WHITE-HEADED DOVE, OR PIGEON. 
Coluhba leucocephala, Linn . 
PLATE CCLXXX.— Male and Female. 
The White-headed Pigeon arrives on the Southern Keys of the Floridas, 
from the Island of Cuba, about the 20th of April, sometimes not until the 
1st of May, for the purpose of residing there for a season, and rearing its 
young. On the 30th of April, I shot several immediately after their arrival 
from across the Gulf Stream. I saw them as they approached the shore.
