The true thrushes are medium-sized mostly insectivorous or omnivorous birds in the genus Turdus of the thrush family Turdidae.
The genus has a cosmopolitan distribution, with species in the Americas, Europe, Asia, Africa and Australia. Several species have also colonised some oceanic islands, and two species have been introduced to New Zealand. Some New World species are called robins, the most famous of which is the American Robin. Several species are migratory.
While some species are often split out of Turdus, the two small thrushes formerly separated in Platycichla by many authors are usually placed in the present genus again in recent years.
Thrushes are plump, soft-plumaged, small to medium-sized birds, inhabiting wooded areas, and often feed on the ground or eat small fruit. They range in size from the Forest Rock-thrush, at 21 g (0.74 oz) and 14.5 cm (5.7 in), to the Blue Whistling-thrush, at 178 g (6.3 oz) and 33 cm (13 in). Most species are grey or brown in colour, often with speckled underparts.
They are insectivorous, but most species also eat worms, land snails, and fruit. Many species are permanently resident in warm climes, while others migrate to higher latitudes during summer, often over considerable distances.
Thrushes build cup-shaped nests, sometimes lining them with mud. They lay two to five speckled eggs, sometimes laying two or more clutches per year. Both parents help in raising the young.
The songs of some species, including members of the genera Catharus, Myadestes, and Turdus, are considered to be among the most beautiful in the avian world.
