The California thrasher (Toxostoma redivivum) is a large member of family Mimidae found primarily in chaparral habitat in California in the United States and Baja California in Mexico. It is the only species of the genus Toxostoma throughout most of its range.
The California thrasher is closely related to the crissal thrasher (Toxostoma crissale) and LeConte's thrasher (T. lecontei), and the three may form a superspecies. The phylogeography of the California thrasher has been explored through a study analyzing mitochondrial-DNA variation. The distribution of genealogical lineages within the species reflects a complex series of ecological and historical events that have shaped its current geographical distribution. The phylogeographic analysis sheds light on the evolutionary history and the distribution patterns of this bird across its range.
The California thrasher is about 32 cm (13 in) long and weighs up to 90 g (3.2 oz); it is the largest thrasher. It has a distinctive long, decurved beak and a long tail. It is generally deep grayish brown above with olive tones... Wikipedia →

Rare
Under 5% of wildlife watchers report a California Thrasher sighting in San Francisco on a given day, based on 1,076 verified sightings from GBIF citizen-science data. It is the 190th most-seen of the 375 birds we can rate there. Over three days the chance rises to under 5%, and over a week to about 10%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a California Thrasher in San Francisco on a given day, so our monthly data shows no clear season.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most California Thrasher sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
3rd of 4
Of the 4 cities where we can rate California Thrasher sightings, San Francisco ranks 3rd at under 5%. The best odds are in San Diego (United States, about 10%) and Los Angeles (United States, about 10%).
GBIF citizen-science records
It is estimated from how often the California Thrasher is recorded against all the birds logged in San Francisco (1,076 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
