tent. Finally they settle down, each crowding close to its mate. I have 

 often seen them in moonlight nights remain quietly asleep for several 

 hours, and then as if by a common impulse leave the tree with a loud 

 whirring of wings, but otherwise in utter silence, to seek another tree. 

 I was unable to discover the cause of these strange maneuvers. Iris 

 orange. 



Five specimens.

 None secured. 



60. Rupornis ruficauda (Scl. & Salv.). 



Abundant. The commonest Hawk of the region. Seems to prefer 

 rather open woods, although often seen in the thickest forests. Iris 

 yellow. Cere'orange-yellow. 



Five specimens secured. 



61. Asturina plagiata (Schleg.). 



This bird is apparently not common in that region. While out hunt- 

 ing one day I shot at one of these Hawks, but it flew away apparently 

 unhurt. Three days afterward, while in a different direction, I found 

 this same bird dead in a hollow tree, where it had evidently just died of 

 starvation on account of a single shot in the last joint of the wing. Iris 

 brown. Cere and feet yellow.
