The golden bamboo lemur feeds on young shoots, creepers and leaf bases of the endemic giant bamboo (Cephalostachium viguieri) (4), and has evolved to be resistant to the high concentrations of cyanide found within the tissues of this plant (3). Around 500 g of bamboo are eaten every day; this represents roughly 12 times the usual mammalian lethal dose of cyanide (4). Main peaks of activity occur at dusk and dawn, but it is probably also active at some points during the night (4). It lives in family groups of between 2 to 6 individuals (5). Females give birth in November and December (3).
