Biology

Diet

The diet consists mostly of insects and spiders and occasionally seeds, fruits, and tree sap . This kinglet forages by moving among the tree branches and leaves, moving its wings to flush prey . It also picks insects off of branches, leaves, and needles of the trees.

Reproduction

This species does not breed in the Southeast, but the breeding season begins in late May and extends to mid-July. Nesting usually occurs in conifer or mixed-conifer forest . The nest is usually 4.5-9 m (15-30 feet) high in a conifer. The female builds the nest out of moss, lichen, leaves, and spider webs. The nest is suspended under a branch , usually near the branch's outer edge . The female lays 5-11 (usually 7-9) eggs that she incubates for approximately 12 days. The young are altricial and fledge about 12 days after hatching . Both the male and female tend to the young while they are in the nest and for a period after fledging.
