The southern Amazon red squirrel (Sciurus spadiceus), is a squirrel species from South America where it inhabits forests in much of north-western South America east of the Andes. Three subspecies are currently recognised. It is a dark red colour, or a dark brown grizzled with ochre, has whitish underparts and grows to a total length of 48 to 63 cm (19 to 25 in), including a very long tail. It spends much of its time on the ground in the undergrowth and feeds largely on nuts. Little is known of its breeding habits, but it is a sociable species, several individuals often feeding together in one tree. This squirrel faces no particular threats, has a wide range and is relatively common, and the International Union for Conservation of Nature lists it as a "least-concern species".
One of the largest species of squirrel in its range, S. spadiceus ranges from 48 to 63 cm (19 to 25 in) in total length, including a very long, 24 to 34 cm (9.4 to 13.4 in), tail. Males and females are similarly sized, and weigh between 570 and 660 g (20 and 23 oz). The fur is typically reddish-brown over most of the body, grizzled with paler yellow, but can be dark brown to near-black, especially... Wikipedia →

Likely
About 40% of wildlife watchers report a Southern Amazon Red Squirrel sighting in Santa Cruz de la Sierra on a given day, based on 26 verified sightings from GBIF citizen-science data. It is the 2nd most-seen of the 5 mammals we can rate there. Over three days the chance rises to about 80%, and over a week to over 90%, if each day is a fresh chance.
October
In that month about 60% of wildlife watchers report a Southern Amazon Red Squirrel in Santa Cruz de la Sierra on a given day, against under 5% in July and August, the lowest months.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Southern Amazon Red Squirrel sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Santa Cruz de la Sierra, in our data
Santa Cruz de la Sierra is the only city on Wallace's Line with enough records to rate Southern Amazon Red Squirrel sightings: about 40% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Southern Amazon Red Squirrel is recorded against all the mammals logged in Santa Cruz de la Sierra (26 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.
