John Bielefeldt (1945–2011) was a Wisconsin native and received a B.Sc. from the University of Wisconsin at Madison. He worked as a free-lance editor and as a biologist in park planning for county government at Racine, Wisconsin. He studied biogeographic effects and avian habitat use in conifer plantations, conducted multi-year research on the Acadian Flycatcher and Hooded Warbler in southeastern Wisconsin, and conducted field studies with RNR for over 30 years on Wisconsin's breeding Cooper's Hawks. His multi-decadal service on behalf of the Wisconsin Society for Ornithology eared him their prestigious Silver Passenger Pigeon Award (1988).
