Ynghylch

Once widespread, corncrakes have declined dramatically in the UK, and the breeding population is now restricted to a few key areas. Unusually for a rail, they aren't found exclusively in wetlands, preferring to nest in meadows and hay fields. Corncrakes prefer areas with lots of tall plant cover, where they spend most of their time hidden from view - often the only sign a corncrake is present is the strange call given from dusk till dawn. They are summer visitors, wintering in central and southern Africa.

Sut i'w hadnabod

Corncrakes are round-bodied and long-necked, like a water rail, but with a short, stubby bill. The plumage is mostly yellowish-brown, with darker streaks on the back and pale bars on the flanks. There are grey patches on the throat and above the eye.

Dosbarthiad

Breeding corncrakes are now mostly restricted to the western and northern islands of Scotland.

Habitats

Roeddech chi yn gwybod?

Female corncrakes look after the eggs and chicks alone. Although they cannot fly until they're around 35 days old, the female will often abandon her first brood to fend for themseleves at 12 days old, so she can start another nest.
