Song or voice of the Red-rumped Swallow

Its song is a short, sweet twitter, of less volume than the Barn Swallow’s. It also gives the typical calls of swallows, although in some ways they recall those of some sparrows and buntings.

Flight of the Red-rumped Swallow

It has an agile, fast, acrobatic flight. It hunts with chasing flights that are slower and more gliding than the Barn Swallow’s.

  1. It is often seen near bridges and rock faces, in warm areas of Mediterranean vegetation tied to watercourses.

  2. It hunts flies, mosquitoes, flying ants and small beetles in acrobatic chasing flights, slower and more gliding than the Barn Swallow's.

  3. Its nest is a hemisphere of mud pellets with an entrance tunnel, stuck under a roof, an eave or a rocky overhang.

Identification of the Red-rumped Swallow

Similar in appearance to the Barn Swallow, it has a black back with bluish sheen and a dirty white belly, with orange flanks and some faint streaks. Its most characteristic features are the orange nape and face, the same colour as the rump. The long, pointed wings also show orange tones on the front underside, and the very long, very forked tail is uniform black above and below. It has short, unfeathered legs, a very wide mouth and a short, flat, black bill. The two sexes are alike. It is often seen near bridges and rock faces.

Habitat and distribution of the Red-rumped Swallow

It breeds over much of Asia and in small areas of Africa and southern Europe, where it continues to spread north. There are sedentary populations, but most are migratory, and the European ones winter in Africa. Ten subspecies are recognised, and taxonomic revisions based partly on the shape of the nest place it in the genus «Cecropis». In Spain the subspecies «rufula» lives, with little streaking on the breast and belly, which some lists now treat as a separate species.

It occupies the Peninsula, Ceuta and Melilla, and is spread almost uniformly across Andalusia, Extremadura, Madrid, Toledo, Ciudad Real, Ávila, Salamanca and Zamora, with scattered cores across the rest, above all along the Mediterranean coast. It also breeds in Galicia, Asturias, Cantabria, Mallorca and Menorca. The first Spanish record is from 1921, in Cádiz, and since then its expansion has been steady, very intense between 1950 and 1980.

It prefers warm areas of Mediterranean vegetation, woods and dehesas, scrub and grasslands, tied above all to rivers and with rock faces to breed on. For that it also makes itself at home on country structures, above all bridges, underpasses beneath roads and abandoned rural buildings, and where it is most abundant it begins to occupy houses in villages and small towns. It is more numerous between 500 and 1,000 metres, although nests at 1,600 have been recorded.

Spanish birds winter in Africa, presumably in the west of the Sahel. The first return in February, and the mass arrival is in March and April. They leave the nests in August and September, gather in small groups and cross the Strait mainly between the second half of September and the first half of October.

Etymology of the Red-rumped Swallow

According to Wikipedia, the genus «Cecropis», created by Friedrich Boie in 1826, comes from ancient Greek and means «Athenian woman», and the epithet «daurica» refers to Dauria, a mountainous region east of Lake Baikal, in Russia. The western population, which is ours, was described in 1835 as «Hirundo rufula», from Latin «rufulus», «reddish». In other languages it is called «oreneta cua-rogenca» in Catalan, «anduriña dáurica» in Galician, «enara ipurgorria» in Basque and «red-rumped swallow» in English1.

Population of the Red-rumped Swallow

In the 2021 European Red List of Birds the European breeding population is estimated at between 2,860,000 and 6,680,000 mature individuals, with a stable trend. The Spanish population is calculated at around 1,100,000 birds, with its best areas in Andalusia, Castilla-La Mancha and Extremadura, and the SACRE programme shows moderate growth between 1998 and 2018.

No conservation problems are known for it, although it would be affected by the general threats of pesticide abuse, air pollution, disturbance during breeding and the destruction of nests.

Nest of the Red-rumped Swallow

Both sexes build it in some 10–15 days: a hemisphere of mud pellets with an entrance tunnel, like an igloo turned upside down. They almost always stick it horizontally under a roof, an eave or a rocky overhang, and repair and reuse it for several years. It breeds alone or in small scattered colonies, and is faithful to its breeding site.

Courtship and breeding of the Red-rumped Swallow

The breeding period begins in mid-April and ends in September. It normally makes two clutches, sometimes three, and the number of eggs falls from one to the next: in Extremadura the average is 4.5 eggs in the first, 3.8 in the second and 3.6 in the third. The eggs, cream with reddish spots, are incubated by both sexes for some 15 days. The chicks leave the nest at about 27 days, and on average 3.5 chicks fly per brood.

Diet of the Red-rumped Swallow

It eats flies, mosquitoes, flying ants, wasps, bugs and small beetles, which it hunts in acrobatic chasing flights, slower and more gliding than the Barn Swallow’s. It usually hunts alone or in small groups, sometimes alongside other swallows and martins.

Curious facts about the Red-rumped Swallow

Its presence has opened the door to another African colonist, the White-rumped Swift, which breeds in its nests1. And that it was the shape of the nest, among other reasons, that led to its separation from the genus «Hirundo» of the Barn Swallow.

The Red-rumped Swallow in Cabañeros

The habitat pages of this website do not mention it, and we have not found any other published source on it in the Park. GBIF.org records 45 observations of the Red-rumped Swallow in Cabañeros and its surroundings.

How to tell them apart

It is not clearly similar1. Like the Red-rumped Swallow, the Western House Martin is a hirundine that builds its nest with mud.
