The animals are active most of the day, spend very little
time on the ground, and forage most of the time. They feed
predominantly on vegetable matter, including fruits, seeds,
buds, and fl owers in season; buds in the winter; and sap and
bark in the autumn, winter, and spring. Hard nuts provided
by visitors were cached in nests or in the trees, but never on
the ground. To a small extent, these squirrels feed on in-
sects, mostly ants.general references: Bertolino 2009; Bertolino, Mazzo-
