Brown Thrasher
Brown Thrasher
Toxostoma rufum
At a Glance
The big, foxy-red Brown Thrasher is a familiar bird over much of the east. Sometimes it forages boldly on open lawns; more often it scoots into dense cover at any disturbance, hiding among the briar tangles and making loud crackling callnotes. Although the species spends most of its time close to the ground, the male Brown Thrasher sometimes will deliver its rich, melodious song of doubled phrases from the top of a tall tree.

Behavior
Eggs
4, sometimes 3-5, rarely 2-6. Pale blue to bluish white, finely dotted with reddish brown. Incubation is by both parents, about 11-14 days.
Young
Both parents feed nestlings. Young leave nest about 9-13 days after hatching. 2 broods per year, perhaps sometimes 3.
Feeding Behavior
Does much foraging on the ground, using its bill to flip dead leaves aside or dig in the soil as it rummages for insects. Perches in shrubs and trees to eat berries. Will crack open acorns by pounding them with its bill.
Diet
Varied, includes insects, berries, nuts. More than half of diet is insects, including beetles, caterpillars, true bugs, grasshoppers, cicadas, and many others; also eats spiders, sowbugs, earthworms, snails, crayfish, and sometimes lizards and frogs. Berries and small fruits also very important in diet, especially in fall and winter, and eats many nuts and seeds, particularly acorns.
Nesting
Male defends territory by singing loudly from prominent perches. In courtship, male approaches female, singing softly; either bird may pick up leaves or sticks, and present them to the other bird. Nest: Usually placed 2-7' above the ground in a dense shrub, vine tangle, or low tree. Sometimes on the ground under dense cover, or as high as 12' up. Nest (built by both sexes) is a bulky structure, with foundation of sticks supporting a loose cup of twigs, leaves, weeds, grass, bark fibers, lined with finer materials such as grass or rootlets.
