These deer are usually solitary, but occasionally they travel in pairs. They use a "bark" to communicate with each other, especially during courtship and when alarmed. When feeding they carry their tails high, while moving or standing still they "flop" showing the white underside with every bounce. Antorbital glands are used for marking territory. Grooming is apparently very important, and they will groom themselves frequently. All grooming is seen in captivity between females, rarely between males.
