Dotterel Welfare: Arctic-Alpine Breeding in Scotland

Dotterels breed on high arctic-alpine plateaux in Scotland in small numbers, with welfare challenges from disturbance by hill walkers and climate-driven habitat change at high altitude.

Key Facts

Scotland's dotterel breeding population is estimated at 500-900 pairs on high mountain plateaux
Dotterels show sex-role reversal, with males incubating eggs and caring for chicks while females may mate with multiple males
Their mountain plateau breeding habitat is at risk of being lost as vegetation zones shift upslope with climate change
Hill walkers inadvertently disturbing incubating dotterels are a welfare concern on popular Munros

Welfare Considerations

Dotterel welfare is concentrated in the short, intense breeding season on exposed mountain plateaux. Incubating males sitting on cold, exposed ground are highly cryptic and easily flushed by walkers — repeated disturbance causes nest failure through egg chilling. Climate-driven upslope vegetation shifts compress available bare-ground plateau habitat, intensifying competition. In poor weather years, invertebrate availability for chicks is reduced, causing nutritional stress. Responsible access guidelines for popular mountain areas during the May-June breeding season significantly reduce welfare impacts from hill walkers.

What You Can Do

Follow responsible access guidance on popular Munros and plateaux during May-June dotterel breeding season
Stay on paths and avoid lingering on high plateau areas if you see cryptic ground-nesting birds
Support high-altitude bird monitoring that tracks dotterel population trends and habitat use
