Photography has been a lifetime hobby and my interest has always been nature subjects. In recent years this interest has focused on birds, particularly birds in flight. In this fascinating endeavor I spend many hours stalking and photographing marsh and shore birds and birds of prey. My usual haunts are the South San Francisco Bay, particularly the area near the Palo Alto Baylands Nature Interpretive Center, and the coastal shore and beach areas of San Mateo, Santa Cruz and Monterey counties.
