Two birds flew at high speed evidently head-on right into our bedroom sliders, just next to the woods on our rural property which abutts a 65 acre beaver pond. Sadly, both died in the crash. The larger bird is a falcon that appears to be a 12 inch Merlin probably chasing the small bird - one that I cannot identify. The small bird is med. brownish gray and smooth coated with a brown breast and creamy yellow underbelly that extends down partway onto the tail. Feet and beak are dark, beak is small and straight with a little curve at the end, the bird is 5-6 in. long with a wing-span of 11 in. There are dark markings from beak to eye with a creamy yellow line over the beak and eye. .It has a half inch of bright yellow at the tip of its tail. Both birds appear heathy. I did not see them in flight, but heard the very loud crash yesterday afternoon - didn't find it till this morning.
Can you name the small bird for me? Thanks.
