I get it. Phones can only do so much with wildlife shots unless conditions are perfect. I zoomed in on the 1st two pics and going with Northern Harrier because tail is longer with what looks like 5-6 thicker, dark bands and the white part of the feather near the rump. In flight, Harriers have a distinct white patch at the top of the tail, but it is hard to see from the side. An adult gray color phase is also common, and they are generally the same height as red-tailed but a little more slender in appearance.
While the dark immature red-tailed Hawks are similar in color and front markings the tail has a shorter appearance and 10+ thin bands with little more, if anyone white near the rump.
