Peregrine Falcon Welfare: Conservation and Urban Ecology

Key Welfare Considerations

• Peregrine populations crashed in the 1950s-70s due to DDT and dieldrin causing eggshell thinning and reproductive failure.
• Post-ban recovery represents one of wildlife conservation's greatest success stories, with UK populations exceeding 1,800 pairs.
• Urban peregrines face novel welfare challenges including glass collisions, light pollution, and rodenticide exposure.
• Secondary rodenticide poisoning from rat control programmes poses a significant welfare risk to urban peregrines.
• Peregrines are apex predators — welfare monitoring provides valuable data on wider food web health.
• Nest ledge availability on tall buildings, bridges, and cliff faces limits urban breeding success.
• Artificial nest boxes on high buildings have significantly increased urban breeding opportunities.
• Chick mortality from nest ledge falls is a significant welfare concern at urban nest sites.
• Peregrine welfare monitoring programmes involving nest cameras have increased conservation engagement.
• Illegal persecution including egg collection and shooting remains a welfare and legal concern.
• Falconry-origin releases of peregrines must be managed to avoid genetic pollution of wild populations.
• Lead poisoning from ingesting shot prey remains a chronic welfare problem for peregrines.
• Climate change affects prey availability timing, creating welfare mismatches during breeding seasons.
• Ringing and satellite tracking programmes provide welfare and behavioural data to guide conservation.
• Peregrines serve as ecological indicators — protecting their welfare supports broader ecosystem health.
