Usually solitary but occasionally travel in pairs. They use a "bark" to communicate with each other, especially during courtship and when alarmed. When feeding they carry their tail high, while moving or standing still it "flops" showing the white underside with every bounce. Antorbital glands are used for marking territory. Grooming is seem in captivity between females, rarely between males. Mating occurs in late fall and early winter, with 1-2 fawns being born in late spring and early summer.
