    Birds of prey have an aura that few other creatures have. In the acclaimed Hawks in Flight, Pete Dunne showed what birds of prey look like. In The Wind Masters, he shows what it is like to be a bird of prey. He takes us inside the lives and minds of all thirty-four species of diurnal raptors found in North America -- hawks, falcons, eagles, vultures, the osprey, and the harrier -- and shows us how each bird sees the world, hunts its prey, finds and courts its mate, rears its young, grows up, grows old, and dies. Vividly written, and beautifully illustrated by David Sibley, The Wind Masters is a brilliant work of narrative natural history in the tradition of Peter Matthiessen's The Wind Birds and Barry Lopez's Of Wolves and Men.
