Harrison (Bud) Tordoff, an ornithologist and former head of the Bell Museum of Natural History whose efforts to establish peregrines in downtown Minneapolis was admired by office tower workers for years, died on July 23 in St. Paul.
He suffered from Alzheimer's disease.
The World War II ace fighter pilot was 85.
"He was the heart and soul" of the peregrine recovery project, said Pat Redig, founder and former director of the Raptor Center at the University of Minnesota.
"He had the vision, and made the community connections to make it go," said Redig. "That, with his unbounded love for the peregrine itself, is what really carried the project."
By 1982, the project was firmly established by Tordoff, Redig and others when funds became available from the Minnesota Department of Natural Resources' Nongame Program.
Over time, the Midwest Peregrine Society of the University of Minnesota's Bell Natural History Museum would work on recovery in nine states, including Minnesota.
After the peregrine was removed from the endangered species list in 1999, Tordoff continued to help in the regular monitoring of their condition.
