Diet

Mostly insects. Feeds on a wide variety of insects, including many beetles, caterpillars, true bugs, ants, small wasps, and many others. Also eats many spiders, plus some millipedes and snails. Occasionally may eat tiny fish. Also sometimes eats berries, perhaps mainly in fall and winter.

Nesting

Male sings in spring to defend territory and attract a mate. In courtship, male perches near female, with wings half-opened and fluttering, tail spread and moving from side to side, while he sings or calls. Male may have more than one mate. Nest site is in any kind of natural cavity close to the ground (lower than about 6'), including holes among upturned roots of downed trees, cavities in rotten stumps, old woodpecker holes, crevices among rocks, holes in streambanks, sometimes under porches of cabins. Within cavity, both sexes help build nest of grass, weeds, moss, rootlets, lined with animal hair and feathers. Male may also build several unlined "dummy" nests.
