The White-faced Ibis probes wet mud with its long bill for food. Its plumage can shine green and purple.
Adult plumage shines green, purple and bronze. In breeding plumage, adults have red around the eye and a white border on the face.
It wades through shallow wetlands and probes mud with its long, downcurved bill for insects and other small animals.
The female usually chooses among nest sites offered by the male. Both help gather material and build a platform of reeds or sticks in vegetation or low woody plants over shallow water.
In the North American breeding account, clutches contain 3–5 eggs and incubation lasts 17–21 days. Both parents incubate and feed the chicks.
Nonbreeding adults and immatures lack the white facial border and have more matte brown plumage. Juveniles are paler brown, with pale cheeks and patches of white neck feathers.
