I will never forget watching a kookaburra swoop down as my grandmother went to take a bite out of a bacon sandwich, and stealing a piece of bacon out of it without touching her or the bread. It then sat on a branch whacking the bacon against it to "kill it" before eating it.
Same with me, but I was camping as a kid. One took the snag out of my mates bread just as he was about to bite it. It made sure it was dead by hitting it on the tree it landed in.
