So-called “gray squirrels” and “black squirrels” are two color morphs of the same species:  Sciurus carolinensis . Until 150 years ago, the black morph  was much more abundant . Yet now the black morph is rare, except in cities.

Why has the black morph declined? Why does it linger in cities? Will it return again to the countryside? The landscape is changing rapidly. Will the gray squirrel, and other mammals like it, be able to adapt quickly enough?

 SquirrelMapper  is investigating these questions along with partner at UWIN.
