BiologyWith fruit forming an important component of the diet, Bulwer's pheasant is thought to be nomadic, moving around according to the fruiting cycle of different trees, and even forming a curious association with wild pigs, in which groups follow the pigs to areas where fallen fruit is abundant (7). As the pigs root around the forest floor for food, they also unearth tubers and bulbs, as well as grubs, and the birds eat what is discarded (8). Insects appear to play an important role in the diet, particularly ants, but also termites and small crickets, as do worms and crayfish, as well as a variety of seeds (4) (7). Observations of males and females with their young suggest that this pheasant may be monogamous. The breeding season appears to be long, and perhaps rather changeable, possibly being stimulated in part by fruiting events, and therefore at different periods from year to year (7). During courtship, males strut slowly about, inflating their blue facial wattles and raising and spreading their impressive tail (2) (6). Clutch size is between two and five eggs, which are incubated for 24 to 25 days in captivity (4). It appears to take at least three years for these pheasants to reach maturity (7).
