On the lower east side of Manhattan...I can’t remember the exact street off Second Avenue...there is a postage stamp [one tree] little bit of green and there are black squirrels inhibiting the exclusive spot. :)
Urban dwellers.
This may be them...

Stuyvesant Sq. Park. I grew up down the block on 17th. Only squirrels I ever knew were black. Any open space in that part of Manhattan like Stuyvesant Town, Tompkins Sq Park were home to black squirrels. We sometimes called them Skrats.
