Toxostoma redivivum

The California Thrasher (Toxostoma redivivum) is a striking, medium-large passerine renowned for its impressive decurved bill and secretive habits. Measuring 28-32 cm (11-12.6 in) in length with a wingspan of approximately 30-32 cm (11.8-12.6 in) and weighing 60-90 grams (2.1-3.2 oz), it sports a uniform gray-brown plumage, darker above and paler below, with a distinctive rusty wash on its undertail coverts.

Habitat

Exclusively found in dense, arid to semi-arid scrublands, chaparral, and coastal sage scrub, often preferring riparian thickets within these habitats. It inhabits low to moderate elevations, typically below 2,000 meters (6,500 feet).
