Eeeeek! Imagine the scene - in the park taking pictures of the geese and the ducks and the squirrels. Oh, that one's quite close.... I'll just get a bit closer... I guess it thought that I had bread or something!
Nasty! I had something like that happen to me. I as quite happily eating lunch (of the sandwich variety) near the local pond, and a duck tried to take it out of my hand! Nethertheless, i didn't eat the rest of it andgave it to the rogue duck!
