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.

The headline “Rare Condor’s Fall from the Sky Remains a Puzzle” appears in the Fresno Bee newspaper for 26 May 1965. The article explains:

Here’s the story, as told in a government report and other publications.

The factors responsible for the near extinction of the California condor have been debated since the 19th century. Today, the factor considered the greatest threat to condors is the use of lead ammunition by hunters. Condors may be poisoned by lead when they consume “gut piles”, the entrails of deer and other game left behind by hunters.
Among the many other threats to condors that have been reported through the years are the poisons employed to kill agricultural pests and the shooting of condors for their feathers. This has led to defensiveness by trade organizations associated with these activities.
