Urban peregrine falcons have established significant breeding populations in UK cities, with welfare supported by artificial nest ledges and human tolerance.
Urban peregrines that have adapted to city environments demonstrate how flexibility and human tolerance enables wildlife welfare within human-modified landscapes. The provision of artificial nest ledges on buildings creates nesting opportunities that individual breeding pairs benefit from directly. Illegal persecution of nesting urban peregrines - rarer than in rural areas but still occurring - causes direct welfare costs and population damage.
