Birds of Prey
My interest in raptors originated from a misspent youth (during grad school), hunting with hawks in England. I took a falconry course from mentor, Nick Fox in the 1983. I flew all sorts, but eventually found my niche with European sparrowhawks, chasing starlings, blackbirds, and moorhens across lowland habitats. I was impressed with how my sparrowhawks used different tactics for chasing particular prey, largely based on initial successes and failures. I was amazed how some (but not all) hawks learned to outsmart prey by approaching from behind hedgerows or natural contours (see the BBC video). Each bird had a unique, measureable personality. This led to a growing interest in describing how raptors are distributed in relation to their habitat and food supply.
Keen birders that explore Humboldt County’s habitats see a variety of birds of prey, including peregrine falcons, merlins, American kestrels, northern harriers, white-tailed kites, osprey, sharp-shinned hawks, Cooper’s hawks, red-tailed hawks, red-shouldered hawks, ruff-legged hawks, bald eagles, golden eagles, and of course turkey vultures. Several owl species also occur locally, including short-eared owls, barred owls, spotted owls, great horned owls, and barn owls.
I’ve had the pleasure of working with four graduate students on bird of prey projects.
