Peregrines have successfully colonised cities across Britain, nesting on cathedrals and tall buildings, with welfare challenges from human disturbance and urban-specific hazards.
Urban peregrines face welfare challenges specific to city environments including window collisions by fledgling birds, disturbance at nest sites by humans seeking views or photographs, and exposure to rodenticide-poisoned prey. The abundance of urban pigeons provides excellent foraging but birds that have fed on rat-poisoned pigeons accumulate rodenticide loads. Fledgling peregrines in their first flights navigate glass-fronted buildings and busy roads before developing the aerial precision of adults, creating a vulnerable window of elevated mortality risk.
