t 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, and have only 
first 3 primaries notched in some cases. 
vary greatly in plumage.
