The Home Study Course in Bird Biology using the 2nd edition of the Handbook of Bird Biology is no longer being sold. An updated course, Ornithology: Comprehensive Bird Biology, took its place in September 2016. The new course will follow the completely revised 3rd edition of the Handbook of Bird Biology. The text has been thoroughly revised, updated, and published in full color.
The Handbook of Bird Biology, 2nd edition, the required text for the old version of the Home Study Course in Bird Biology, is currently out of print and we have no more copies to sell. We will continue to support Home Study Course in Bird Biology using the 2nd edition for the near future. Anyone who has already purchased and started the course will be allowed to finish.
