Since it was a fishing boat, they probably had some nice barbed fishing hooks around. You can catch birds relatively easily with baited fish hooks. The birds take a bite, and you hook up pretty quickly. Of course, it's an ugly scene at that point, but, easy to get a few birds that way in a survival situation. I have "caught" birds by accident while casting into fish breaking the surface. The birds were diving on the bait being driven to the surface by the fish I was trying to catch. My surface popper looked like a tasty treat to a hungry gull... I'm glad my wife wasn't on the boat to see the scene as my son and I tried to get the hook out without killing the rather upset bird. <img src="/images/graemlins/shocked.gif" alt="" />
In any case, I think in a survival situation, I think your odds catching birds using a fish hook that was baited with something might be better than catching fish!
