Have you ever watched sibling butcher birds play fight and other stuff? They throw themselves on their backs and submit to pecks, feather pulling and being pinned down! It's hilarious
. Magpies do it too but not as often. The funniest bird to watch is the "dominant" rainbow lorikeet. He (or she, never been able to tell male from female, anyone know the difference?) literally throws his weight around - when he waddles from side to side, much like John Wayne did in his gun toting days! Their squabbles are very funny, especially when hanging upside on the bird feeder 'cos there's not enough room on top!
Mmm, I think pelicans are the most graceful flyers.
Sorry about your budgie.
