Diet / Feeding
Ibises mostly feed in shallow waters on aquatic insects, mollusks, frogs, and food sifted from the water surface.
Their diet also includes insects caught on land, as well as lizards, worms, skinks, and other small reptiles.
They typically nest in colonies, with other water birds.
The nests are shallow cup-shaped platforms of sticks, grasses or reeds that are typically situated on trees near a body of water, such as rivers, swamps or lakes. Although some ibises also make their nest amongst rocks and on cliffs,
The average clutch consists of 2 – 4 eggs. The nests are often reused year-after-year.
