Do Robins Migrate?
In short: Some robins migrate, but most robins in the UK stay year-round. However, some British birds fly to mainland Europe for winter, while some robins from northern and eastern Europe arrive here. So whilst the robin you see in your garden in January may be a year-round neighbour, not every winter robin is local.

Do UK robins leave in winter?
Most do not. Many spend the winter close to where they bred, and some defend the same garden or nearby patch throughout the colder months. This is why robins are familiar in the UK even at Christmas.
However, some do leave. Researchers have found robins ringed in Britain across the Channel in winter. Females are more likely than males to make these longer journeys, although many females stay too. A bird moving a few streets from where it hatched is not the same thing as migrating to another country.
Where do Britain's winter robins come from?
Britain also receives robins from northern and eastern Europe. Some spend the winter here; others stop on their way farther south. Their arrival is easiest to notice along the east coast in autumn, where several new robins may appear in hedges and coastal scrub after a night of migration.
This means the UK has robins year-round, but winter birds are a mix of residents and visitors.
When do robins migrate?
Robins begin arriving from Europe in September, with more arriving during October. Those that spend winter in Britain head back in spring. Because many UK robins never leave, no month sees robins disappear from the country.
Is the robin in my garden the same bird all year?
It might be. A robin that has a good feeding patch can stay nearby through winter. But another robin could take its place, and an ordinary view of an unmarked bird cannot tell you whether it was born locally or arrived from abroad.
You may hear that migrant robins look paler or are more nervous around people. These are unreliable clues. Robins vary as individuals, and a shy bird in an October hedge has not necessarily flown across the North Sea. Numbered rings, when birds are encountered again elsewhere, give much stronger evidence of where they have travelled.
