I watched an unusual behaviour today by some Black-winged Stilts. I don't know why they were behaving the way they were, maybe it is mating season, or maybe they were just mucking around, but I haven't witnessed this sort of behaviour at any time previously. There was a lot of squawking involved, and quite a few times some of them were dunked underwater.
"You are mine!"
"I always wanted to be a bird of prey!"
"I'll stand the mark, you watch the goal umpire!"
"You need a dip!"
"1 against two, not fair!"
"I'm coming to help!"
