When I began my study of old publications about birds, I noted that numbers often accompanied the scientific and/or vernacular species names of bird species.

In 1953, the National Audubon Society published its Research Report No. 4. Titled The California Condor and written by Carl B. Koford, this book was the 1st detailed scientific study of Gymnogyps californianus.
This post is not about the contents of Koford’s report. Rather, I provide selections from published reviews of the report. These reviews make plain the significance of Koford’s research and provide a sense of how experts responded to Koford’s findings.
In between the reviews I show some photographs and diagrams from the report (note the shadows!).

Protecting the California condor from extinction is about biology, right?
That is true only if you consider mathematics to be an essential part of biology.
This post notes 3 older examples of insights provided by mathematics into the plight of the California condor. These examples all date from the time when the condor’s future was especially bleak.

In 1981, the Santa Clara Valley Audubon Society held a conference concerning the California condor. A transcript was published the next year. However, this document is not currently in a library (at least a library that is part of the WorldCat network).
As I have an original copy of the conference proceedings, here are some details about the conference and excerpts from the presentations and discussions.
