Resident in the coastal and foothill areas
of California, the California Thrasher is found from northern
California into areas of northwest Baja California. This large
thrasher is common in dense chaparral but also found in oak
woodlands, sage and pine-juniper scrub and sometimes even
in parks and gardens. Its attractive song is heard year-long.
It breeds from sea level to higher parts of the montane chaparral
community. It comes readily to bird feeders, especially in
The population size is estimated broadly
at around three million pairs, down perhaps 5% through habitat
loss since about 1950. No downward trends are indicated in
undisturbed habitat, but habitat-clearing clearly results
in population decline. It may be impacted by pesticide poisoning.
The species is affected by habitat fragmentation, and has disappeared
from the Monterey Peninsula due to development, maturation
of pine forest and reduction of understory scrub, and heavy
use by tourists.
