Alpine Swift (Tachymarptis melba syn. Apus melba)

Alpine Swift (Tachymarptis melba syn. Apus melba) The Alpine Swift (Tachymarptis melba, syn. Apus melba) is a small bird, superficially similar to a large Barn Swallow or House Martin with whom it is completely unrelated.

These birds have very short legs which they use only for clinging to vertical surfaces. The scientific name comes from the Ancient Greek ?????, apous, meaning "without feet". They never settle voluntarily on the ground.

Distribution / Range

Alpine Swifts breed in mountains from southern Europe to the Himalaya.

Like Common Swifts, they are strongly migratory, and winter much further south in southern Africa. They wander widely on migration, and are regularly seen in much of southern Europe and Asia.

The species seems to have been much more widespread during the last ice age, with a large colony breeding for example at Komarowa Cave near Cz?stochowa, Poland, around 40,000-20,000 years ago (Tomek and Boche?ski 2005).


Alpine Swifts are easily identified by their large size. Their wingspan is 55cm compared to the 42cm of Common Swifts. They are black except for a white belly and throat, with a dark neck band separating the white areas.

They have a short forked tail and very long swept-back wings that resemble a crescent or a boomerang but may (as in the image) be held stretched straight out. The flight is slower and more powerful than that of their smaller relative.

Calls / Vocalizations

Its call is described as a drawn-out twittering.

Alpine Swift (Tachymarptis melba syn. Apus melba) Breeding / Nesting

Alpine Swifts build their nests in colonies in a suitable cliff hole or cave, laying 2-3 eggs. A swift will return to the same site year after year, rebuilding its nest when necessary. These birds pair for life.

Young swifts in the nest can drop their body temperature and become torpid if bad weather prevents their parents from catching insects nearby.

Feeding / Diet

Alpine Swifts spend most of their lives in the air, living on the insects they catch in their beaks. They drink on the wing, but roost on vertical cliffs or walls.


This species, and the related African species Mottled Swift, are sometimes separated into the genus Tachymarptis, but genetic evidence suggests that this would leave the remainder of Apus paraphyletic.

In the Sibley-Ahlquist taxonomy, the old order Apodiformes is split. Swifts remain in that order, but hummingbirds are put into a new order, Trochiliformes. This is not generally accepted due to being contradicted by fossil evidence.
