Abstract
White ibises (Eudocimus albus) are members of the family Threskiornithidae in the order Ciconiiformes. They are medium-sized wading birds with a tapering decurved bill. Adults are white with black tips on the four largest primaries. Males tend to be 35% larger than females, averaging 1,036 ± 30 g (33 ± 1 oz) (Kush1an 1977c). White ibises inhabit open marshes and other wetlands where they are one of the most important predators in the food chain in terms of energy flow (Kush1an 1977b; Rodgers and Nesbitt 1979). In the past, white ibises have been occasionally harvested by humans for food (Baynard 1913; Bent 1926).
