While hiking in the lower part of Embudito Canyon on the edge of Albuquerque, NM today (June 28, 2021), I came across a large hawk perched just off the trail in plain sight. I couldn't determine if it was a Red-tailed or a Swainson's. Looked to be an immature either way. I have attached a couple of grainy photos (best I could manage). As one can see, it's rather white on the front and head while largely brown, albeit mottled with white, on the back. Other info not readily apparent in the photos: thick subterminal band on the tail with three or four thinner bands above it; yellow tarsi and toes; yellow cere; yellow eyes; mostly white head with a bit of brown on top; and, maybe a bit of a belly band. Definitive answer anyone? And why?
