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 →

No species of the same family or order lives in Redwood National Park, so these are its closest relatives here: other mammals.
Possible
About 30% of wildlife watchers report a Brush Rabbit sighting in Redwood National Park on a given day, based on 71 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 8th most-seen of the 23 mammals we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.
June and September
In those months about 40% of wildlife watchers report a Brush Rabbit in Redwood National Park on a given day, against under 5% in February and November–December, the lowest months. Those are among Redwood National Park's driest months, with about 50 mm of rain a month against 360 mm in January.
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.
Only Redwood National Park, in our data
Redwood National Park is the only park on Wallace's Line with enough records to rate Brush Rabbit sightings: about 30% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Brush Rabbit is recorded against all the mammals logged in Redwood National Park (71 verified sightings from 2019 to 2026), 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.
