The Baja California rock squirrel (Otospermophilus atricapillus) is a species of rodent in the family Sciuridae. It is endemic to Baja California, Mexico. Otospermophilus atricapillus is considered as the sister species of Otospermophilus beecheyi and both have been considered different species mainly by its colorations. The rock squirrel is a relatively large ground squirrel, with males typically larger than females. Their fur is generally gray with a mottled or variegated pattern, giving them a distinctive appearance. Their tails are long and bushy, often used for balance and communication. Their heads are broad with small, rounded ears and large, expressive eyes.
Rock squirrels are primarily found in the southwestern United States and northern Mexico. They are well-adapted to arid and semi-arid environments, including rocky hillsides and deserts. Common states where you can find rock squirrels include Texas, New Mexico, Arizona, and parts of Colorado and Utah. They often make their homes in crevices, rock piles, and burrows, which provide ample shelter and protection from predators.
This species is poorly known. It is found in desert shrubland and... Wikipedia →

With luck
About 10% of wildlife watchers report an Ardila De Rocas De Baja California sighting in El Vizcaíno Biosphere Reserve on a given day, based on 6 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 15th most-seen of the 16 mammals we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.
January, April, June and September–October
In those months about 20% of wildlife watchers report an Ardila De Rocas De Baja California in El Vizcaíno Biosphere Reserve on a given day, against under 5% in February, May, July–August and November–December, the lowest months.
Between 10 pm and 1 am
Across all the parks we cover, that three-hour window holds the most Ardila De Rocas De Baja California sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is seen both by day and at night.
Only El Vizcaíno Biosphere Reserve, in our data
El Vizcaíno Biosphere Reserve is the only park on Wallace's Line with enough records to rate Ardila De Rocas De Baja California sightings: about 10% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Ardila De Rocas De Baja California is recorded against all the mammals logged in El Vizcaíno Biosphere Reserve (6 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.
