"I am very impressed by Bob and Vera Thornton's book. The photos are excellent.... I am especially impressed by the enthusiasm they bring to their subject." -Victor Emanuel, President, Victor Emanuel Nature Tours Known to many as "the butterflies of the bird world," wood warblers allure even the most experienced and discriminating birders. Their annual migrations to and from nesting areas in the United States and Canada draw thousands of birders to places such as High Island, Texas; Crane Creek, Ohio; and Point Pelee, Ontario, where warblers stop to rest and feed during the long journey. There birders have a chance to see and photograph these colorful, elusive songbirds whose quick, darting flight among high branches and thick cover makes them some of the most challenging birds to observe and identify. In this entertaining, beautifully illustrated book, Bob Thornton recounts his and Vera Thornton's cross-continent adventures in finding and photographing all 52 species of wood warblers that nest in the United States. In addition to describing where and how they photographed each species, Thornton tells marvelous stories of the colorful characters they encountered along the way. He also touches on the current human threats to wood warblers that come from loss of habitat.
