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

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

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

 body as a rule lighter, often with the arrow-head, circular or elongated dark 

 markings characteristic of the young birds of other groups of the Accipitres, 

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