Captive breeding challenges posed by Malaysian and Bornean Peacock-pheasants (Polyplectron malacense and P. schleiermacheri).

We describe unique reproductive features of two threatened Galliformes species, the Malaysian peacock-pheasant (Polyplectron malacense) and Bornean peacock-pheasant (P. schleiermacheri). These features pose challenges to successful captive breeding to build up sustainable populations for conservation purposes.
