Plegadis Falcinellus is the only species in Europe with greenish-black plumage, long black legs and long curved bill. The size is bigger than 50 cm. Characteristic wetland species, breeding colonies are usually mixed with other herons. Birds may feed tens of kilometres from the breeding colonies. The Glossy Ibis feeds mainly on aquatic animals.

Glossy Ibisis a patchily distributed summer visitor to southern and southeastern Europe, which accounts for a tiny proportion of its global breeding range. Its European breeding population is relatively small (22,000 pairs), and underwent a moderate decline between 1970-1990. Although key populations in Russia and Azerbaijan were stable during 1990-2000, the species continued to decline in parts of south-eastern Europe, and underwent a moderate decline (10%) overall. Consequently, it is provisionally evaluated as Declining. Glossy Ibis has a nearly cosmopolitan but very fragmented distribution. In Europe it breeds in the Mediterranean regions, the Balkan Peninsula and the eastern parts of the continent. The population of the European Union comprises 52-89 breeding pairs, which represents only 0.5% of the total European population. Being fairly unpredictable in the occupation of its breeding sites, its trends are often difficult to assess, but globally it has undergone a strong decline since the latter part of last century, and its breeding area have definitely contracted. This trend seems even to have been accelerated during the last few decades. The main reasons for this are wetland reclamation, hunting and disturbance of breeding colonies

Characteristic wetland species, breeding colonies are usually mixed with other herons. Lakes, swamps, lagoons, sewage ponds, rivers wet meadows and irrigated cultivation. Roosting sites in large trees often far from water. Nests in freshwater or brackish wetlands, usually in tall dense trees or in low trees or bushes over or near water.

Breeds may in Black Sea area, March-May in North America, during rains or just after in most of Africa. In trees or bushes growing in water, at heights to 5-7 m, or in dense reeds or rushes. Colonial; from a few to thousands of pairs, usually with other Ciconiiformes, also with Pygmy Cormorant. Nest is compact platform of twigs or reeds lined with leaves. 3-4 eggs, incubation 20-23 days. chicks have sooty black down.
