Physical description Click here for a physical description Common Swifts are relatively large swifts. Their plumage is all dark-grey, except a light-grey throat patch and mid-grey flight feathers. The entire body plumage has thin light-grey edges, leading to a finely scalloped appearance when seen close-up. Swifts, as the name suggests, are fast fliers; accordingly, their wings have the shape of a backward-bent sickle, which - together with the relatively short, prominently forked tail - distinguishes them from swallows. In-flight the very short legs are invisible.

Taxonomy, classification See Common Swift at Wikipedia .

Range, habitat, finding this species Click here for information on habitat and range The overall distribution of this species can be assessed, and specific locations where birds have been spotted can be found, based on individual sighting reports submitted by birdwatchers to ebird.org . The global distribution of the Common Swift is available HERE . Common Swifts are a strongly migratory species; except when breeding they are continuously on the wing. Their breeding grounds are along the north-western African coastal fringe, in all of Europe (except small parts of the northern coastline of Scandinavia), Asia Minor and mid- to high-latitude Asia (to about 70 degrees geographical latitude), reaching the eastern Russian coastline. In the South-east their breeding range extends through Syria, Iraq, Iran onwards into the southern half of Pakistan and the northern half of India, and into the Himalayas. They winter in/above all of southern Africa, to the South of the equator, except the very tip near the Cape of Good Hope. During their migration Common Swifts can also be found (in the air above) anywhere in Arabia and the northern half of Africa. During the breeding season Common Swifts will be found near suitable nest sites (rockfaces, ruins, houses, bridges, viaducts), in the vicinity of good hunting grounds (e.g. near water). Outside the breeding season their movements will be dominated by the availability of flying insects, which are often abundant in wetlands, especially stagnant water or in marshy river deltas.

Sightings Click here for sighting information We spotted Common Swifts in the Rheinaue near Kiedrich, Hessen, Germany, in May 2010. D. Wilczynska reports spotting Common Swifts near Brok, Masovia, Poland, in May 2016, where their calls have been recorded. J. Pires reports finding Common Swifts regularly in the area of Lisbon, the Tejo estuary and Mora, Evora, Portugal, where they nest every summer. M. Eaton reports spotting Common Swifts at Split, Croatia, in September 2019. In the past we used to see Common Swifts regularly in various parts of Germany (especially in low mountain ranges such as the Eifel).
