Urban peregrine falcons have recovered significantly due to nest box programs, but their welfare is increasingly affected by urban light pollution, window strikes, and vehicular collisions with fledglings during first flights.
Urban peregrines face welfare challenges that their wild counterparts do not — glass buildings that are invisible barriers, road traffic during ground-level fledgling recovery, and light pollution that disrupts circadian rhythms. Fledglings learning to fly are particularly vulnerable, with many requiring rescue and rehabilitation after collisions. The welfare infrastructure around urban peregrine populations — nest cams, fledge-watch volunteers, and licensed wildlife rehabilitators — is an important part of making urban nesting viable.
