Wild Osprey Nesting Success and Climate

Osprey populations have recovered strongly in the UK since recolonisation in the 1950s. Climate change and water quality now interact with nesting success in complex ways.

Key Facts

Ospreys were extinct in the UK for much of the 20th century, returning naturally from Scandinavia
UK breeding population now numbers over 300 pairs and is continuing to expand south
Nest cameras at Loch Garten and elsewhere have created a large public following
Fish availability in rivers and reservoirs is the primary determinant of osprey breeding success
Warm, dry springs can reduce fish surface activity and reduce chick survival

Welfare Considerations

Osprey welfare at nesting sites depends on fish availability, nest integrity and human disturbance levels. Conservation management that protects nesting pairs from disturbance has enabled this remarkable recovery.

What You Can Do

Support the RSPB Osprey Monitoring Programme and nest camera projects
Advocate for clean, fish-rich rivers as essential osprey habitat
Report any disturbance of known osprey nest sites to local wildlife officers
