6. Cory on the Birds of the Leeward Islands. 



[The Birds of the Leeward Islands, Caribbean Sea. By Oharles B. 

 Cory, Curator of Department of Zoology: Field Mus. Nat. Hist. Publ. 

 No. 157. ( >rn. Ser. Vol. i. No. 5, Chicago, 1909.] 



With the assistance of his colleagues at the Field 

 Museum, Chicago, Mr. Charles B. Cory, who has laboured 

 so long and so well on the ornithology of the Antilles, has 

 been able to prepare an excellent summary of the present 

 state of our knowledge of the birds of the Leeward Islands. 

 Under this designation are included the islands called 

 Aruba, Curacao, Bonaire, Islas de Aves, Los Roques, 

 Orcliilla, Tortuga, Blanquilla, Los Hermanos, Testigos, and 

 Margarita. Besides the specimens obtained by the two 

 expeditions sent out by the Field Museum, other species 

 previously recorded from these islands have been included in 

 the list. 



The islands are taken one by one, and after a short 

 introduction and a notice of previous authorities, a list of 

 species recorded as found on each is given. The islands lie 

 along the north coast o£ Venezuela, and the birds are nearly 

 all Venezuelan in form, although they have, in some cases, 

 become sufficiently differentiated to require (according to 

 the prevailing fashion) subspecific names. Mr. Cory now 

 gives such names to Dcndrceca ruficapilla ubscura (Los 

 Roques); Conurui aruginosus tortiigemis, Tiaris tortugensis, 

 and Ccertbu ferryi (Tortuga) ; Holoquiscalns orchillemis 

 (Orchilla) ; Conurus neuxenus and Platycichla venezuelensis 

 atra (Margarita). 



As we have said, the birds of the Leeward group 

 are all Venezuelan or slightly modified Venezuelan forms, 

 the only characteristic Autillean form met with there being 

 Margarops fuscatus, which is "common in the gardens" on 

 Bonaire. 



A table of the species and subspecies, shewing their 

 exact distribution, of the Leeward-Islands Birds is a useful 

 addition to this memoir, and an outline map gives the 

 exact position of the various islands.
