Marabou storks Leptoptilos crumeniferus obtained as yearlings in 1979 and kept in a mixed-species aviary at Jacksonville Zoo, first displayed courtship and nesting behaviour in 1985 but the eggs were infertile. Three eggs removed for artificial incubation in 1987 produced one chick; it was hand-reared but did not survive to maturity. Between 1990 and 1993 six chicks were hatched and successfully reared by the parents. The paper reports hand-rearing diet and behavioural observations of the breeding birds and notes participation of juvenile in rearing the following year's chick.
