Bud and tweeters -

Any experience re: the original question? I don't see that a
peregrine would have any trouble carrying a duck a ways. Ducks can
be big, but peregrines are pretty powerful. I had the amazing luck
to see a Gyr take out a green-winged teal and then carry it to an
ice-edge to eat on Cayuga Lake, NY. The duck was nothing to the Gyr.
Addmittedly, a wigeon is bigger than a teal and Peregrine smaller
than Gyr, but small ducks and shorebirds are preferred foods of
Peregrines, correct? I would think a peregrine could carry a wigeon
as far as necessary to eat it.
