The American robin (Turdus migratorius) is a migratory songbird of the true thrush genus and Turdidae, the wider thrush family. The American robin is widely distributed throughout North America, wintering from southern Canada to central Mexico and along the Pacific Coast. It is the state bird of Connecticut, Michigan, and Wisconsin. The American robin is the most abundant landbird in North America (with 370Â million individuals) The American robin is active mostly during the day and assembles in large flocks at night. Its diet consists of invertebrates (such as beetle grubs, earthworms, and caterpillars), fruits, and berries. It is one of the earliest bird species to lay its eggs, beginning to breed shortly after returning to its summer range from its winter range. The adult robin's main predator is the domestic cat other predators include hawks and snakes. When feeding in flocks, it can be vigilant, watching other birds for reactions to predators.
