Plantain squirrel (Callosciurus notatus) gnawing on bark

posted in: Feeding-vertebrates, Mammals | 0

The following videos show the plantain squirrels feeding by gnawing on tree barks and then chewing away. Are they feeding on ant larvae, ants, insects hiding under the bark or chewing the soft inner bark which may have pieces of phloem? Phloem tissues are found just beneath the bark and transport sugars manufactured in the leaves during the process of photosynthesis.  The sugars are transported from the leaves to the roots so the roots can obtain a supply of sugars for cell respiration.
