SOME of Scotland’s most endangered bird species are thriving on grouse moors, according to a new survey by one estate.

The survey of endangered nesting birds on an estate in the Grampian mountains has shown an increase in both the number of nesting birds and in the number of different species recorded.

Gamekeepers on Invercauld Estate continued their conservation efforts during lockdown and undertook the survey over three months in the late spring and early summer of red and amber listed species.

These are species listed on the list of Birds of Conservation Concern produced by the Royal Society for the Protection of Birds, British Trust for Ornithology and others which are considered to be the most endangered in the UK.

In total, 1117 breeding pairs of these endangered birds were identified through the survey, an increase of 16% from 2019.
