Robert Porter Allen was an ornithologist and conservation activist with the National Audubon Society. He founded the Audubon Research Center in Tavernier, FL and dedicated his life to documenting various bird species. His efforts to document the Whooping Crane nesting sites in North America generated national media coverage and aided in the creation of the Endangered Species Act in 1973. This collection features digitized items from the USF Libraries Special Collections holdings.
This portion of the digital collection contains photographs or single-page images from the collection. For papers and warden reports, see the Robert Porter Allen Audubon Collection - Photographs.
