There is very little information about the breeding biology of Greater Yellow-headed Vulture. Copulation has been observed in French Guiana in August (Tostain et al. 1992). Without providing any details about location or sample size, Ferguson-Lees and Christie (2001) describe the nest as in a large tree cavity, the clutch as two, and the eggs as white (perhaps this account is based on Penard and Penard 1908?). There is no information on the length of incubation or the nestling period. and a single nest site has been reported from a tree cavity (Ferguson-Lees and Christie, 2001). Cathartid vultures generally reach maturity after about three years, and usually lay eggs on the ground in caves or under dense bushes, in hollow logs or tree stumps, or in large cavities in trees (Houston 1994b).
