The Hermit Thrush is the only member of its genus to spend the winter in North America. It changes its diet from eating nearly entirely insects in summer to one of equal parts insects and fruit in winter.

Cool Facts

• In the Appalachian Mountains the Hermit Thrush is displaced at lower elevations by the Veery and at higher elevations by Swainson's Thrush, leaving the middle altitudes for the Hermit Thrush.

• East of the Rocky Mountains the Hermit Thrush usually nests on the ground. In the West, it is more likely to nest in trees.

Description

• Size: 14-18 cm (6-7 in)
• Wingspan: 25-29 cm (10-11 in)
• Weight: 23-37 g (0.81-1.31 ounces)

• Medium-sized thrush.
• Brown back, reddish tail.
• Black spots on chest.
• Thin white eyering.
• Cocks tail up and flicks wings frequently; lifts tail up quickly, lowers it slowly.

• Bill pale at base, tip black.
• Eastern and northern birds more reddish, grayer in West; intermediate along Pacific Coast.

Sex Differences

Sexes alike

Immature

Like adult.

Similar Species

• Browner races of Swainson's Thrush similar, but have buffy eyering and a strong buffy wash to lower cheeks and breast, and tail does not contrast strongly with back.
• Gray-cheeked and Bicknell's thrushes have only a partial eyering, and the tail does not contrast as sharply with the back. The Bicknell's Thrush may have a chestnut tail, but not as bright rufous.

Sound

Song a melodious, fluty warble, mostly on one pitch, starting with a clear whistled note.
