Calurus is a male Western Red-tailed Hawk who weighs about 2 1/2 pounds and has a wingspan of 4 feet. He got caught in a barbed wire fence in California in 1992. He had broken his left wing and it failed to heal properly so he is now unable to fly. He was an adult when he was injured so we believe he was hatched in 1990, if not earlier. Calurus was named for the subspecies of Western Red-tailed Hawks, Buteo jamaicensis calurus.
