I believe this is a mature male Cooper's Hawk that landed on my neighbor's front railing and had no problem with me snapping his picture over and over again. In fact he looked to be posing for me! He then flew down to our front lawn and paraded around like a runway model. He must have been practicing for attracting a mate. It's great when you're stuck at home and can't travel, to photograph the wildlife, that they come to you! 4/18/2020
(Many thanks to Scott and family for spotting this guy on their railing and pointing him out!)
