In brief

The peregrine falcon (Falco peregrinus) is a crow-sized bird of prey found on every continent except Antarctica, making it one of the most widespread birds in the world. It hunts other birds in mid-air and is the fastest animal on the planet, reaching over 380 km/h (240 mph) in a hunting dive.

The peregrine falcon (Falco peregrinus) is a crow-sized bird of prey found on every continent except Antarctica, making it one of the most widespread birds in the world. It hunts other birds in mid-air and is the fastest animal on the planet, reaching over 380 km/h (240 mph) in a hunting dive. Adults weigh around 0.9 kg and live up to 15 years in the wild. The species is listed as Least Concern by the IUCN.

Key Facts: Peregrine Falcon

  • No creature moves faster than a peregrine falcon in its hunting dive, known as a stoop.
  • Peregrines are specialist bird-hunters, taking pigeons, ducks, starlings, and shorebirds almost exclusively on the wing.
  • The peregrine is one of the most widely distributed birds on Earth, breeding on every continent except Antarctica and on many oceanic islands.

The fastest animal alive

No creature moves faster than a peregrine falcon in its hunting dive, known as a stoop. Folding its wings tight against its body, the bird drops from height and can exceed 380 km/h (240 mph), far outpacing any cheetah or racing car. Special baffles in its nostrils are thought to keep the rushing air from damaging its lungs, and a third eyelid clears debris from its eyes mid-plunge. In level flapping flight it is far slower, so the record speed belongs entirely to the vertical dive.


Hunting and diet

Peregrines are specialist bird-hunters, taking pigeons, ducks, starlings, and shorebirds almost exclusively on the wing. The falcon climbs high above its quarry, then stoops at tremendous speed and strikes with clenched talons, the impact alone often killing or stunning the target. It then follows the falling bird down to finish the kill or catches it in the air. This aerial ambush is why open country, coastlines, and cliff edges suit the peregrine so well.


Where peregrines live

The peregrine is one of the most widely distributed birds on Earth, breeding on every continent except Antarctica and on many oceanic islands. Traditional nest sites are ledges on sea cliffs and rocky crags, but the species has adapted remarkably to human landscapes. Tall buildings, bridges, cathedrals, and power stations now serve as artificial cliffs, and city pigeons provide an abundant food supply. This flexibility has helped urban peregrine populations thrive across Britain and beyond.


Nesting and young

Peregrines do not build a true nest; instead the female scrapes a shallow hollow on a cliff ledge or building and lays three to four reddish-brown eggs. Both parents share incubation over roughly a month, and the chicks, called eyases, hatch covered in white down. The young fledge at around six weeks but depend on their parents for weeks afterwards as they learn to hunt. Peregrines often mate for life and return to the same nesting site year after year.


Recovery from near extinction

In the mid-20th century, peregrine populations crashed across Europe and North America as the pesticide DDT thinned their eggshells, causing them to break during incubation. After DDT was banned and captive-bred birds were released into the wild, numbers rebounded strongly. Today the peregrine is listed as Least Concern by the IUCN and is widely regarded as one of conservation's great success stories. Its comeback into city centres has made it one of the most watchable birds of prey.

What WARN Does

WARN does not run a dedicated peregrine falcon programme — this guide is part of the World Animal Rescue Network's free educational library. The peregrine falcon is currently widespread and not globally threatened, and this guide helps readers understand the pressures that can change that. Building public understanding of species like the peregrine falcon supports the broader conservation awareness that underpins WARN's partner-led rescue work across its network.

If clear, science-based wildlife guides like this help you understand and value animals, please consider supporting the World Animal Rescue Network's educational and rescue work so we can keep producing them.

Peregrine Falcon: Frequently Asked Questions

How fast can a peregrine falcon fly?

In its hunting dive, or stoop, a peregrine falcon can exceed 380 km/h (240 mph), making it the fastest animal on the planet. In ordinary flapping flight it is much slower; the record speed applies only to the near-vertical plunge onto prey.

What do peregrine falcons eat?

Peregrines are carnivores that feed almost entirely on other birds, such as pigeons, ducks, starlings, and waders, which they catch in mid-air. They occasionally take bats or small mammals, but birds caught on the wing make up the bulk of their diet.

Where do peregrine falcons live?

Peregrine falcons are found on every continent except Antarctica, from Arctic tundra to tropical coasts. They nest on sea cliffs and rocky crags, and increasingly on tall buildings, bridges, and cathedrals in towns and cities.

How long do peregrine falcons live?

Wild peregrine falcons can live up to about 15 years, though many die young in their first year. Birds that survive to adulthood and hold a good territory can breed for a decade or more.

Are peregrine falcons endangered?

No. The peregrine falcon is listed as Least Concern by the IUCN. Populations collapsed in the mid-1900s because of the pesticide DDT, but after it was banned the species recovered strongly and is now widespread again.

How big is a peregrine falcon?

The peregrine is a crow-sized raptor about 0.5 m long, weighing around 0.9 kg, with a wingspan of roughly 0.9 to 1.1 m (3 to 3.6 ft). As with most birds of prey, females are noticeably larger than males.

Are peregrine falcons dangerous?

Peregrine Falcons are not generally dangerous to people. The peregrine falcon (Falco peregrinus) is a crow-sized bird of prey found on every continent except Antarctica, making it one of the most widespread birds in the world. Give wild individuals space and do not corner or handle them.
