I live in Oregon and the main hawk we see is the Redtailed Hawk. I'm letting our hens free range our small, fenced back yard when I'm home. Even though we are urban I've been surprised at the amount of hawks seen flying above in the last few months that I've had chickens and therefore care to notice such things. How exactly do they hunt, or rather, come in for the kill, when I've seen them they've been flying in large lazy circles way up high. When they find prey they want do they start circling lower and lower? Do they swoop down from their circling? Or are they more likely to find something like a tree to perch in before diving down? I'm just curious as to the nature of their hunting skills and so far from the YouTube videos I've watched on it and other info I've read my specific question hasn't been answered.
