Threskiornithidae is a family of wading birds that includes ibises and spoonbills. They are recognized by their long, decurved bills (ibises) or flattened, spoon-shaped bills (spoonbills), which they use to probe for food in shallow water. These birds are often found in wetlands, marshes, and near shorelines. They are social, often nesting in colonies, and their diet consists primarily of fish, crustaceans, and insects.
