BIRDS 



44. Tiaris bicolor (Linne). — Forms of this species occur throughout the 

 West Indies, even reaching the coast of South America and the islands of Cura- 

 goa, Aruba and Bonaire. The Bahama bird has probably reached the Islands 

 by way of Haiti, as it appears to be of only accidental occurrence in Cuba and 

 Florida.
