The Corn Crake bird (Crex crex) is also known as the landrail. The Corn Crake bird is a small bird belonging to the family ‘Rallidae’. The adult Corn Crake is 22 – 25 centimetres long and has mainly brown, heavily spotted upperparts, a blue-grey head and neck and reddish streaked flanks.
The Corn Crake bird has a short bill and shows chestnut wings and long dangling legs in flight. Both male and female are similar, however, in the immature bird the blue-grey is replaced by a buff coloring. The downy chicks are black, as with all rail birds.
The Corn Crake birds breeding habitat is not marshes as with most crakes, but, as the name implies, meadows and arable farmland. The Corn Crake bird breeds across Europe and western Asia, migrating to Africa in winter. The Corn Crake is very secretive in the breeding season, and can be heard considerably more than it can be seen. It is hard to flush, walking away through the vegetation.
The Corn Crake birds song, mainly heard at night and very early morning, is a repetitive, far-carrying ‘crex crex’, like two notched sticks being rubbed together. The Corn Crake feeds mainly on insects.
The Corn Crake bird is in deep decline across most of its range because modern farming practices mean that nests and birds are destroyed by mowing or harvesting before breeding is finished.
The best place to look and listen for Corn Crake birds in the UK is in the Outer Hebrides of Scotland.

A Voice More Often Heard Than Seen
The Corn Crake is famously secretive during the breeding season, and the vast majority of people who encounter this bird will do so through sound alone. It is hard to flush, preferring to walk swiftly and silently away through dense vegetation rather than expose itself to open view. Its song, heard most often at night and in the very early hours of the morning, is a repetitive, far-carrying rasping call that gives the species both its common name and its scientific one: crex crex, like two notched sticks being drawn rapidly across one another.
Once heard, it is unmistakable and oddly compelling, a sound that drifts across dark fields with a mechanical persistence that can last for hours. In areas where Corn Crakes are present in good numbers, a chorus of calling males on a warm June night is one of the more extraordinary wildlife experiences the British countryside has to offer.
Feeding and Behaviour
The Corn Crake feeds mainly on insects, though its diet is broader than this suggests and includes earthworms, slugs, snails and a variety of small invertebrates encountered during its patient foraging through tall vegetation. It picks its way through grass and crops with a deliberate, slightly hunched gait, using the cover of dense stems to remain concealed almost continuously.
Outside the breeding season, when it is not announcing its presence vocally, the Corn Crake can spend weeks in an area without being seen by anyone, including people specifically looking for it. This talent for invisibility is one of its most defining characteristics and, under different circumstances, one of its greatest assets.
Breeding and Nesting
The nest is a simple cup of grass and leaves, built on the ground and well concealed within tall vegetation. The female lays between six and fourteen eggs, which are incubated for around 16 to 19 days. Chicks are precocial, meaning they are mobile and capable of following their mother almost immediately after hatching.
The female raises the brood largely alone, though she may begin a second clutch with a different male while the first brood is still young. This capacity for multiple broods in a season is part of what makes the Corn Crake’s current decline so frustrating from a conservation perspective: the potential for population recovery is there, but the conditions needed to realise it have become increasingly difficult to find.
Decline and Modern Farming
The Corn Crake is in deep decline across most of its range, and the cause is not difficult to identify. Modern farming practices, particularly the mechanised mowing of hay meadows and silage fields, have transformed what was once suitable habitat into something far more hazardous. Corn Crakes nest on the ground in tall grass, and the timing of their breeding season overlaps almost perfectly with the cutting of crops.
Mowing machines move from the outside of fields inward, driving birds and chicks toward the centre before the final cuts destroy nests and kill birds that have nowhere left to run. The shift from traditional hay-making, which took place later in summer, to silage production, which begins considerably earlier, has compressed the window available for successful breeding to a point that many populations simply cannot sustain.
Where to Find Corn Crakes in the UK
The best place in the United Kingdom to look and listen for Corn Crakes is the Outer Hebrides of Scotland, where traditional crofting practices have survived longer than in most of lowland Britain and where sympathetic land management has helped maintain a small but meaningful population. The RSPB and other conservation organisations have worked with farmers in these areas to encourage late mowing and the retention of rough field margins, measures that give nesting birds a fighting chance.
Standing in a Hebridean meadow at midnight, listening to that extraordinary rasping call carry across the darkness, it is impossible not to feel both the privilege of the moment and the quiet urgency of ensuring it remains possible for generations to come.
