I remember walking the boardwalk of Atlantic City when I was very young. My grandfather (a farmer) asked me if I wanted to "see something". Sure, I said.

The next thing I knew, he had grabbed a seagull by both feet with one hand and it was flapping it's wings wildly and squawking into my terrified face.

So I'd imagine that after a few weeks at sea and actually depending on catching birds/fish by hand for survival that one could do so.
