6. Cory on the Birds of the Leeward Islands. 
[The Birds of the Leeward Islands, Caribbean Sea. By Charles B. 
Cory, Curator of Department of Zoology. Field Mus. Nat. Hist. Publ. 
No. 157. Orn. 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, Cura 9 ao, Bonaire, Islas de Aves, Los Roques, 
Orchilla, 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 of 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 Dendroeca rufixapilla obscura (Los 
Roques) ; Conuru * ceruginosus tortugensis, Tiaris tortugensis, 
and Ccereba ferryi (Tortuga) ; Hologuiscalus orchillensis 
(Orchilla) ; Conurus neoxenus 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 Antillean form met with there being 
Margarops fuscatus, which is “ common in the gardens 33 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.
