Now available: our completely updated course called Ornithology: Comprehensive Bird Biology. This replaces the Home Study Course in Bird Biology which has been offered for the past 40 years. The course uses the new 3rd edition of the Handbook of Bird Biology, with thoroughly revised text, the latest scientific information, and published in full color.
