Songbird Journeys: Four Seasons in the Lives of Migratory Birds

Each spring, millions of orioles, tanagers, thrushes, warblers and other songbirds travel thousands of miles from the tropics to their summer breeding grounds as far north as the boreal forests of Canada and in the fall return to their southern wintering grounds. Navigating by the stars, magnetic fields and polarized light patterns invisible to humans, the birds make their amazing journeys at night, flying in huge flocks that most of us never see. In this captivating debut, Chu, an ornithologist at Cornell, conveys the wonder of these migrations, following the birds through all four seasons and chronicling the efforts of scientists to track them with technology and their own ingenuity—trekking to distant locales, some even following, in cars and airplanes, individual birds outfitted with transmitters. Their heroic efforts are important, Chu points out, for only by understanding where the birds go can we learn how to preserve their habitats. To engage the general public in these efforts, she includes information on the best places to observe migrating birds and provides lists of citizen-science projects and resources for amateurs birders who want to contribute to the growing base of knowledge about bird migration. 8 pages of color illus. not seen by PW .
