Food habits of the Dusky-striped Squirrel Funambulus sublineatus (Mammalia: Rodentia: Sciuridae)
Main Article Content
Abstract
We report the first observations of feeding behaviour of the Dusky-striped Squirrel Funambulus sublineatus in the Western Ghats. It was observed feeding on eight plant species, including four non-native species. Feeding was observed in forests as well as in plantations and agricultural habitats, indicating the urgent need for studies in such human-modified landscapes.
