The Glossy Ibis, Plegadis falcinellus, is a wading bird of the family Threskiornithidae, known for its striking, sickle-shaped bill. This mid-sized ibis measures 48–66 cm in length, with a wingspan of 80–105 cm. Breeding adults boast reddish-brown bodies and iridescent bottle-green wings, while non-breeders and juveniles display a more subdued coloration. The species is characterized by a brownish bill, dark facial skin with blue-gray to cobalt blue borders, and red-brown legs. In flight, the ibis extends its neck and exhibits a graceful V formation.
When identifying the Glossy Ibis, look for its unique glossy feathers and the distinct shape of its bill. The bird's flight pattern is also a telltale sign, as it flies with its neck outstretched, unlike herons. Listen for its various croaks and grunts, particularly the hoarse grrrr sound during the breeding season.
The Glossy Ibis favors freshwater or brackish wetlands with tall, dense emergent vegetation such as reeds, papyrus, or rushes, and low trees or bushes. It can also be found in lagoons, floodplains, wet meadows, swamps, reservoirs, sewage ponds, rice paddies, and irrigated farmland. Coastal habitats like estuaries and salt marshes are less common for this species.
It is the only ibis which is native to Europe. In Spain, a stable reproductive population has settled in the Guadalquivir marshes.They are easily recognised because they usually fly in a V formation as a group.
This bird usually measures between 55 and 65 centimetres.
The eggs that the glossy ibis lays are greenish blue.
It has a long, curved bill. Adults mostly dark with iridescent green and reddish tones. Very thin white border surrounding the dark facial skin. Dark eyes. Usually gregarious, it is found mainly in salty marshes and shallow wetlands. Unmistakable in most of its range, though American birds are best distinguished from White-faced Ibis by distribution and facial pattern.
