Summary. The literature on the food of Gypohierax is reviewed. First-hand evidence of the bird's catching live fish in the Gambia is cited. Up-to-date information is given about the ecology of the bird in East Africa, with particular reference to its occurrence in the absence of oil-palms and its eating Raffia fruit. On the basis of this and of the survival of Gypohierax in zoos, it is concluded that the vitamin-rich oil-palm fruit is not essential to the bird; but one that had been in captivity for 11 years, when presented with the fruit, preferred that to its usual meat.
