Behaviour

Chough flock feeding on strandline at the RSPB Oronsay nature reserve
Choughs are sociable birds. Nesting pairs will join daytime feeding flocks to forage outside their immediate territory.

Choughs are sociable birds that are found throughout the year in flocks of up to 30-40 birds.

Pair bond is monogamous and of long duration. Pair-members remain together all year, and tend to join and leave flocks in pairs.

They roost communally outside breeding season, and non-breeders often do so all year. During the breeding season nesting pairs roost at or close to their nest site, and fledged young will return to the nest to roost for about two months after fledging. Nesting pairs will join daytime feeding flocks to forage outside their immediate territory.
