Behavior
Finlayson's Squirrel, often called the Variable Squirrel, is a highly active and arboreal rodent known for its incredible agility. Unlike some ground-dwelling squirrels, this species spends the vast majority of its time in the canopy, leaping between branches with remarkable precision. They are strictly diurnal, meaning they are active during the day, with peak activity occurring shortly after sunrise and again in the late afternoon before dusk.
In urban environments like Bangkok or Ho Chi Minh City, these squirrels have become remarkably bold and habituated to human presence. They are frequently seen traversing power lines or raiding garden bird feeders. While generally solitary when foraging, they are not overly territorial and can often be seen in high densities where food is abundant, communicating with a series of sharp chirps and tail flicks when sensing a predator or a rival.

Camera Tips
Because Finlayson's Squirrels are primarily arboreal, the biggest mistake people make is placing their camera too low. For the best results, mount your camera at least 5 to 8 feet up a tree trunk. Angle the camera slightly downward toward a sturdy, horizontal branch or a platform where you can place attractants. Using a strap-on tree mount or a flexible tripod will allow you to get the lens right where the action is.
To lure these colorful acrobats into view, use high-energy treats. Slices of banana, papaya, or even a smear of peanut butter on a branch work wonders. In suburban settings, a standard bird feeder filled with sunflower seeds will almost certainly attract them, but be prepared for them to dominate the scene! If you want to capture their natural climbing behavior, place the bait in a way that forces them to stretch or hang, which makes for dynamic, professional-looking footage.
Set your camera to a fast shutter speed or high-frame-rate video mode. These squirrels move in quick, jerky bursts, and a slow shutter will result in a blurry tail and nothing else. Since they are most active in the early morning, ensure your camera has a wide aperture or decent low-light sensors to capture those first golden hours of activity without excessive grain. In tropical regions, check your lens for fogging during the humid morning hours; a small rain hood or shield can help keep the glass clear for that perfect shot.
