What is a "robin"?

A robin is a small, plump bird that is familiar in gardens throughout Europe and North America. It is easily recognized by its bright orange-red breast and brownish-grey upper parts, which make it a popular subject for Christmas cards and other festive images. The robin is a member of the thrush family known for its melodic and cheerful song, often delivered from a high perch in a tree or shrub. Robins are also well known for their territorial behavior, and will fiercely defend their feeding and nesting areas against other birds. They are primarily insectivorous, but will also feed on fruits and seeds, and are attracted to bird tables and feeders in the winter months. The robin is a year-round resident in many parts of its range, but some populations migrate southwards during the colder months.
