Wild Marsh Harrier Nest Success

Marsh harrier nest success depends on reedbed quality, prey availability, and freedom from disturbance during incubation.

Key Facts

Marsh harriers build platform nests in dense reedbed
Nest flooding during incubation can destroy entire clutches
Prey including water voles must be accessible nearby
Disturbance during incubation causes desertion and egg chilling
Nesting marsh harriers have recovered to over 500 UK pairs

Welfare Considerations

Marsh harrier eggs and chicks lost to flooding or disturbance represent preventable welfare harm. Reserve managers maintain water levels and manage access to protect nesting marsh harriers.
