White Ibis Description

They are long-legged wading birds with white wings. Their large curved beak helps them eat. Females have shorter bills and wingspans than males. Adolescent white ibises have no feathers for 4–5 days. The feathers are dark gray and will not become white until adulthood. Juvenile white ibises have a pinkish-white, straight beak. Soon after the first two weeks, the bill begins to lengthen, bend downward, and resemble an adult bill. A white ibis’ sexually monomorphic alterations occur during the breeding season.

Feeding

White ibises may relocate owing to changes in water depth, which affects their eating and breeding habits.

Habitat

White ibises are colonists. These birds live in huge colonies of 500 to 15,000 birds. Large colonies help protect them from predators. If a predator threatens the colony, large numbers of ibises will gather together to help. The colony feeds, forages, nests, mats, and roosts together.
