(I'm assuming the picture shows a white/albino squirrel)
The Albino squirrel would stick out like a sore thumb in the east because the trees there are usually a very dark brown.
Albinos often have poor eyesight, which puts them at a disadvantage when hunting for food and avoiding danger. In some cases. they have trouble finding a mate, and their inability to camouflage themselves makes them vulnerable to predators.
