A number of species are doing well, despite, and in some cases because of the increased urbanization of the commonwealth. Peregrine falcons utilize office towers in larger cities as nesting areas, and the population of coyotes, whose diet may include garbage and roadkill, has been increasing in recent decades. White-tailed deer, raccoons, wild turkeys and eastern gray squirrels are also found throughout Massachusetts. In more rural areas in the western part of the state, larger mammals such as moose and black bears have returned, largely due to reforestation following the regional decline in agriculture.
