Crikey, what an absolute champion! This crow-sized raptor is one of the world's most widespread hunters, zipping through the sky with incredible speed to snatch birds mid-flight. Watch these mates-for-life nest on Great Basin's cliff faces—and witness a genuine conservation triumph after nearly vanishing from DDT poisoning.
📏 Keep your distance: 25 yards minimum—maintain distance to avoid startling or stressing the bird.
Stay safe
Maintain 25-yard minimum distance. Never approach active nest sites on cliff edges. Use binoculars for safe observation. Do not disturb nesting birds during breeding season.
If you encounter one
Do not approach. If near a nest site, back away slowly and quietly. Use binoculars to observe safely from 25+ yards away. Report disturbances to park rangers.
Never feed or approach wildlife — it's dangerous for you and often fatal for them.

- Crow-sized. Females considerably larger than males (exact weight not documented for Great Basin population).
- Identifying features
- Crow-sized with slate-blue back and barred white underparts. Distinctive black head marking. Females noticeably larger than males. Unmistakable in flight with pointed wings and sleek profile.
- Habitat
- Cliff edges and canyon walls at high elevations. Needs tall vertical nesting substrate.
- Diet

- Active
- Diurnal (active during daylight; most visible at dawn and dusk)
👀 Where & when to see them in Great Basin National Park
Where to look
Cliff faces and canyon walls at high elevations. Exact viewing hotspots unknown.
Best time
Early morning (dawn) when activity peaks. Active during daylight hours.
Spotting tips
- Spot the distinctive dark silhouette and pointed-wing profile
- Watch cliff faces during early morning hours
- Scan from overlooks and high viewpoints
- Listen for their distinctive cries
- Look for swift aerial hunts or dives
With kids
Excellent for family viewing with binoculars from safe distance. Teach children to observe from afar and never approach nest sites. Binoculars make this a rewarding experience for all ages.
📷 Photographing them
Best vantage points
Cliff overlooks and high-elevation viewpoints throughout the park. Wheeler Peak Scenic Drive area. Exact hotspots unknown—consult park rangers.
Bring
Binoculars essential for safe viewing. Telephoto lens (400mm+) recommended for photography. Notepad for sighting records.
Shoot ethically
Maintain 25-yard minimum distance. Never disturb nesting sites. No baiting or call playback to lure birds. Observe and photograph from established viewpoints only.
🔭 Gear that helps you spot them
🌲 Natural history
- Breeding season
- Spring and early summer (typical April-August for northern populations). Exact dates for Great Basin unknown.
- Migration
- Many northern populations migratory; migration status for Great Basin population unknown.
- Winter
- Does not hibernate—remains active year-round, though some populations migrate seasonally.
🌍 Conservation
Threats
Historical pesticide contamination (now banned). Ongoing need to protect cliff nesting habitat from disturbance.
Protection efforts
Protected under federal Migratory Bird Treaty Act. Nesting sites are monitored and protected from human disturbance during breeding season.
How visitors help
Respect closed nesting areas during breeding season. Report all sightings to park staff to support citizen science. Stay on designated trails to minimize disturbance.
Report sightings
Report sightings to park rangers at Great Basin Visitor Center or contact park headquarters via NPS website.
❓ Questions people ask
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.
