Range and Habitat
White-faced Ibis: Breeds from Oregon sporadically east to Minnesota and south to southeastern New Mexico and Texas, and east to coastal Louisiana. Spends winters from southern California and the Gulf Coast of Texas and Louisiana to El Salvador. Preferred habitats include salt and fresh marshes in the west, and coastal marshes and brushy islands in Louisiana and Texas.
Breeding and Nesting
White-faced Ibis: Two to five pale blue green to dark turquoise eggs are laid in a shallow cup of reeds lined with grass and built in a low marsh bush. Incubation ranges from 17 to 26 days and is carried out by both parents.
Foraging and Feeding
White-faced Ibis: Their diet includes crayfish and other invertebrates and frogs and fish. Coastal birds forage in salt marshes and include crabs in their diet. Their legs and neck are long, and they have a long decurved bill which facilitates foraging in shallow water or probing mud. They frequent shallowly flooded pond margins, reservoirs and marshes. They feed in large flocks of up to 1,000.
Vocalization
White-faced Ibis: While feeding, emits a multi-syllable "oink." Also makes a low-pitched "graa-graa-graa."
