The alternate name should not be confused with the Indonesian red-bellied squirrel (Rubrisciurus rubriventer) or the Asian red-bellied tree squirrel (Callosciurus erythraeus).
Behaviour
editSince the introduction of the species to Florida in the late 1930s, its nesting locations have become more irregular, nesting in varying species of trees and even choosing to nest in hurricane debris.[5][6]
Ecology
editSciurus aureogaster has had an extremely negative impact on Thrinax radiata populations on Elliot Key. It uses palm fibers as nesting materials and consumes the palm itself, often killing the plant.[7]
Subspecies
editThe two subspecies each have many synonyms associated with them:[3]
- The subspecies S. a. aureogaster was also known as S. a. chrysogaster, S. a. ferruginiventris, S. a. hypopyrrhus, S. a. hypoxanthus, S. a. leucogaster, S. a. maurus, S. a. morio, S. a. mustelinus, S. a. raviventer and S. a. rufiventris.
- The subspecies S. a. nigrescens was also known as S. a. affinis, S. a. albipes, S. a. cervicalis, S. a. chiapensis, S. a. cocos, S. a. colimensis, S. a. effugius, S. a. frumentor, S. a. griseoflavus, S. a. hernandezi, S. a. hirtus, S. a. leucops, S. a. littoralis, S. a. nelsoni, S. a. nemoralis, S. a. perigrinator, S. a. poliopus, S. a. quercinus, S. a. rufipes, S. a. senex, S. a. socialis, S. a. tepicanus, S. a. varius and S. a. wagneri.
