Content Image

This is the most widespread ibis species, breeding in scattered sites in warm regions of Europe, Asia, Africa, Australia, and the Atlantic and Caribbean region of the Americas.Glossy Ibis feed in very shallow water and nest in freshwater or brackish wetlands with tall dense stands of emergent vegetation such as reeds,papyrus or rushes) and low trees or bushes. They show a preference for marshes at the margins of lakes and rivers but can also be found at lagoons, flood-plains, wet meadows, swamps, reservoirs, sewage ponds, paddies and irrigated farmland. It is less commonly found in coastal locations such as estuaries, deltas, salt marshes and coastal lagoons. Preferred roosting sites are normally in large trees which may distant from the feeding areas.

The nests are usually a platform of twigs and vegetation positioned at least 1m above water, sometimes up to 7 m in tall, dense stands of emergent vegetation, low trees or bushes.

The diet of the Glossy Ibis is variable according to the seaonand is very dependant on what is available. Prey includes adult and larval insects such as aquatic beetles, dragonflies, damselflies, grasshoppers, crickets, flies and caddisflies, Annelida including leeches, molluscs (e.g. snails and mussels), crustaceans (e.g. crabs and crayfish) and occasionally fish, amphibians, lizards, small snakes and nestling birds.

This species is 55–65 centimetres (22–26 in) long with an 88–105 centimetres (35–41 in) wingspan. Breeding adults have reddish-brown bodies and shiny bottle-green wings. Non-breeders and juveniles have duller bodies. This species has a brownish bill, dark facial skin bordered above and below in blue-gray (non-breeding) to cobalt blue (breeding), and red-brown legs. Unlike herons, ibises fly with necks outstretched, their flight being graceful and often in V-formation.

Sounds made by this rather quiet ibis include a variety of croaks and grunts, including a hoarse grrrr made when breeding.

In the Danube Delta is a comun bird, easy to see near the canals and lakes.
