Ryan Photographic - Accipitridae - Hawks,eagles, harriers and old world vultures
The accipitrids are a diverse group, ranging in size from tiny sparrowhawks to the enormous cinerous vulture which is one of the heaviest flying birds. They all possess superb vision which, in some species, may be eight times more acute than in humans. They are found on all continents except Antarctica (an obvious, but familiar theme). While some, such as the Harpy Eagle, are massive, they don't quite approach the size of New Zealand's extinct Haast's eagle, Harpagornis moorei which is believed to have weighed up to 16.5 kgs.
In most accipitrids the females are significantly bigger then the males although this size differential is much less amongst those species which scavenge. Wikipedia provides more information here.
