Bornean Peacock-pheasant (Polyplectron schleiermacheri)


French: Éperonnier de Bornéo German: Borneopfaufasan Spanish: Espolonero de Borneo

Polyplectron schleiermacheri


, 1877,

south-eastern Borneo


Has been considered a race of P. malacense, but a phylogenetic analysis of male morphology indicates that it is better treated as a full species#R#R; in our own analysis, male differs in its stronger, clearer-cut white chin and throat, with white line running down mid-breast (3); glossy bluish-tinged dark green sides of breast vs dull vermiculated grey-brown (3); blacker belly (2); tan-and-black vs whitish-and-black vermiculations above, thus looking yellower and darker (ns[1+]); ocelli smaller and bluer (both species reflecting purple at some angles, but malacense changing to dark green, schleiermacheri to dark bluish) (ns[2]); much shorter-tailed (on very small sample of 3 vs 5 males, former mean 210, latter 258) (score at least 2); moreover, voice evidently very distinctive#R (3). Monotypic.


Borneo. Exact distribution uncertain#R#R#R.
