We have predominately grey squirrels in Queens, but we have been seeing black squirrels for the past couple of years. The first black squirrels I ever saw were in Toronto, about 20 years ago.
The only black squirrels I’ve ever seen are the rock squirrels, and only out in the country-the few times I’ve lived in a city, I’ve only seen the gray ones-I live in a remote rural area and there are both gray and black squirrels-the black ones only live on the cliffs over the river-they don’t get grabbed by the hawks as much as the gray squirrels do-probably because they live under the cliffs and tree canopy and are harder for birds of prey to spot and dive down on-hawks like to hunt prey on open ground...
