Habits. According to Davison this extraordinary bird is only found in evergreen forests. He writes, " It is a very restless bird flying about from tree to tree and branch to branch incessantly sometimes close to the ground, sometimes high up. Even when seated, it seems unable to keep its body quiet, but keeps bobbing and bowing. It always keeps its crest fully erected. Its note is a sharp clicking metallic rattle."
