310 BULLETIN 50, UNITED STATES NATIONAL MUSEUM 



Winters from Florida (near St. Marks, Captiva Island, Sanibel 

 Island, ^Monroe and Volusia Counties, the Florida Keys) ; and southern 

 Mexico (Santa Efigenia) throughout Central America to Colombia; 

 Venezuela; Ecuador; western Brazil (Matto Grosso, Upper Amazonas) ; 

 and to northern and eastern Peru (Chamicuros, Huambo, Maraynioc). 

 Occasional in winter north to New Jersey and southern Illinois, but 

 most "winter" records from the United States are of belated migrants 

 or sick birds, not normal wintering individuals; possibly occasionally 

 migrates to Cuba. 



Casual in Colorado (Seven Falls; Manitou). 



Type locality. — Pennsylvania= Schuylkill River, ex Wilson.
