Referenced during discussion about condor conservation and captive breeding programs. The speaker mentions: 'It was in Matheson's book America's what was it called Wildlife in America. I read it, but I don't remember it.' The book was being cited regarding Audubon's position on collecting birds for captive breeding programs.

Referenced in discussion about DDT's effects on raptors and bald eagles. The speaker asks 'What was the thing called silent spring and all that?' in the context of discussing what was done to save the bald eagle and the role of DDT/DDE in causing eggshell thinning. Rachel Carson's name is mentioned later in the same discussion as being analogous to Bell Rose's role in the lead shot ban conversation.
