Robert Porter Allen

Born 24 Apr 1905; died 28 Jun 1963 at age 58.American author and conservationist recognized for saving the whooping crane from extinction by discovering (1955) the nesting ground of the sole remaining flock near the Arctic Circle. He was a leader in having whooping crane habitats in Texas and Canada proclaimed as refuges. He helped establish a working protective plan for flamingos and recommended methods of saving the small surviving colonies of roseate spoonbills, thus helping to perpetuate the species. His monographs on the whooping crane, the roseate spoonbill, and the American flamingo are the standard authoritative works on these species.[Listen to the whooping crane call]
