Wrentit
Wrentit
Chamaea fasciata
At a Glance
In the chaparral, the dense low brush that grows along the Pacific seaboard, Wrentits are often heard and seldom seen. Pairs of these long-tailed little birds move about actively in the depths of the thickets, rarely perching in the open or flying across small clearings. They are remarkably sedentary; a bird may spend its entire adult life in an area of just a couple of acres.

Habitat
Chaparral, brush, parks, garden shrubs. Within its range, the Wrentit inhabits most kinds of dense low growth. Most common in chaparral, thickets of poison oak, and coastal sage scrub; also lives in streamside thickets and in shrubby areas in suburbs and city parks. Extends very locally to edge of desert.

Behavior
Eggs
4, sometimes 3-5. Pale greenish blue, unmarked. Incubation is by both parents, about 16 days. Female reportedly incubates at night, both sexes taking turns during the day.
Young
Both parents feed nestlings. Young leave the nest about 15-16 days after hatching, are tended by parents for another 2-3 weeks.
Feeding Behavior
Forages actively in dense low growth, gleaning insects from twigs, sometimes hanging upside down to examine foliage. Sometimes hovers briefly while taking an item. Will hold a large insect with one foot while breaking off the wings.
Diet
Mostly insects and berries. Feeds heavily on insects, especially in spring and summer, including ants, small wasps, caterpillars, beetles, scale insects, leafhoppers, and others, plus spiders. Eats many berries, especially in fall and winter, including those of poison oak. Will come to bird feeders for bread crumbs or other soft items, and takes sugar-water from hummingbird feeders.
Nesting
May mate for life. Pairs remain together on nesting territory at all seasons. Nest: Well hidden by foliage in a dense low shrub, usually 1-4' above the ground, rarely above 10' in small tree. Firmly lashed into place, attached to clusters of twigs or built in fork of branch. Nest (built by both sexes) is a neatly constructed, compact cup, typically made of strips of bark and spiderwebs, lined with fine plant fibers and sometimes animal hair. Outside of nest may be decorated with bits of lichen.
Climate Vulnerability
Conservation Status
Has declined in some areas with increasing development of coastal regions. Still fairly widespread and common.
