en European robin
The European robin is a small insectivorous passerine bird, specifically a chat, that was formerly classified as a member of the thrush family but is now considered to be an Old World flycatcher. 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.
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 it 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 that disturb the ground, such as wild boar, 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 placed on bird-tables.
Robins may choose a wide variety of sites for building a nest. In fact, anything which can offer some shelter, like a depression or hole may be considered. As well as the usual crevices, or sheltered banks, other objects include pieces of machinery, barbecues, bicycle handlebars, bristles on upturned brooms, discarded kettles, watering cans, flower pots and even hats.
