Calidris tenuirostris (Great Knot)

Synonyms: Totanus tenuirostris (homotypic)

Wikipedia Abstract

The great knot (Calidris tenuirostris) is a small wader. It is the largest of the calidrid species. The genus name is from Ancient Greek kalidris or skalidris, a term used by Aristotle for some grey-coloured waterside birds. The specific tenuirostris is from Latin tenuis "slender" and rostrum "bill". Their breeding habitat is tundra in northeast Siberia. They nest on the ground laying about four eggs in a ground scrape. They are strongly migratory wintering on coasts in southern Asia through to Australia. This species forms enormous flocks in winter. It is a rare vagrant to western Europe.
