Glossy IbisPlegadis falcinellus
22-25" (56-64 cm). W. 3'1" (94 cm). A large, all-dark marsh bird with a down-curved bill. Plumage rich chestnut in breeding season; wings glossy greenish; eyes brown. The bare face is outlined by a thin line of white. Breeding White-faced Ibis similar, but has broader band of white feathers around bare face, red eyes, and all-red legs.
