The corn crake (Crex crex) is a bird in the rail family. It breeds in Europe and Asia, and migrates to Africa for the northern hemisphere's winter. It is a medium-sized crake with buff- or grey-streaked brownish-black upperparts, chestnut markings on the wings, and blue-grey underparts with rust-coloured and white bars on the flanks and undertail. The male's call is a loud krek krek, from which the scientific name is derived. The breeding habitat is grassland, particularly hayfields; the female builds a nest of grass leaves in a hollow in the ground and lays 6–14 cream-coloured eggs that hatch in 19 or 20 days. The bird is in steep decline across much of its former breeding range because modern farming practices often destroy nests before breeding is finished. It is omnivorous but mainly feeds on invertebrates, the occasional small frog or mammal, and some seeds. Natural threats include feral and introduced mammals, large birds, and various parasites and diseases. Although numbers have declined steeply in western Europe, the bird is classed as a species of least concern because of its huge range and large populations in Russia, Kazakhstan and western China.
