In the southern part of the breeding range the time of nesting is 

 variable. Gundlach found eggs in Cuba through all the months 

 from September to January. Eggs were taken on the Galapagos 

 September 2, 1897 (Rothschild and Hartert). The young found 

 February 5, 1910, at Upper Matecumbe Key, Fla. (Brodhead), 

 were hatched from eggs that must have been laid in December, while 

 at Charleston, S. C, Wayne says that the earliest eggs are deposited 

 the middle of March and that eggs are most common in late March. 

 Young were in the nest May 25, 1875, at Cobb Island, Va. (Bailey) ;
