The American robin (Turdus migratorius) is a migratory songbird of the true thrush genus and Turdidae, the wider thrush family. It is named after the European robin because of its reddish-orange breast, though the two species are not closely related, with the European robin belonging to the Old World flycatcher 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.According to some sources, the American robin ranks behind only the red-winged blackbird (and just ahead of the introduced European starling and the not-always-naturally-occurring house finch) as the most abundant extant land bird in North America.It has seven subspecies, but only T. m. confinis of Baja California Sur is particularly distinctive, with pale gray-brown underparts.

Behaviour:

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 eggs, beginning to breed shortly after returning to its summer range from its winter range. Its nest consists of long coarse grass, twigs, paper, and feathers, and is smeared with mud and often cushioned with grass or other soft materials. It is one of the first birds to sing at dawn, and its song consists of several discrete units that are repeated.

Diet:

The American robin's diet generally consists of around 40 percent small invertebrates (mainly insects), such as earthworms, beetle grubs, caterpillars and grasshoppers, and 60 percent wild and cultivated fruits and berries.Their ability to switch to berries allows them to winter much farther north than most other North American thrushes. They will flock to fermented Pyracantha berries, and after eating sufficient quantities will exhibit intoxicated behaviour such as falling over while walking. Robins forage primarily on the ground for soft-bodied invertebrates, and find worms by sight (and sometimes by hearing), pouncing on them and then pulling them up.Nestlings are fed mainly on worms and other soft-bodied animal prey. In some areas, robins, particularly of the coastal race T. m. caurinus, will feed on beaches, taking insects and small mollusks.

The robin uses auditory, visual, olfactory and possibly vibrotactile cues to find prey, but vision is the predominant mode of prey detection.It is frequently seen running across lawns picking up earthworms, and its running and stopping behaviour is a distinguishing characteristic. In addition to hunting visually, it also has the ability to hunt by hearing. Experiments have discovered that it can find worms underground by simply using its listening skills.It typically will take several short hops and then cock its head left, right or forward to detect movement of its prey. In urban areas, robins will gather in numbers soon after lawns are mowed or where sprinklers are in use.They also are attracted to freshly turned earth in gardens, where worms and grubs are abundant targets. Occasionally, they may visit bird feeders if meal worms or animal-fat suet is offered.
