He was a contributing editor of Birder's World magazine, culminating with an article about American Crow behavior observations of his own, plus his own watercolors of crows performing the behaviors in the text. He died with the wish of revising his 1980 Audubon Encyclopedia of North American Birds, about which Roger Tory Peterson said never left his desk side. Birder's World published, before the crow article, a story about him, with a photograph of him at the University of North Carolina—Chapel Hill biological station, with much concentration examining a specimen.
