The population of the endangered species has increased due to biodiversity supporting measures by the NTS.

The population of the corncrake, one of Scotland’s rarest birds, has seen a “promising” increase on the isle of Canna, the National Trust for Scotland says.

A survey on the small island in the Inner Hebrides found 12 to 14 calling mates compared to one or two in previous seasons.

Corncrakes have been in decline due to intensive agricultural methods and are one of 26 priority species listed by the trust.

The National Trust for Scotland (NTS) said the “buoyant” population can be attributed to new farming practices that support conservation.
