Robert Mulvihill, a National Aviary ornithologist, developed an early interest in bird watching in his native Pittsburgh. He began his career at the Carnegie Museum of Natural History's Powdermill Nature Reserve, which operates a world-renowned bird-banding program. He has authored more than 30 scientific articles on ornithology and written dozens of popular articles about birds and nature. He was the statewide coordinator and co-editor of the Second Atlas of Breeding Birds in Pennsylvania. He has received awards for outstanding bird conservation efforts from the Audubon Society of Western Pennsylvania and the Pennsylvania Society for Ornithology. Mulvihill and his wife, Pam, a librarian, live happily in Pleasant Hills with three rescue beagles—Rascal, Rooby, and Shiloh—and one rescue indoor cat, Smudge. (Photo by Jim Ralston)
