Gray-cheeked Thrush
Gray-cheeked Thrush
Catharus minimus
At a Glance
All the brown-backed thrushes can be shy and hard to see, but the Gray-cheek is perhaps the most elusive. During migration it hides in dense woods, slipping away when a birder approaches. On its far northern nesting grounds it may be more easily seen, especially in late evening, when it sings from treetops.

Behavior
Eggs
4, sometimes 3-5, perhaps rarely 6. Pale blue, with vague brown spots, sometimes almost unmarked. Incubation is by female, 12-14 days.
Young
Both parents feed nestlings. Young leave nest about 11-13 days after hatching.
Feeding Behavior
Forages mostly on the ground, hopping about under cover of dense thickets. Sometimes seen feeding on berries up in shrubs or trees.
Diet
Mostly insects and berries. Diet through the year is not known in detail. In North America, feeds on a variety of insects, including beetles, caterpillars, ants, wasps, fly larvae, and many others; also spiders and some other invertebrates. Also eats many berries and wild fruits. Winter diet in tropics poorly known.
Nesting
Male arrives first on breeding grounds and establishes territory, defending it by singing. In courtship, male pursues female in swift flight among the trees. Nest: Often placed very low or even on the ground; usually less than 10' up, sometimes up to 24'. Ground nests are often among bases of willow or alder shoots, while higher nests may be against trunk of conifer at base of branches. Nest (built by female) is a well-made open cup of grass, moss, twigs, weeds, strips of bark, sometimes with some mud added; lined with fine grass and rootlets.
Climate Vulnerability
Conservation Status
Southern breeding populations of Gray-cheeks may be declining.
