You often get more variety in October, but the other species add up to a lot less individual hawks than what you see if you get a good Broad-wing day. Broad-wings can come through in groups of thousands at a time. Most of the others tend to be either solitary or come in twos and threes. I've seen a "big" kettle of Red-tails exactly once, in twenty-five years of being involved with hawk counts. IIRC, we ended up with somethng like 69 of them that hour, most of them in a single group.
