two yellow and black birds sitting on a branch

displays two small yellow birds with black wings and orange beaks standing on a tree branch. they appear to be agitated, with their beaks open, and start singing aggressively while pointing at each other. as they sing, they become more and more agitated until they begin to attack each other and peck at each other's heads. this intense display of aggression continues until one bird finally backs down and starts to leave. seems to capture a territorial display between two small birds, with a clear winner emerging from the conflict.
