Bangs's mountain squirrel is a tree squirrel reported from the highlands of Costa Rica and Panama. A study in Costa Rica observed it feeding on flowers, sap, and bromeliads.
The species account describes a narrow, pointed snout and slightly protruding incisors.
During dry-season observations at Volcán Poás National Park in 1984, it ate flower contents, sap, and bromeliad leaves and buds.
An extinction-risk assessment has not been added yet.
