These birds are only found in the warm parts of 

 South America. They are generally seen in forests 

 on trees^ near the tops of which they reside during 

 the heat of the day^ but in the cool of the morning 

 and evening they are busily engaged in searching 

 for fruits and insects. Their flight is heavy, and 

 performed with difficulty, owing to the shortness of 

 their wings. They build their nests on the summits 

 of trees : the female lays from two to five eggs.
