Male and female corncrakes are very similar in appearance; both have light yellowish-brown plumage, and the face and upper parts of the breast are pale grey. In flight their long dangling legs, chestnut wings and buff coloured underparts are visible. The corncrake is easier to hear than to see, the call is a repeated rasping 'crrek crrek' similar to a nail scraping along a comb (2). The scientific name of this species, crex crex refers to this call (4).
