- Hirundo rustica
Identification
17-19cm. Glossy blue-black above and on breast band. Forehead, chin and throat reddish-chestnut. Remainder of underparts creamy-white. The deeply forked tail is spotted white at the base.
Sexes alike, but female has shorter and broader tail streamers.
Juvenile: has shorter, blunt tail streamers, browner upperparts and a brownish-pink forehead and throat.
Similar Species
Juvenile Swallow lacks the white rump of a Northern House Martin.
Distribution
Breeds in the northern half of the globe. Abundant and widespread throughout the western Palearctic. Breeds from the British Isles, France and Iberia east to the Urals and Caspian. In the north found to 70° N on the Norwegian coast and breeds north to the White Sea in Russia. Breeds on the north Mediterranean coast and most islands, in Turkey and the Caucasus, across North-West Africa and in the Nile valley but only locally in the Middle East.
Small numbers regularly winter in southern Spain and North-West Africa but the majority of European birds winter in sub-Saharan Africa leaving breeding areas August-October and returning March-May. Middle Eastern and Egyptian birds are largely resident.
Vagrant north to Iceland (has bred), Faroe Islands (may breed annually), Svalbard, Bear Island and Jan Mayen, also on the Azores, these birds may have originated in North America.
Taxonomy
Six different subspecies occur, with typical birds of several of these separable in the field.
In Western Palearctic, nominate race is found over most of range, replaced by transitiva in southern Turkey, Syria and Lebanon, Israel and western Jordan, with pinkish to orange underparts and savignii in Egypt with dark red-brown underparts, both slightly larger than nominate.
In Asia, tytleri belongs to the same group as the above, while further east, the gutturalis group includes the mandschurica subspecies; together these two subspecies breeds from eastern Himalayas to eastern Asia and migrates to southeast Asia and Australasia in winter.
North American race erythrogaster with reduced breast-band and rusty-buff underparts has possibly been recorded as a vagrant in Iceland.
Habitat
Mainly occurs on farmland with abundant flying insects attracted by livestock and nesting sites in farm buildings. Often breeds in rural villages but rarely in large towns. Highly gregarious on passage and frequently feeds over large water bodies.
Behaviour
Rarely perches in trees, but very inclined to sit on telegraph wires.
Gregarious, often seen feeding in the company of Martins and Swifts.
Flight
Fast, with clipped wing beats, often low to the ground. Will fly across a water surface and drink whilst on the move.
Breeding
Barn Swallows have been studied extensively for what influences sexual selection etc. In short, in Europe a male with long tail streamers seems to do well. In North America, the colour of the underparts, especially the breast area, seems to be important for the breeding success of a male, with dark colour being advantagous (length of tail streamers still probably is important).
It nests inside buildings such as barns and stables, or under bridges and wharves. Usually the female builds the cup-shaped nest, placed on a beam or against a suitable vertical projection. It is made from mud pellets and lined with grasses, feathers or other soft materials. 4-5 reddish-spotted white eggs are laid, and are incubated by the female for 14-19 days; the young fledge 18-23 days later.
Diet
The diet consists almost entirely of flying insects.

In Culture
An old country lore states "Swallows flying high - going to be dry".
