Due to the saola's relatively recent discovery and the remoteness of its range, little information on this elusive species' behaviour has been gathered. Locals have said that the species is generally solitary, although there have been a few reports that the saola sometimes travels in small groups (8). Most of the data on reproduction comes from a single pregnant female from northern Lao. Calculations made from the size of this female's foetus, together with all other data to date, suggest that the saola is a seasonal breeder, mating between late August and mid-November. If this is the case, births would be timed to coincide with the onset of the monsoon, somewhere around April, May and June in northern Lao (2) (8). A single captive individual has provided the source of most behavioural information on this species. The individual was primarily diurnal or crepuscular, with activity often concentrated early in the morning and late in the afternoon (2). The saola browses on the fleshy herb layer of riverside vegetation (8).
