FIELD NOTES LOCATION: Alcatraz Island, San Francisco Bay, Calif. DATE: April 19, 1985 Doug Bell WEATHER: Clear, sunny. Temp. ~ 50's. Light wind. HABITAT: Rocky Island, old prison grounds.

He was in US Coast Guard, did work for Bureau of Land Reclamation in Wyoming where they surveyed Prairie Falcons and Bald Eagles, and came to Calif. on present job in 1980. He has a Masters from Arizona.
