I live in a suburb where there are plenty of trees. And squirrels. I can't go out without seeing at least one. Now lately I have hiked in close by state parks and I didn't see not even one squirrel in forest setting. I wonder, why is that? I assume in the forest with all those trees there is plenty of food and places to hide. So what gives? Is it the lack of natural predators that makes the squirrel population to prefer the urban setting????
