Gaur feed by grazing and browsing forest areas. They live on leaves, stems and seeds. In summer, when fresh plant material is not always available, they will also include bark and fruit into their diet. The bark of the teak tree has been reported to contain high concentrations of calcium and phosphorus, so the consumption of teak bark might help the animals to get additional nutrients into their diet. Gaurs live in small groups of 8 to 11 individuals. The oldest female, called matriarch, will lead the group.
