In captivity, Germain’s peacock-pheasant appears to breed almost year-round, with females laying again once their young become independent. In the wild, this bird has been observed breeding from February to April. Clutches usually consists of two eggs, which are incubated for 21 to 22 days (6).
Nothing is known of the diet in the wild, although it is probably similar to that of the grey peacock-pheasant (Polyplectron bicalcaratum), with which this species shares its range (6). This consists of berries, fruits, seeds, wild figs, grubs, ants, insects, snails and other small animals (2).
