The European robin (Erithacus rubecula), known simply as the robin or robin redbreast in Great Britain and Ireland, is a small insectivorous passerine bird that belongs to the chat subfamily of the Old World flycatcher family. 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.
It is about 12.5–14.0 cm (4.9–5.5 in) 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.
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 continental European robins that migrate during winter prefer spruce woods in northern Europe, contrasting with its preference for parks and gardens in Great Britain.
In southern Iberia, habitat segregation of resident and migrant robins occurs, with resident robins remaining in the same woodlands where they bred.
