through the canopy in the early morning or resting on a
branch during the heat of the day. Leaf nests are built on
branches high in the canopy. Primarily herbivorous, S. yu-
catanensis feeds on soft fruits, nuts, seeds, fl owers, buds, and
shoots. A litter of two to three young is produced during the
dry season (April–July). Raptors are probably a major preda-
tor, along with felids, canids, procyonids, primates, and
snakes. Deforestation is the major threat to this species;
however, Yucatan squirrels are hunted, especially in Yuca-
tán and Quintana Roo (México), and exploited populations
may be reduced.
