The White-faced Ibis is
the Ibis most commonly found in South Dakota. It is very similar to the
Glossy Ibis, but the two species ranges are generally
distinctive. Where they do overlap, intermediates (possibly
hybrids) can make positive identification nearly impossible. They
currently appear to be expanding in both range and in number.
Habitat: Prefers shallow freshwater marshes,
flooded fields, rice paddies. Will also forage in saltwater marshes.
Diet: Mostly insect and crustaceans,
also earthworms, frogs, tadpoles, snails, leeches, and small fish.
Behavior: Forages in shallow water, probing for
food items in the muddy bottom. They will also take insects and other prey
from the water's surface, or by foraging on dry land.
Nesting: June and July
Migration: Summers in scattered locations throughout the central and western United
States. Winters in California, Arizona, the Gulf Coast, and points south.
Similar Species: Glossy
Ibis. Juvenile White
Ibis can appear similar.
Conservation Status: Has increased in number since the 1970s,
and is expanding in range. Previous declines are attributed to DDT and
