Bruce Haak has spent five decades practising falconry and studying wild raptors. A graduate of Oregon State University, Bruce conducted one of the early radio-telemetry studies of the prairie falcon. As a wildlife biologist for the Idaho Department of Fish and Game, he did peregrine reintroduction and population monitoring. For two decades, he bred peregrines for both falconry and reintroduction efforts.
