Regional field guides & checklists: 1964-2009

Thomas R. Dunlap’s excellent In the Field, among the Feathered: a History of Birders and Their Guides (Oxford University Press, 2011) describes how bird guides gradually improved over time. One important innovation was the development of place- or region-specific guides and checklists.

In this post, I note 7 such guides and checklists with an eye on the California condor.

In between the reviews I show some photographs and diagrams from the report (note the shadows!).
