Peregrine falcons have made a remarkable recovery from near-extinction, but urban nesting populations face welfare challenges including glass strikes, prey contamination, and human disturbance.
The peregrine recovery story is one of conservation success, but urban populations encounter hazards absent in natural habitats. Fledgling falcons learning to fly in glass-dominated urban canyons suffer high collision rates in their first weeks. Anticoagulant rodenticides bioaccumulate through the prey chain, causing internal bleeding in raptors. Monitoring programs that track urban nest success and rehabilitate injured birds are essential components of sustaining recovered populations.
