Finlayson's squirrel or the variable squirrel (Callosciurus finlaysonii) is a species of rodent in the family Sciuridae. It is found in Cambodia, Laos, Myanmar, Thailand, and Vietnam. It has numerous subspecies that vary greatly in appearance and it occurs in a wide range of wooded habitats, including gardens and parks in cities like Bangkok. It was named in honour of the Scottish naturalist and traveller George Finlayson.
The Finlayson's squirrel has a head-and-body length of about 21–22 cm (8.3–8.7 in) and its tail is about 22–24 cm (8.7–9.4 in) long. There are currently 16 recognised subspecies. Additional subspecies are sometimes recognised. The subspecific name of C. f. boonsongi commemorates Thai zoologist and conservationist Boonsong Lekagul.
The pelage colour in this species is extremely variable and the subspecies are often defined by this feature. Wikipedia →

Likely
About 50% of wildlife watchers report a Finlayson's Squirrel sighting in Khao Yai National Park on a given day, based on 104 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 8th most-seen of the 24 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.
May, July and December–February
In those months about 50% of wildlife watchers report a Finlayson's Squirrel in Khao Yai National Park on a given day, against about 20% in June, the lowest month.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Finlayson's 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 Khao Yai National Park, in our data
Khao Yai National Park is the only park on Wallace's Line with enough records to rate Finlayson's Squirrel sightings: about 50% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Finlayson's Squirrel is recorded against all the mammals logged in Khao Yai National Park (104 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.
