﻿332 Mr. E. Hartert on the Birds of 



mens from Bonaire are — total length about 10 inches, 

 wing 5-5 to 5*8 (average 5 - 6), tail 5 to 5*5, culmen 09 to 

 1*06 ; while those of C. pertinax from Curacao are — total 

 length about 10 inches, wing 5*4 to 5 - 7, tail 4*7 to 5*6, 

 culmen 0'83 to 0'95. 



Having said so much about the Parrakeet of Bonaire, I 

 must add that it is extremely common and numerous in almost 

 every place in the island where the country is not quite bare. 

 The screaming of these lovely birds is about the commonest 

 noise that is heard in the bush on Bonaire, but they are often 

 rather shy. The yellow head of the adult is so clearly 

 visible that even a geological traveller like Professor Martin 

 noticed it, and has distinctly said that the bird is of a species 

 different from C. pertinax. 



Whether ornithologists are inclined to call it a species or 

 a subspecies matters little, but it is certainly different from 

 the Conurus of Curacao.

See above, p. 321. Very rare on Bonaire. 



18. PoLYBORUS CHERIWAY (JaCq.). 



Occurs everywhere, but not in large numbers. These birds 

 are often killed because they are supposed to destroy the 

 chickens. Besides the preceding species, I conclude from the 

 reports of the inhabitants that several other birds of prey, 

 and among these Falco peregrinus and Pandion haliaetus, 

 visit this island, as well as Aruba and Curacao, in the 

 winter. 



There appear to be no Owls in Bonaire. 



19. COLUMBA GYMNOPHTHALMA, Temm. 



Very common.
