Robin

The robin, once almost exclusively associated with Christmas cards and picturesque scenes, is now almost ubiquitous all year round.

It was officially adopted as Britain's National Bird in 1960, helped by its fearless approach to humans and the fact that both males and females have the same, instantly-recognisable plumage.

The birds are highly territorial and aggressive, so it's no surprise that although 79 per cent of gardens have them, there are only 1.26 birds per garden. It does, however, counteract that aggression with almost year-round singing, escpecially in winter.
