A Chapter of the National Audubon www.VenturaAudubonSociety.org
Through ORC’s Wildlife Education Program, Kim and her volunteer staff travel to schools and other organizations to
show how birds of prey are an important element in the chain of life. As all things are interconnected, teaching about
raptors and other wildlife in our community means teaching about environmental and ecological concerns and ex-
plaining what individuals can do to help.
This past year, ORC has taken in 1,350 birds. Kim will give a short presentation on the new Rehabilitation Facility
following the introduction of her live, non-releasable ambassador raptors (hawks, falcons, owls, and maybe a sur-
prise bird!).
BIRD OF THE MONTH – FEBRUARY 2010
Article and Photo by DAVID PEREKSTA
California Thrasher (Toxostoma redivivum)
February is still a good month to seek out wintering birds in Ventura County, but some of our resident species are al-
ready singing and establishing territories. One of the species that starts breeding early is the California Thrasher.
The California Thrasher is a medium-sized, long-tailed songbird. It has dark brown upperparts, buff-brown underparts, a
whitish throat, vague eyebrow, dark mustache, and long, decurved black bill. It is similar looking to Crissal and Le-
Conte’s Thrashers, but neither of those species inhabits Ventura County. The only species that it can be confused with
locally is the California Towhee, which is similarly colored and patterned, but has a shorter, stubby bill. Its song is a se-
ries of deep, rich, slow phrases, like the songs of other mimids. Calls are a chuck and quip.
California Thrashers are common, but difficult to see as they spend most of their time on the ground in dense growth
including chaparral, streamside thickets, coastal sage scrub, and shrubby areas in parks and suburbs. They are often
seen walking or running on the ground with their tail held high. They rake their long, curved bills sideways through leaf
litter and probe in the soil for beetles, ants, wasps, and spiders. Their diet is also composed of seeds and berries taken
from bushes or the ground. Males and females are most easily seen when they are singing from the tops of shrubs or
low trees. Residents of lowlands and foothills, they rarely wander into higher mountains.
The species is nearly endemic to California. Its range is limited to the west slope of the Sierra Nevada, and the Coast
Ranges from just south of the Oregon border to northern Baja California, Mexico. It is a strictly permanent resident and
rarely wanders even a short distance from breeding areas.
In Ventura County, California Thrashers occur nearly everywhere the habitats mentioned above are present. They are
common in the extensive chaparral and coastal sage scrub in the Santa Monica Mountains (e.g., La Jolla and Sycamore
Canyons, Circle X Ranch, and Satwiwa) and Transverse Ranges (e.g., Rose Valley, Cuyama Valley, and Highway 33
above Ojai). They are easiest found in late winter and early spring when they sing from exposed perches and can often
be coaxed into view at other times by “pishing.” The easiest place to find them locally is in the streamside thickets and
chaparral around the campground at Big Sycamore Canyon, but they are also readily found in the hills surrounding Ven-
tura, Ojai, Camarillo, and Thousand Oaks.
