The Migration of North American Birds (1935)
Frederick Charles Lincoln
How does a small bird find its way across a hemisphere? Frederick Lincoln lays out the mystery of migration: the theories of its causes, the ancestral home ideas, photoperiodism, and the timing of the flights. Clear, authoritative, and grounded in real banding data. A fine account of North American bird migration and the science behind it. Chart the great seasonal journeys of the flocks.
Every copy includes a printable PDF edition, a beautifully typeset book you can print, mark up in the margins, and keep on your shelf. Yours the moment you own it.
