Feeding Behavior
Forages by searching for insects among the foliage, often hovering briefly to pick insects from the undersides of leaves.
Eggs
Usually 3, sometimes 2. White, with specks of brown. Incubation is by female alone, 13-14 days. Young: Both parents feed the nestlings. Young leave the nest 12-14 days after hatching, but can fly only poorly at this stage.

Diet
Mostly insects and spiders, some berries. Feeds on a wide variety of insects, including tree crickets and various smooth caterpillars, also many others. Also eats many spiders. Diet includes berries and small fruits, including those of mistletoe, and some seeds, including those of the tropical shrub Clusia.
Nesting
Details of the breeding behavior have not been well studied. Males sing persistently in spring and summer to defend the nesting territory. Nest: Placed 5-40' above the ground in branch of tree or shrub. Nest (built by female alone) is a neatly built open cup, with its rim woven onto a horizontal forked twig. Nest is made of grass blades, plant fibers, cobwebs, strips of papery bark, the outside often heavily decorated with spiderwebs; lined with fine plant fibers.

Migration
Strictly a summer resident in Mexico and Central America, arriving late in spring. A few from western Mexico apparently go the wrong direction in fall, as there are several fall records along the California coast.
