There are 4 subspecies:
- L. c. celata:
- L. c. orestera:
- L. c. lutescens
- L. sordida:
- Coastal southern California and islands off south-western California and Baja California
Marshes, suburban gardens, semi-wooded areas, oak savannah, riparian, open grass beside rivers and ponds.
Their diet consists mostly of insects and spiders during the summer months, switching to berries and fruit in the winter. Very active feeders in low shrubs, sometimes hovering.
The female chooses the nest site, which is usually on the ground under dense vegetation, but may be in a shrub, low tree, fern, or vine. The nest is an open cup formed from grasses, shredded bark and moss, lined with fine grass and hair. The clutch consists of 4 to 5 eggs which are incubated for 11 to 13 days. Both parents feed the young.
Song a variable trill, usually dropping in pitch and volume towards end. Usual call a hard, sharp, "tick."
