UK Peregrine Falcon: Recovery and Threats

The peregrine falcon has recovered dramatically since the organo-chlorine pesticide crisis, but faces ongoing threats from persecution and disturbance.

Key Facts

UK peregrine population declined to around 360 pairs in the 1960s due to organochlorine pesticide effects on eggshell thickness
Populations have recovered to over 1,500 pairs by the mid-2020s following pesticide bans
Illegal nest disturbance and egg and chick theft remain significant threats during breeding season
Urban peregrines nesting on buildings have become an iconic urban wildlife conservation story

Welfare Considerations

Individual peregrine welfare is affected by disturbance at nest sites, illegal persecution, and secondary poisoning from rodenticides and lead ammunition. Conservation success depends on effective legal protection and enforcement, particularly during the vulnerable nesting period.

What You Can Do

Avoid approaching known peregrine nest sites during the breeding season March-July
Report suspected nest disturbance or persecution to the RSPB and police
Support raptor monitoring schemes that track peregrine population trends
