Did you know?
That the introduction of the Grey squirrel in Europe has a detrimental effect on the native Red Squirrel? By out-competing and the transfer of a virus (parapox virus) Grey squirrel can be responsible for the extinction of the Red squirrels. And its habit of removing tree bark is extremely damaging to trees.

Why do zoos keep this animal

Tree squirrels are among the species which readily choose the zoo as their habitat and become habituated to humans. In their North American range, there is, therefore, hardly a need for keeping grey squirrels in cages, and as a matter of fact almost none are reproted to ISIS.


In parts of Europe, the presentation of grey squirrles may be of educational interest as an example of a highly invasive sopecies.
