I have an anecdote of strange Peregrine behavior you might be
interested in. I was hiking the sand spit and heard a bird screaming. I
saw a Peregrine on the ground about a foot away from a Marbled Godwit.
The Peregrine was screaming at the Godwit, but they both just stood
there eyeing each other. After a few minutes the Peregrine flew away,
and a few minutes after that, the Godwit flew off.
I wasn't sure if the falcon needed the godwit to fly so it could kill
it. Do they take prey from the ground?
