The Night Warblers

Passerine Migration

Most birds cannot cover the distance between their breeding and winter quarters in one hop. They have to make multiple flights alternated with stopovers. Which factors govern the birds’ decisions to stop, to stop for how long, when to resume flight? What is better – to accumulate much fuel and to make long flights for many hundreds of kilometres, or to travel in small steps? Is it necessary to find habitats similar to the breeding ones or other habitats would do? Are long migratory flights indeed so costly energetically as usually assumed? This monograph summarizes our current knowledge on the ecology of songbird migrants during migratory stopovers and on their behaviour.​

Chasing Warblers

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.
