Hawk vs Eagle

Mitchell Nussbaum, a Central Park nature observer and amateur astronomer, sent me the photo below with a note:

Dear Marie, From Ft. Tryon park last Wednesday at 10:53AM the Redtail made a sortie at the Eagle. What a huge difference in size! Imaged from the Billings Lawn, looking West
