Discover: Swift

The only time these birds land is for nesting, swifts spend most of their lives in the air, sleeping, feeding and mating in the sky.

  • Conservation status: Amber (Birds of Conservation Concern)
  • Measurements: Length: 16-17 cm, wingspan: 42-48 cm, weight: 36-50g.
  • When swifts are flying about in social groups, you should be able to hear their high pitched screaming calls to each other.

Swifts can tell the difference between hoverflies and stinging insects like bees and wasps, allowing them to take advantage of non-stinging insects with warning colours.
