Out for a ride today in southern Louisiana and spotted 4 hawks, two of which I believe to be red-tailed, but the other two have me puzzled. They both were in open field areas - white chest and dark, almost black back and wings. I did not see any streaking on the belly area of either of these hawks. Didn't see any red or brown on them either. Of course, a picture would be nice, but I don't have that to offer. By the way, they were seen about 20 miles apart. Any thoughts on ID?
