When approaching to capture insects or small birds, which 

 form its prey, it becomes keen and excited, but at other times 

 it appears to be dull and listless. They roam about in flocks 

 of about half a dozen individuals, on the large branches of the 

 great forest trees. They are noisy animals, and in the early 

 morning they make the forest resound with their yelping cries.
