Range DescriptionPolyplectron schleiermacheri is endemic to Borneo, where it is known from Sabah and Sarawak, Malaysia and Kalimantan, Indonesia. A 1996 questionnaire survey of 97 villages across central Kalimantan found that two-thirds of these communities described it as rare or very rare, whilst one-third considered that it was fairly common. Feathers of the species were produced at four locations. Eighty-five percent of individual interviewees felt that it had declined. There are recent reports from Danum Valley, Deramakot Forest Reserve (G. Davison in litt. 2007) and Ulu Tongod (Sabah), Gunung Mulu National Park (Sarawak), Nangatayap (near Gunung Palung National Park, west Kalimantan), Muarakarum/Palangkaraya, central Kalimantan, Sungai Wain, south-eastern Kalimantan and reports from Sukau (Sabah). Records are sporadic (B. van Balen in litt. 2012), hindering a more robust assessment of its status.
