Observations on the Behaviour of the Scarlet Ibis, Eudocimus Ruber, in Artis Zoo, Amsterdam

Abstract

The Scarlet Ibis, Eudocimus ruber (Linnaeus), fam. Threskiornithidae, is the closest relative of the White Ibis, Eudocimus albus (Linnaeus). The two species live in adjoining geographical areas. Nothing is known about the Scarlet Ibis’s breeding biology in the wild and only little about its breeding biology in captivity. A better understanding of the breeding of this species in captivity should help to improve its management and also to elucidate its relationship with its much better known counterpart, the White Ibis.
