Variable Squirrel

Callosciurus finlaysonii

Also known as Finlayson's Squirrel

Variable squirrels are renowned for their extraordinary coat diversity, ranging from snowy white and jet black to vibrant shades of chestnut, olive, and banded agouti across different geographic populations. Highly active during daylight hours, these agile rodents spend most of their lives high in the forest canopy leaping across branches with remarkable precision. In urban areas like Bangkok, they have adapted seamlessly to city parks and gardens, readily exploiting ornamental plantings and flowering trees.

Why interaction risk is low
Capable of delivering a sharp bite if cornered or handled; observe comfortably from a respectful distance.
Why it is dangerous
Possesses sharp, chisel-like incisors adapted for cracking hard nuts that can easily pierce human skin and cause infection.
How to recognize a risky encounter
Look for a slender, bushy-tailed arboreal squirrel with pelage ranging from pure white or black to red or agouti.
What to do
Never attempt to catch, corner, or pick up a grounded or injured squirrel; contact local wildlife rescuers instead.
Responsible observation
  • Viewing Time: Look for active foraging in mid-morning and late afternoon when squirrels actively leap between canopy branches.
  • Urban Parks: Scan flowering or fruiting shade trees in Southeast Asian cities, where acclimated individuals often tolerate quiet observers.
  • Do Not Feed: Avoid offering processed human foods or attempting hand-feeding, which disrupts natural foraging and risks defensive bites.
