South A\'ales. I never observed it to attack the fowls ; and I 

 have some recollection of the natives telling me its principal 

 food was field-mice. I have seen it at times hover in the air 

 apparently motionless and stationary. It is a migratory species. 

 I have noticed one as early in the season as February 9th, 1805.

The Elanus melanopterus appears to be spread over a vast 

 extent of the Old World, being numerous in Egypt, and the 

 oreater part of Africa, as far as to the Cape of Good Hope. It has 

 also been met with in various parts of India, in Java, and New 

 Holland. There seems to be a considerable variation in the 

 pluma o-e of this species, the black markings of the wing spread- 

 ing to a greater or less extent in difterent specimens.
