Wild Peregrine Nesting Welfare

Peregrine falcon nesting welfare is influenced by disturbance, prey availability, and urban hazards in both rural and city environments.

Key Facts

Peregrines lay 3 to 4 eggs in spring and both parents incubate for 29 to 32 days
Nest disturbance during incubation causes egg cooling and embryo death
Urban peregrines face prey contamination from second-generation rodenticide-exposed pigeons
A disturbed falcon may not return to incubate, leaving eggs abandoned
UK peregrine populations have recovered from near-extinction following pesticide bans

Welfare Considerations

Peregrine chicks that die from nest disturbance suffer from hypothermia and starvation over days. Adults disturbed from incubation experience the stress of displacement and failed breeding attempts.

What You Can Do

Respect buffer zones around known peregrine nesting sites
Support UK Peregrine Project monitoring and protection programs
Advocate for second-generation rodenticide restrictions to reduce prey contamination
