- All year on the cliffs and short grass around the Marloes peninsula and Skomer. Breeding pairs build nests in early spring and raise chicks in caves from May–July.
- Where in the game
- the Pembrokeshire coast (clifftop, sea cliff, cove and island)
- Size
- 39–40 cm
- Wingspan
- 73–90 cm
- Weight
- About 330 g
- Lifespan
- Typically 7 years once breeding; oldest ringed bird 23 years (BTO)
- Population
- 335 pairs in the UK in 2014–15 (BTO); a 2014 survey found 433 pairs in the UK and Isle of Man, 236 of them in Wales. Skomer had seven territories in 2024 (Wildlife Trust of South & West Wales)
- Status
- Green list, UK Birds of Conservation Concern, despite the small population (BTO)
Diet
Soil, ground and dung-dwelling invertebrates, probed out of short grazed turf with the curved bill
Habitat
Sea cliffs and coastal grassland, heath and dunes on the far west coast
Breeding
Nests in coastal caves above the high-tide line and in crevices. Clutch 3–5 eggs; incubation 17–18 days; chicks fledge after 31–41 days; one brood
Field signs
- Glossy black crow with a long, curved red bill and red legs
- Playful, tumbling, diving flight on windy days along the cliff edge
- A ringing, high 'chee-ow' call, different from a jackdaw's 'jack'
- Birds probing the short turf, or flocks roosting on the cliffs in autumn
Did you know?
- Skomer's choughs held seven territories in 2024, and the autumn roost count around south Pembrokeshire reached 59 birds.
- The UK chough population was 433 pairs (including the Isle of Man) in 2014, up 34% since 1992 (BTO).
- Wales holds more than half of the UK's breeding choughs: 236 of the 433 pairs in the 2014 survey (BTO).
Moments worth waiting for
- Cliff-edge aerobatics
Two choughs tumble and dive along the cliff edge on the wind, calling as they twist together.
Photo tip
Choughs are wary, so use a long lens from a fixed spot and let them work the turf near you: a windswept clifftop with grazing ponies or sheep is good. Slightly underexpose to keep the gloss on the black feathers; in flight use 1/2000 s.
Be a good naturalist
Chough is on Schedule 1, so disturbing nests or chicks is a criminal offence: keep well away from cliffs and caves where a pair may be nesting, never use playback, and leave any nest site alone.
The law
Schedule 1 of the Wildlife and Countryside Act 1981: it is an offence to disturb a nesting bird or its young without a licence
