along 

 the Palisades, the Highlands, and the Adirondacks. Undoubtedly it is 

 much more generally distributed than is commonly known, its seclusive 

 habits and custom of traveling long distances on its foraging excursions 

 often concealing the location of its home, or even the fact of its residence, 

 from people who live in the immediate vicinity. Several pairs are known 

 to nest in the Palisades and Highlands. I have found its eyrie on a 

 spur of Mt Colvin overlooking the Lower Ausable lake where the guides 

 of the Adirondack Mountain Reserve have known of its nesting for many 

 years; also in a deep gorge near the Massachusetts line in Columbia county;
