Marsh Harrier Wetland Welfare and UK Recovery

Marsh harriers were reduced to a single breeding pair in the UK by 1971 due to persecution and wetland drainage. Their recovery to over 400 breeding females is one of British conservations greatest successes.

Key Facts

Marsh harriers nest in extensive reedbeds and hunt over open water and wetland margins
Females do most of the incubation while males provide food
They were heavily persecuted as perceived threats to gamebirds
Climate change is allowing range expansion northwards in Europe

Welfare Considerations

Marsh harriers still face illegal persecution on some estates, including shooting and poisoning. Nestlings in extensive reedbeds are vulnerable to flooding during high spring water events that have become more frequent with climate change. Competition for reedbed territory is intense as populations grow and suitable habitat remains limited. Disturbance by birdwatchers with long-lens cameras at established nest sites can cause nest abandonment if birds are approached too closely.
