One of a pair of hawks. For details on the other individual (a red-shouldered hawk), see https://www.inaturalist.org/observations/135117722
The second photo shows both hawks together. The red-tailed hawk is probably the one on the lower right.
The third (blurry: sorry) photo shows what looks like one hawk taking evasive measures from the other who is giving chase (?).
We first saw this bird on 9/14 in the evening.
