Description

The white Ibis is a medium-sized bird with beautiful white plumage that is a known wanderer. It makes a quiet grunting "croo croo" noise as it forages for food. Unfortunately, these birds have been heavily impacted by the pollutant methylmercury. In the Everglades high concentrations of methylmercury from human pollution have greatly impacted the mating behavior and mating frequency of the white Ibis.

Nest Placement
Tree
Feeding Habits
White Ibis engage in tactile foraging in wetlands, employing a probing technique with their bills to locate prey such as insects, crustaceans, fish, frogs, and other small animals. Predominantly they capture crayfish, earthworms, marine worms, and crabs. Once detected, prey is pinched and either consumed immediately or washed. Hard-shelled food is broken before ingestion, and claws are removed from crabs.
Habitat
White Ibis typically inhabit a variety of wetland environments, ranging from swamps, mangroves, flooded pastures, to freshwater marshes, and shallow ponds. They favor ecosystems with sparse, short vegetation and usually less than 8 inches of water. These birds are also found in coastal regions, including brackish and saltwater marshes, as well as in savannas and grasslands adjacent to aquatic habitats. Renowned for their adaptability, white Ibis may also frequent urban areas like park lawns, particularly in southern Florida. Nesting primarily occurs in colonies located in trees and shrubs near water bodies, with a preference for freshwater sources during breeding to accommodate the dietary needs of their young.
Nest Behavior
White Ibis's nest construction lasts about 7 days, with ongoing maintenance. Males supply nesting material, while females mainly assemble the nest. Details on egg-laying and parental care are unspecified.
Nest Characteristics
White Ibis typically nests in forks of trees like elderberry or mangroves, or grass clumps, at 0.5–12 feet high. They form a roughly 10-inch-wide, 2–4-inch-tall platform nest with sticks collected by the male.
Dite type
Aquatic invertebrate eater

Behavior

White Ibis are highly sociable and engage in collective activities from foraging to nesting. They leisurely peruse wetlands for food, displaying a probing and picking technique in their search for sustenance. Marked for their communal flights at noteworthy speeds, they also exhibit an unconventional plunging into roosts that betrays their otherwise elegant demeanor. Integral to their distinctiveness are elaborate courtship displays, encompassing synchronized flights and nuanced preening, aimed to entice mates. Notably, males may engage in polygamy via extra-pair couplings, aggressively defending their chosen mates and offspring. The species demonstrates biparental care in egg incubation and chick nurturing, though juveniles exhibit a lag in mastering foraging the periphery, dependent on parental care for extended periods.

Distribution Area

The American white ibis is most common in Florida, where over 30,000 have been counted in a single breeding colony. It also occurs throughout the Caribbean, on both coasts of Mexico (from Baja California southwards) and Central America, and as far south as Columbia and Venezuela. The non-breeding range extends further inland, reaching north to Virginia, and west to eastern Texas.
