Common Swift in flight

A dark, 'boomerang'-shaped bird that arrives in the UK in late spring and leaves at the end of summer.

Seasonal Behaviour:

On warm summer evenings, you might hear loud 'screaming' sounds from high in the sky. This is a group of swifts chasing each other very fast, known as a 'screaming party'. They are very fast, noisy flyers.

💡 Fun Facts

  • Swifts spend almost their whole lives in the air. They eat, drink, and even sleep while flying!
  • The only time a swift ever lands is to build a small nest (under roof tiles or in cliffs) and lay its eggs.
  • They eat flying insects, catching them in their wide mouths like a net.

📅 Through the Year

Name Story

Apus apus

means “the footless one”

a traditional story'Footless' comes from an old belief, not the truth — swifts do have tiny feet; they simply cannot walk on them. The name captures the legend rather than the biology.
What does its name mean?
  • Apus — without feetGreek a- 'without' + pous 'foot'
  • apus — repeats the genus, so the name says 'footless' twiceGreek

People once believed swifts had no feet at all, because you almost never see one perched — they eat, sleep and even mate on the wing, landing only to nest. They do have tiny feet, just enough to cling to a wall, but never to walk.
