Peregrine Falcon (Falco peregrinus) lives in open country and urban cliffs across Every continent except Antarctica. Its conservation status is Least Concern.

A real field recording of the Peregrine Falcon, made in the wild.
The peregrine falcon occupies almost every continent, being present from the Arctic tundra down to tropical regions. It is absent only from extreme polar zones, very high mountains and most tropical rainforests, and the only ice-free landmasses where it does not occur are the islands of New Zealand. This near-global distribution makes it the world's most widespread raptor.
In urban areas the peregrine treats skyscrapers like natural cliffs, building its nest in a scrape on tall buildings. This behaviour lets it exploit the plentiful pigeons and ducks that thrive in cities, with feral pigeons providing a reliable staple food. The species' adaptability to human structures and abundant prey has turned cities into major breeding grounds.
Peregrine falcons show marked sexual dimorphism, with females considerably larger than males. Females can be up to 30 % larger and often weigh about 50 % more than their breeding partners. Male weights range from 330 to 1 000 g, while females range from 700 to 1 500 g, so a typical pair may differ by several hundred grams.
Genetically the Barbary falcon is almost identical to other peregrines, differing by just 0.6-0.8% of its DNA, a gap so small it points to a very recent evolutionary split. Scientists link that divergence to the climatic upheavals of the Last Ice Age, when isolated populations began to drift apart. Today taxonomists recognise only 18 or 19 regional subspecies of Falco peregrinus, the Barbary form being one of them.
The dark patch of feathers beneath a peregrine's eye is known as the malar stripe, a distinctive facial marking. A worldwide photographic analysis in 2021 revealed that birds living in sunnier locales possess a noticeably broader stripe. Researchers concluded that this enlargement reduces glare, sharpening the falcon's sight during high-light hunting. By cutting reflected light, the stripe gives the raptor a clearer view of fast-moving prey against bright skies.

As the peregrine falcon slices through the urban canyon, its sleek, slate-grey form blurs into a mesmerizing dance of speed and agility, defying the concrete jungle with each effortless swoop and dive. With wings tucked tight, it plunges towards its unsuspecting prey, a testament to the relentless power of evolution, where millennia of refinement have honed the art of the hunt to a breathtaking, heart-stopping precision. In this fleeting moment, the peregrine embodies the very essence of wild beauty, a symphony of feather and wind that transcends the steel and stone landscape below.
