An ongoing study of the southern adder that began in 2004 has located 18 specimens to date and revealed some important information on the species’ biology and behaviour (6). Unlike other members of the Bitis cornuta - inornata species complex, the southern adder is partially arboreal, having been recorded climbing up to heights of two metres (5). The adder appears to feed on lizards, but will also take small rodents (7). The study has also shown that individual snakes tend not to travel any great distance, but prefer to stay within a limited area, a behaviour that may prove significant to the snake’s long-term conservation (8).
Bitis species are all believed to be ovoviviparous, giving birth to live young (4).
