Red-bellied Squirrel

Sciurus aureogaster

Also known as Mexican Gray Squirrel, Mexican Grey Squirrel

Mexican gray squirrels spend daylight hours leaping through tree canopies, stripping pine cones and acorns while caching surplus nuts in shallow leaf litter. Coat coloration varies dramatically across regions, displaying vibrant reddish underbellies in typical morphs alongside completely black melanistic individuals. Pairs build spherical leafy dreys high in branch crotches to shelter litters from seasonal downpours and raptors.

What to do
Never attempt to hand-feed or corner the animal, and always allow a clear escape route.
Responsible observation
  • Spotting Dreys: Look high in the canopy for spherical leaf-and-twig nests tucked into sturdy branch forks.
  • Listening for Calls: Tune in for sharp, scolding chattering barks uttered from mid-canopy perches.
