This companion to a new PBS series featuring renowned wildlife documentary host Sir David Attenborough is not as feature-rich as some comparable sites but deserves a visit nonetheless. Essentially a collection of five thoughtful illustrated essays, the site explores bird evolution, intelligence, songs (with RealPlayer examples), parenting, and several superlative birds. Additional contents include classroom resources (currently only two lessons), an essay on the making of the series, and a selection of annotated online resources.
