The European robin (Erithacus rubecula), known simply as the robin or robin redbreast in Ireland and Britain and by its older name ruddock, is a small insectivorous passerine bird that belongs to the chat subfamily of the Old World flycatcher family. About 12.5–14.0 cm (5.0–5.5 inches) in length, the male and female are similar in colouration, with an orange breast and face lined with grey, brown upper-parts and a whitish belly. It is found across Europe, east to Western Siberia and south to North Africa; it is sedentary in most of its range except the far north.
The term robin is also applied to some birds in other families with red or orange breasts. These include the American robin (Turdus migratorius), a thrush, and the Australasian robins of the family Petroicidae, the relationships of which are unclear.
Taxonomy[]
The European robin was described by Carl Linnaeus in 1758 in the 10th edition of his Systema Naturae under the binomial name Motacilla rubecula. Its specific epithet rubecula is a diminutive derived from the Latin ruber 'red'. The genus Erithacus was introduced by French naturalist Georges Cuvier in 1800, giving the bird its current binomial name E. rubecula. The genus name Erithacus is from Ancient Greek and refers to an unknown bird, now usually identified as robin.
The distinctive orange breast of both sexes contributed to the European robin's original name of "redbreast", orange as a colour name being unknown in English until the 16th century, by which time the fruit had been introduced. In the 15th century, when it became popular to give human names to familiar species, the bird came to be known as robin redbreast, which was eventually shortened to robin. As a given name, Robin is originally a diminutive of Robert. Other older English names for the bird include ruddock and robinet. In American literature of the late 19th century, this robin was frequently called the English robin. Dutch roodborstje, French rouge-gorge, German Rotkehlchen, Italian pettirosso, Spanish petirrojo and Portuguese pisco-de-peito-ruivo all refer to the distinctively coloured front.
The genus Erithacus previously included the Japanese robin and the Ryukyu robin. These east Asian species were shown in molecular phylogenetic studies to be more similar to a group of other Asian species than to the European robin. In a reorganisation of the genera, the Japanese and the Ryukyu robins were moved to the resurrected genus Larvivora leaving the European robin as the sole member of Erithacus. The phylogenetic analysis placed Erithacus in the subfamily Erithacinae, which otherwise contained only African species, but its exact position with respect to the other genera was not resolved.
The genus Erithacus was formerly classified as a member of the thrush family (Turdidae) but is now considered to belong to the Old World flycatcher family (Muscicapidae), specifically to the chats (subfamily Saxicolinae) which also include the common nightingale.
Description[]
The adult European robin is 12.5–14.0 cm (5.0–5.5 in) long and weighs 16–22 g (9/16–13/16 oz), with a wingspan of 20–22 cm (8–9 in). The male and female bear similar plumage; an orange breast and face (more strongly coloured in the otherwise similar British subspecies E. r. melophilus), lined by a bluish grey on the sides of the neck and chest. The upperparts are brownish, or olive-tinged in British birds, and the belly whitish, while the legs and feet are brown. The bill and eyes are black. Juveniles are a spotted brown and white in colouration, with patches of orange gradually appearing.
Habitat[]
The robin occurs in Eurasia east to Western Siberia, south to Algeria and on the Atlantic islands as far west as the Central Group of the Azores and Madeira. It is a vagrant in Iceland. In the southeast, it reaches Iran the Caucasus range. Irish and British robins are largely resident but a small minority, usually female, migrate to southern Europe during winter, a few as far as Spain. Scandinavian and Russian robins migrate to Britain and western Europe to escape the harsher winters. These migrants can be recognised by the greyer tone of the upper parts of their bodies and duller orange breast. The European robin prefers spruce woods in northern Europe, contrasting with its preference for parks and gardens in Ireland and Great Britain.
In southern Iberia, habitat segregation of resident and migrant robins occurs, with resident robins remaining in the same woodlands where they bred.
Attempts to introduce the European robin into Australia and New Zealand in the latter part of the 19th century were unsuccessful. Birds were released around Melbourne, Auckland, Christchurch, Wellington and Dunedin by various local acclimatisation societies, with none becoming established. There was a similar outcome in North America, as birds failed to become established after being released in Long Island, New York in 1852, Oregon in 1889–1892, and the Saanich Peninsula in British Columbia in 1908–1910.
Ecology[]
The robin is diurnal, although it has been reported to be active hunting insects on moonlit nights or near artificial light at night. Well known to British and Irish gardeners, it is relatively unafraid of people and drawn to human activities involving the digging of soil, in order to look out for earthworms and other food freshly turned up. Indeed, the robin is considered to be a gardener's friend and for various folklore reasons the robin would never be harmed. In continental Europe on the other hand, robins were hunted and killed as with most other small birds, and are more wary. Robins also approach large wild animals, such as wild boar and other animals which disturb the ground, to look for any food that might be brought to the surface. In autumn and winter, robins will supplement their usual diet of terrestrial invertebrates, such as spiders, worms and insects, with berries and fruit. They will also eat seed mixtures and suet placed on bird-tables.
Male robins are noted for their highly aggressive territorial behaviour. They will fiercely attack other males and competitors that stray into their territories and have been observed attacking other small birds without apparent provocation. There are instances of robins attacking their own reflection. Territorial disputes sometimes lead to fatalities, accounting for up to 10% of adult robin deaths in some areas.
Because of high mortality in the first year of life, a robin has an average life expectancy of 1.1 years; however, once past its first year it can expect to live longer and one robin has been recorded as reaching 19 years of age. A spell of very low temperatures in winter may also result in significant mortality. This species is parasitised by the moorhen flea (Dasypsyllus gallinulae) and the acanthocephalan Apororhynchus silesiacus.
