Bruce Haak, a professional wildlife biologist, has been an impassioned falconer for over thirty years. He acquired his first raptor, a kestrel, in 1963 and has never looked back. He did his thesis for his M.S. in Wildlife Science on the foraging ecology of prairie falcons in northern California and conducted field studies on prairie falcons, peregrines, and other raptors, as well as waterfowl and band-tailed pigeons.
