Conservation status | Numbers seem to be holding up well. Winters farther north than other brown thrushes, less dependent on tropical forest for wintering. |
---|---|
Family | Thrushes |
Habitat | Conifer or mixed woods, forest floor; in winter, woods, thickets, parks. Breeding habitats vary in different regions; included are spruce woods, sphagnum bogs, dry pine woods, second growth in burns with standing dead trees, thickly wooded canyons, mountain forests of spruce and fir. In migration and winter found in any kind of woodland. |
Does much foraging on ground, picking up insects from leaf-litter or soil; also feeds up in shrubs and trees, often hovering momentarily while grabbing an insect or berry.
4, sometimes 3-5, rarely 6. Pale blue or greenish blue, occasionally flecked with brown or black. Incubation is by female, about 12 days.
Both parents feed nestlings. Young are ready to fly at about 12 days. Usually 1-2 broods per year, perhaps sometimes 3 in south.
Mostly insects and berries. Feeds on a variety of insects, including beetles, ants, caterpillars, true bugs, grasshoppers, crickets, and many others; also spiders, earthworms, rarely small salamanders. Also eats many berries, especially in winter; diet includes elderberries, pokeberries, serviceberries, grapes, mistletoe berries, and many others.
Male defends nesting territory by singing, especially in morning and evening. Nest site for nest varies with region. To the east and north, often on the ground, in a natural hollow on the side of a hummock and well hidden by overhanging branches or surrounding low vegetation. To the west, usually in a tree, especially a conifer, 3–12' above the ground. Nest (built by female alone) is a bulky, well made open cup of moss, weeds, twigs, bark strips, ferns, lined with softer materials such as pine needles, rootlets, and plant fibers.
Audubon’s scientists have used 140 million bird observations and sophisticated climate models to project how climate change will affect this bird’s range in the future.
Zoom in to see how this species’s current range will shift, expand, and contract under increased global temperatures.
Choose a temperature scenario below to see which threats will affect this species as warming increases. The same climate change-driven threats that put birds at risk will affect other wildlife and people, too.

Now that we know what constitutes a birb, it's time to break down the internet's other two nicknames for birds.
The voracious crawlers are now chewing through leaf litter in Minnesota and Chicago and disrupting understory where some birds nest.
