Frequently asked questions
Will a peregrine falcon hurt me?
No. They hunt birds, not people. Maintain 25 yards distance and you're perfectly safe. They actually avoid humans.
Are peregrine falcons rare?
Once endangered from DDT pesticides, they've made a remarkable recovery since the 1970s ban. Now common in suitable habitat with cliff nesting sites.
What do they eat?
They hunt medium-sized birds mid-flight—mostly pigeons and ducks where cities offer prey, and local bird species in wilderness like Great Basin.
Where do they nest?
On cliff edges and tall vertical surfaces. They scrape a shallow depression in the cliff rather than building a traditional nest.
When is the best time to see them?
Dawn during spring and summer (April-August) when breeding activity is highest. They're diurnal but most active at first light.
What makes peregrine falcons special?
They're one of conservation's greatest success stories—nearly extinct from DDT poisoning in the 1970s, they've recovered remarkably through protection efforts. Watching one is witnessing a triumph of environmental law and species recovery.
