Red-naped Ibis or Indian Black Ibis, Pseudibis papillosa

Pseudibis is an Asian genus of Ibises (wading birds) that occurs naturally in open, grassy habitats.

Ibises resemble herons and share many of their habitats and behavioral traits, but unlike herons, ibises fly with necks outstretched and often in V-formation.

Subspecies and Ranges

  • The critically Giant Ibis – from northern Cambodia is also sometimes placed in this genus.

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.


Most breeding activities are observed after the rainy season, when plenty of food is available.

They typically nest in colonies, often 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.
