Hirundo rustica
SUBFAMILY
Hirundinae
TAXONOMY
Hirundo rustica Linnaeus, 1758. Six subspecies are recognized.
OTHER COMMON NAMES
English: Chimney swallow, European swallow, house swallow, swallow; French: Hirondelle de cheminée; German: Rauchschwalbe; Spanish: Golondrina Bermeja.
PHYSICAL CHARACTERISTICS
7.5 in (19 cm); 0.6 oz (17 g). The back is glossy blue-black, the throat and belly rusty brown, and there is a brighter rusty-red patch on the forehead. The tail is deeply forked. The six geographic subspecies vary somewhat in coloration.
DISTRIBUTION
The most widespread species of swallow. It breeds in northern regions of Eurasia, North America, and northern North Africa. It migrates to winter in more southern regions of its range, including northern and central South America, central and southern Africa, and South and Southeast Asia.
HABITAT
Forages in open areas, often close to water. Nests primarily on built structures, as well as natural cliffs and caves.
BEHAVIOR
Begins to migrates south at the end of August, but particularly in the first half of September. Before they depart and while resting during migration, they may aggregate into large flocks, often with other species of swallows. Late migrants may persist until late October or early November. Has a loud, twittering song and is perhaps the most talented singer in the family. Its contact call, used to attract and connect with others, is a high-pitched, loud, repeated weet.
FEEDING ECOLOGY AND DIET
Feeds on insects caught in flight.
REPRODUCTIVE BIOLOGY
Monogamous. Builds a cup-shaped nest of mud and some plant fibers, often attached to a building beneath a shading overhang, and sometimes inside if there is easy access. Its natural nest sites are cliffs, cave walls, and clefts in the ground. It usually takes about eight days to build a new nest, but in unfavorable weather this may be as long as four weeks. The nest is lined mostly with feathers. A nest may be used for a decade or longer, being refurbished each year. The clutch is typically three to six eggs. However, clutches laid later in the season have fewer eggs. Generally only the female incubates, although the male may also participate, especially in the American subspecies. The young hatch asynchronously after 11–18 days of incubation and are fledged after 15–23 days. Generally breeds once or twice per season, rarely three times.
CONSERVATION STATUS
Not threatened. A widespread and abundant species.
SIGNIFICANCE TO HUMANS
The barn swallow is a popular bird for many people. In parts of Europe it is considered an omen of good luck and a harbinger of spring. It has lived for millennia in close association with humans, and has likely benefited from this relationship and become more abundant than in former times. This bird is welcomed by farmers because it eats many insect pests that affect livestock and crops.
Similar species: Most other N. American swallows have notched (not deeply forked) tails. (1) Cliff Swallow is colonial, building mud jugs under eaves or cliffs. (2) See Cave Swallow.
Voice: A soft vit or kvik-kvik, vit-vit. Also szee-szah or szee. Anxiety note, a harsh, irritated ee-tee or keet. Song, a long musical twitter interspersed with gutturals.
Range: Widespread in N. Hemisphere. Winters Costa Rica to Argentina, Africa, s. Asia.
Habitat: Open or semi-open land; farms, fields, marshes, lakes; often perches on wires; usually near habitation. Builds its cuplike nest inside barns, not in tight colonies under eaves, like Cliff Swallow.
The noun has one meaning:
Meaning #1:
common swallow of North America and Europe that nests in barns etc.

| Hirundo rustica Linnaeus, 1758 |
The Barn Swallow (Hirundo rustica) is a small migratory passerine bird found in Europe, Asia, Africa and the Americas. It has a long, deeply forked tail and curved, pointed wings. It is often just called Swallow in Europe, although the term 'swallow' refers more widely to various members of the family Hirundinidae. The Barn Swallow makes their nests out of mud.
The nominate European subspecies H. r. rustica has dark blue-black upperparts, off-white underparts and a small patch of red on the throat, with a broad dark blue-black breast band separating the red throat from the off-white underparts. It breeds in Europe and western Asia, as far north as the Arctic Circle, and migrating to Africa in winter.
The North American subspecies H. r. erythrogaster differs from the European subspecies in having redder underparts and a narrower, often incomplete dark breast band. It breeds throughout North America, migrating to South America in winter.
The Middle Eastern subspecies H. r. transitiva and the resident Egyptian subspecies H. r. savignii also have orange-red underparts, but with a broad dark breast band.
The Asian subspecies H. r. gutturalis, H. r. mandschurica, H. r. saturata, and H. r. tytleri are similar to the North American subspecies, with variably darker orange underparts (pale in gutturalis, darkest, deep orange-red, in saturata) and a narrower dark breast band; they breed in eastern Asia and winter in southern Asia and northern Australia.
Chip!
Barn Swallows are similar in habits to the other aerial insectivores, including the other related swallows and martins and the unrelated swifts (order Apodiformes). They are not particularly fast flyers (estimated at about 11 m/s[1]), but show remarkable manoeuvrability, necessary to feed on flying insects while airborne. They are often seen flying relatively low in open or semi-open areas. It is also estimated that they beat their wings approximately 15 times each second[1]
Barn Swallows build neat cup-shaped nests constructed of mud collected in their beaks. The inside of the nest is lined with grasses, feathers and other soft materials. They normally nest in accessible buildings such as stables or under bridges and wharves. Before these types of sites became common, they nested on cliff faces or in caves. The female typically lays 4 or 5 eggs. Both parents build the nest and feed the young. Barn Swallows will swoop and attack intruders that venture too close their nest, often coming within inches of the threat.
The numbers in North America increased during the 20th century with the increased availability of man-made nesting sites. In recent years, there has been an ongoing gradual decline in numbers in parts of Europe and North America, due to agricultural intensification reducing the availability of insect food. However, it remains widespread and fairly common in most parts of its range.
