Distribution

Taxonomy

There are two recognized groups of subspecies: the Pacific group has 8 subspecies and the Interior group has 5 subspecies.[1] Recent DNA evidence may lead to a split of these groups into separate species.[2].

Habitat

Deciduous and mixed forests, primarily oak woodlands.

Behaviour

  • Diet: Gleaner of insects.
  • Breeding: Builds a hanging cup nest suspended from a fork of a tree. The female lays 3-4 eggs. The eggs are mostly white in color, with scattered brown spotting.
  • Migration: Some short-distance and altitudinal migration, but mostly resident. They may join with other species in flocks in winter.
