Things have been humming lately for Dr. Anil Sain, M.D.The Manteca physician — who has captured images of big cats in the jungles – took aim at smaller prey photographing humming birds during a British Columbia workshop at the secluded Bull River Guest Ranch in the Canadian Rockies.His large mounted color photographs are on display in his office hallway between his patients’ exam rooms to view and enjoy along with the flowers and big cats he has photographed in past years. Sain flew to Kalispell, Montana and rented a car that took him 130 miles to the Cranbrook, British Columbia. There he joined nature photographers John Gerlach and Scott Bechtel with some nine other photographers from around the country to photograph several species of the tiny birds that return every year in May and June.
