The Varied Thrush has a widespread nesting distribution throughout southern portions of the province, from the west coast of Vancouver Island east to the Rocky Mountains and north, in the interior at higher elevations, to the latitude of Quesnel (53°N). Further north, nesting reports are scattered and sparse. Most habitats in which nesting occurred were forested, including coniferous forest, mixed forest, and deciduous forest. Most nests were in trees, including coniferous and deciduous trees, followed by shrubs or vines. Nests in trees and shrubs were placed on branches, typically close to the trunk or near the top of the nest tree. The nest is a bulky cup of grass, moss, and rootlets, on a base of twigs. It is usually lined with fine grass, although leaves and shredded redcedar bark are also frequent components. Sizes of clutches ranged from 1 to 5 eggs, with a majority having 3 eggs.DA6 image Varied Thrush Ixoreus naevius
