* Adults among the Buzzards usually have the tail much less numerously- 

 barred than is the ease with young birds and often have a broad sub-terminal 

 band, lacking in young birds : the latter also have the under -parts of the 

 liody as a rvile lighter, often with the arrow-head, circular or elong.ated dark 

 markings characteristic of the young ])irds of other groups of the Accipitre.<i, 

 Individuals of all the species of Bnteo vary greatly in plumage.
