Feeding Behavior

Forages by moving about actively in shrubs and low trees, searching for insects. Often feeds more among leaves during summer and fall, more on bare twigs and branches during winter and early spring. Sometimes hovers to pick items from foliage. Unlike Blue-gray Gnatcatcher, rarely flies out to catch insects in mid-air.

Eggs

4, sometimes 3-5. Bluish white, very lightly dotted with reddish brown. Incubation is by both parents, about 14 days. Young: Both parents feed the nestlings. Young are reported to leave the nest about 10-15 days after hatching.

Young

Both parents feed the nestlings. Young are reported to leave the nest about 10-15 days after hatching.

Diet

Mostly insects. Feeds on a wide variety of small insects, including beetles, true bugs, caterpillars, wasps, ants, flies, moths, small grasshoppers, and many others; also some spiders. Eats small berries at times.

Nesting

Pairs may remain together all year, defending permanent territories. Cowbirds often lay eggs in nests of this species, and some gnatcatcher pairs wind up raising only young cowbirds. Nest site is in a low shrub, usually in a vertical fork less than 5' above the ground. Nest (built by both sexes) is a compact open cup of plant fibers, grass, weeds, strips of bark, spiderwebs, plant down, and other items, lined with softer materials such as fine plant down, feathers, and animal hair.
