Eurasian Spoonbill – Platalea leucorodia

is a wading bird of the ibis and spoonbill family This is a Palearctic species, breeding from the United Kingdom and Spain in the west through to Japan, and also in North Africa. In Europe, only the Netherlands, Spain, Austria, Hungary and Greece have sizeable populations. Most birds migrate to the tropics in winter, with European breeders mainly going to Africa, but a few remaining in mild winter areas of western Europe south to the United Kingdom. It was extirpated from the United Kingdom but sporadic breeding attempts in the early 21st century culminated with the formation of a colony at Holkham in Norfolk in 2010. In 2011, 8 breeding pairs nested, successfully fledging 14 young. This species is almost unmistakable in most of its range. The breeding bird is all white except for its dark legs, black bill with a yellow tip, and a yellow breast patch like a pelican. It has a crest in the breeding season. Non-breeders lack the crest and breast patch, and immature birds have a pale bill and black tips to the primary flight feathers. Unlike herons, spoonbills fly with their necks outstretched. The Eurasian spoonbill differs from the African spoonbill with which in overlaps in winter, in that the latter species has a red face and legs, and no crest.

They are mostly silent. Even at their breeding colonies the main sounds are bill snapping, occasional deep grunting and occasional trumpeting noises.
