Birds will also play jokes.

Example: A bird may call your attention to a near-empty water dish. You fill it up. The bird uses bathing behavior to splash you with the water, and then mimics human laughter.

But birds are also not very sophisticated as comedians. Sometimes their funny prank is indistinguishably similar to a nasty trick. But really, if the bird wanted to be mean, he'd just pretend to be chill, and then bite you in the webbing between your fingers. They do that sometimes, too.

Reminds me of Larry Niven's descriptions of Dolphin jokes in his Known Space series.
