The brush rabbit (Sylvilagus bachmani), or western brush rabbit, or Californian brush rabbit, is a species of cottontail rabbit found in western coastal regions of North America, from the Columbia River in Oregon to the southern tip of the Baja California Peninsula. Its range extends as far east as the eastern sides of the Sierra Nevada and Cascade mountain ranges.
The brush rabbit is a small rabbit with short legs and a short tail. It is dark gray on the sides and back, and pale gray on the belly and the underside of the tail. The whiskers are mostly black, although some have white tips. Adult rabbits measure anywhere from 30.3 to 36.9 cm (11.9 to 14.5 in) in length, and range in weight from 511 to 917 g (1.127 to 2.022 lb).
Large numbers of geographically defined subspecies have been proposed, including in Oregon, ubericolor; in California, cinerascens, mariposae, riparius, tehamae and trowbridgii; and in Baja California, cerrosensis, exiguus, howelli, peninsularis and rosaphagus. Subspecies bachmani, macrorhinus and virgulti are less geographically restricted. Of the various proposed subspecies, only the following are currently recognized, the others... Wikipedia →

With luck
About 10% of wildlife watchers report a Brush Rabbit sighting in San Francisco on a given day, based on 409 verified sightings from GBIF citizen-science data. It is the 12th most-seen of the 38 mammals we can rate there. Over three days the chance rises to about 20%, and over a week to about 50%, if each day is a fresh chance.
Any time of year
In every month with enough records, about 10% of wildlife watchers report a Brush Rabbit 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 Brush Rabbit sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 4 cities where we can rate Brush Rabbit sightings, San Francisco ranks 2nd at about 10%, level with the leaders once rounded. The best odds are in Portland (United States, about 10%).
GBIF citizen-science records
It is estimated from how often the Brush Rabbit is recorded against all the mammals logged in San Francisco (409 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.
