I think I just watched my keets birdy battle. They locked feet together, were flapping like crazy and there was acking. I couldn’t see clearly what they were doing with their beaks, but some of it looked like beak tugging. It lasted for a minute or two, I tried to stop them but they both ignored me. After they hit the cage floor they both returned to separate(but next to each other) perches and sat there for a minute in silence. After that they went back to kissing and preening. Really weird behavior… have any of your guys birds locked feet and fought befor?
