Thrushes and Allies
Ixoreus naevius
The Varied Thrush is a striking, robin-sized songbird of western North America, known for its bold plumage and haunting, ethereal song. Often elusive, this species typically inhabits dense, moist forests, where its distinctive calls echo through the trees. It is a member of the thrush family, Turdidae, and is the sole member of its genus, *Ixoreus*.
Typical adult measurements.
Individuals and populations vary.
01 / The telltale details
Start with shape and behavior. Then look for the smaller details.
Males display a dark blue-gray back, head, and rump, with a vibrant burnt-orange breast and belly. A prominent sooty-black breast band and an orange eyebrow stripe are also characteristic.
Females share the same general pattern as males but are duller, with paler gray-brown upperparts and a less defined, often gray or absent, breast band.
Both sexes have blackish wings adorned with two orange wing bars and orange edging on the flight feathers.
Juveniles show a mottled chest and an incomplete breast band, often with orange and dusky speckles, but retain the adult wing pattern.
02 / A place in the world
Varied Thrushes prefer dark, wet, mature coniferous and mixed forests, particularly those with dense understories of ferns, shrubs, and mosses. They are often found near streams and rivers. In winter, they may move to lower elevations, including parks and gardens.
This species breeds from Alaska and the Yukon south through western Canada, northwestern Montana, Idaho, Washington, and most of Oregon to extreme northwestern California. In winter, they can be found from coastal Alaska southward through California to northern Baja California, with some individuals occasionally straying eastward across North America.
Varied Thrushes are short-distance migrants, though northern breeding populations undertake longer migrations south. Coastal populations in the Pacific Northwest may be more locally migratory, often moving to lower elevations in winter. Irruptive movements can lead to sightings far outside their typical range.
03 / Listen a little closer
The song is a distinctive, slow, ringing whistle, often described as eerie or haunting, consisting of a single, drawn-out note repeated at different pitches after deliberate pauses. Calls include a low "took."
04 / The life behind the feathers
During the breeding season, their diet primarily consists of insects and other arthropods found in leaf litter. In fall and winter, they shift to consuming a variety of berries, seeds, and nuts, including acorns.
These thrushes primarily forage on the ground, often flipping leaf litter to uncover insects and other invertebrates. They also consume fruits and berries from trees and shrubs, especially in colder months.
The Varied Thrush typically builds an open cup nest in a small conifer, or sometimes a deciduous tree, usually 2-4.5 meters above the ground. The nest is constructed with an outer layer of twigs, leaves, and bark, a middle layer of rotten wood, moss, and mud, and an inner lining of fine grasses and mosses. The female incubates a clutch of 2-5 (usually 3-4) pale blue, sparsely spotted eggs for about 12-14 days.
Varied Thrushes are generally shy and solitary birds, often remaining hidden within dense foliage. While typically aggressive towards other birds, they may occasionally join American Robins to forage for berries or earthworms on lawns during winter. Males defend breeding territories through song.
One more reason to pay attention
The Varied Thrush's scientific name, *Ixoreus naevius*, refers to mistletoe berries and the bird's varied, or discolored, markings.
Varied Thrush populations exhibit a cyclical pattern, with peaks in abundance occurring approximately every two years.
The oldest recorded Varied Thrush lived to be at least 4 years and 9 months old.
