this was really great, i'm glad you posted this. the bit about the red knot buffered something I saw on PBS once. i've been trying to find the episode for the last ten minutes, but no luck. anyway, it was a mynah bird that lived with some dogs. the bird knew that when the dogs heard a certain noise outside, they went nuts and ran out the doggie door, barking their heads off. so the mynah would imitate the noise as a prank and successfully set them off. but get this: the mynah would laugh at them. i was skeptical when the owners said that, but they filmed the whole bit and I'll be damned if that bird wasn't laughing at those dogs.
