The Finlayson's squirrel, a fairly aggressive, non-native species believed to have originated from escaped or abandoned pets, is in danger of 'running amok' following preparations to transform its current habitat the Bidadari area, into a housing development.
Nature enthusiasts worry that the squirrel might escape to other parts of Singapore and displace native species such as the slender and plantain squirrels. Finlayson's squirrels are also known to prey on small native animals like chicks and damage tree bark.
