 Eagles are usually found near the water where fish may 

 be obtained either on the shore or from the Osprey. The 

 call of the male is a human-like, loud, clear cac-cac-cac; 

 that of the female is said to be more harsh and often 

 broken. Eagles nest in tall trees and on cliffs, and lay 

 two or three dull white eggs, in Florida, in November 

 and December; in Maine, in April.

 a slate-colored race, and the White Gyrfalcon (F. islandus) are 

 also rare winter visitants to the northern United States.

 under exceptionally favorable conditions, authentic records 

 of their visits can be based only on the actual capture of 

 specimens.
