What is the fastest bird?
Common swift fastest in level flight; peregrine falcon fastest in hunting dive — over 320 km/h stoop.
In brief
In level flight, the common swift (Apus apus) holds the record at roughly 111 km/h (69 mph). In a hunting stoop (dive), the peregrine falcon exceeds 320 km/h (200 mph) — the fastest verified animal movement.

Bird speed depends on measurement: level flapping flight, gliding or gravity-assisted dive. Common swift (Apus apus) holds level flight record at roughly 111 km/h. Peregrine falcon exceeds 320 km/h in hunting stoop — fastest verified animal movement. Swifts spend months airborne feeding on insects. Wind turbines and glass collisions kill millions of birds annually — separate from speed records but central to conservation.

Quick facts
| Level flight | Common swift ~111 km/h (69 mph) |
|---|---|
| Dive speed | Peregrine falcon 320+ km/h stoop on prey |
| Measurement | Speed varies by method — flap, glide or dive |
| Swift lifestyle | Highly aerial — minimal time on ground |
| Peregrine recovery | Urban nesters recovered after pesticide bans |
| Modern threats | Glass, turbines, habitat loss — not speed-related |
Key takeaways
- Level flight record: common swift ~111 km/h.
- Fastest dive: peregrine falcon 320+ km/h.
- Specify measurement type when comparing speed.
- Swifts live highly aerial lives.
- Peregrines recovered after DDT ban in many cities.
- Glass and turbines kill millions of birds yearly.
Level flight champions
Common swifts feed, mate and sleep on the wing — landing mainly to nest. Streamlined body and long wings suit sustained high-speed flight chasing insect swarms. Alpine swift and white-throated needletail also rank among fastest level fliers. Records come from tracking and radar — not easy to measure in field. Speed serves catching aerial prey and migrating long distances — swifts winter in Africa, breed in Europe, crossing Sahara without stopping style of other species.
Peregrine stoop
Peregrine falcons strike prey in steep dive — wings partially folded reducing drag. Impact often kills prey instantly. Adaptations include bony nasal tubercles slowing airflow to lungs and nictitating membrane protecting eyes. Urban peregrines nest on skyscrapers preying on pigeons — recovery story after DDT pesticide crash mid-twentieth century. Falconers knew speed centuries before radar confirmation — biology now documents physics of stoop exceeding 320 km/h in trained birds with loggers.
Other speed contexts
Golden eagles and gyrfalcons also dive fast but peregrine holds verified maximum. Ostriches run fastest on land among birds — over 70 km/h — different category from flight. Hummingbirds beat wings fastest — metabolic power, not horizontal speed. Comparing records requires specifying measurement type — AI Overviews often conflate categories; WARN separates level flight and stoop for accuracy.
Conservation beyond records
Fast birds still die on glass facades and wind turbines — peregrines less affected than migratory songbirds but not immune. Swift nest site loss in eaves of renovated buildings reduces breeding habitat. Speed evolution irrelevant if migration stopover wetlands drained — see bird migration answer. RSPB and American Bird Conservancy document collision mitigation — patterned glass, turbine curtailment during peak migration.
