Cocoa (CAG) is a dominant bird and also a jealous bird. Most of the time she refused to let Mocha (Hill Mynah) to perch on our shoulders. Cocoa would chase Mocha away. Not only that, she also chased Mocha away from the kitchen cabinet and the fridge.
This morning Mocha followed my wife to the dressing room. He likes to perch on the clothes rack. Cocoa flew in later and perched on the curtain rail at the window. Mocha chased Cocoa away and took over the curtain rail. Cocoa then flew to the door. And again Mocha went to "attack" Cocoa. Cocoa had to flee and she crash landed outside the room. Mocha claimed his 1st victory over a bird almost twice his size.
