The long awaited, newly revised, 7th edition of P.D. Skaar’s Montana Bird Distribution is available. This book is an excellent companion to field guides because it indicates where birds are found in Montana. It is a book of maps: for all of Montana's 427 bird species observed in the state, maps show breeding and wintering areas.
Eighteen birds are new to the new edition: Cackling Goose (a split from Canada Goose), Tufted Duck, Manx Shearwater, Glossy Ibis, White-tailed Kite, Crested Caracara, Ross’s Gull, Iceland Gull, Lesser Black-backed Gull, Long-billed Murrelet (a split from Ancient Murrelet), Inca Dove, Carolina Wren, Pacific Wren (a split from Winter Wren), Curve-billed Thrasher, Siberian Accentor, Blue-winged Warbler, Eastern Towhee, and Eastern Meadowlark.
This book is a useful reference. In addition to bird distribution maps, the book lists which species are threatened, endangered, and sensitive.
Montana Bird Distribution was first published by P.D. Skaar in 1975. The 7th edition is a cooperative project between Montana Audubon, the Montana Natural Heritage Program, Montana Fish, Wildlife & Parks, and the Montana Bird Records Committee. The 7th edition was published in June 2012.
