Cory's 'the Birds of the Leeward Islands'

ince of Manitoba, the former numbering 59 species, and the latter 268 species and 5 additional subspecies.Both lists are very carefully annotated and throw much light on the ranges and nmnner of occurrence of the mammals and birds in Man.itoba.They are thus welcome and valuable contributions to faunal literature.Here and there, mostly in the technical names, a few typographical errors nmr the otherwise excellent appearance of the paper.Manitoba, about 250 miles square in area, is faunally partly Canadian and partly Alleghanian; "a line drawn from the southeast corner to the northwest corner," says the author, "would nearly demark these zones."As usual in all local bird lists of these days, the former abundance of many species, in comparison with their present scarcity, is noted.Thus the statements: "Formerly common and breeding; now nearly extinct"; "much less common than formerly," etc., after many of the species of wild fowl form a sad record of the passing away of species once apparently in no danger of extirpation.On the other hand, the Prairie Hen, almost unknown in Manitoba in 1882, has since "spread with cultivation, and is now abundant in all the settled parts" of the Province.A similar increase in extent of range and numbers is •oted for the Mourning Dove, Burrowing Owl, and the unwelcome English Sparrow.In this connection attention should be called to Mr. Seton's great work on the Mammals of Manitoba, just issued in two sumptuous royal octavo volumes, 1 with over 1300 pages of text, 100 plates, 68 maps, and several hundred text illustrations, the outcome of many years' observations.The ornithologist wfil be especially interested in the part treating of the faunal zones of not only Manitoba but of North America at large, with the accompanying full-page faunal map.There is naturally many incidental references to birds in the work; besides, there are few ornithologists who have not a strong interest in the life histories of mammals as well as birds.--J. A. A. Cory's 'The Birds of the Leeward Islands.' 2--This is (1)a summary of the ornithological results of two expeditions to the Leeward Islands for the Field Museum and (2) a list of the birds previously recorded from these islands, which include Arubu, Cura9ao, Bonaire, Islas de Aves, Los Roques, Orchilla, Blanquilla, Los Hermanos, Testigos, and Margarita.Each of these islands is treated separately, its geographic position, extent, and character being stated, followed by its ornithological bibliography, and a list of the birds known to occur there, with a reference to the specimens taken by the Field Museum expeditions.These lists are summarized in a • Life Histories of Northern Animals: An Account of the Mammals of }Ianitoba.Charles Scribner's Sons, New York, 1909.Two volumes, roy.8vo.$18.00 net per set.
