About Copsychus stricklandii Motley & Dillwyn, 1855
The white-crowned shama (Copsychus stricklandii) measures around 21–28 cm (8.3–11.0 in) in total length, which includes a 7 cm (2.8 in) tail on adult males, and weighs between 31–42 g (1.1–1.5 oz). Its upperparts are mostly blue-black, which contrasts with its orange-rufous underparts. It has a white rump and a black throat. It looks very similar to the C. m. suavis subspecies of the white-rumped shama, which lives in southern and western Borneo in place of the white-crowned shama. The two species hybridize in areas where their ranges overlap. The white-crowned shama differs from this related subspecies by having a white crown instead of a black one. The distinctive Maratua form C. s. barbouri is approximately 20% longer than the nominate form, and has an entirely black tail, rather than white outer tail feathers.
