Don't expect to see many robins eating at your bird feeder in spring (although they do like suet). They prefer a diet of worms, grasshoppers, termites, and grubs, and will be looking for them in lawns and leaf litter. In autumn and winter they like fruit and berries.
In early spring, robins usually build their nests in evergreen trees. Later, they nest in deciduous trees. The females build the nests from mud and grass.
The American robin was (mis)named by early English settlers, probably because it has the orange-breast of the robin of England. Although both are members of the thrush family (you can see the resemblance in the speckled-breasted youngsters), they're not closely related.
In the wild, robins can live well into their teens-if they can avoid cats, their main predator.
