Taxonomy

It is closely related to the white-rumped shama (Copsychus malabaricus), and is sometimes considered a subspecies of that species.[2] In turn, the white-crowned shama has two subspecies:[3]

  • C. s. stricklandii Motley & Dillwyn, 1855 – north and north-eastern Borneo, including Banggi Island
  • C. s. barbouri (Bangs & Peters, 1927[4]) (Maratua Shama) – Maratua Islands

The specific name was bestowed in honour of Hugh Edwin Strickland[5]

Description

The white-crowned shama is about 21–28 cm (8.3–11.0 in) in length (including a 7 cm (2.8 in) tail in adult males) and 31–42 g (1.1–1.5 oz) in weight. Mainly blue-black upperparts contrast with orange-rufous underparts. It has a white rump and black throat. It is largely similar in appearance to the white-rumped shama subspecies C. m. suavis, which replaces it in southern and western Borneo, and hybridises with it where the ranges meet.[6] It differs in having a white, rather than black, crown. The distinctive Maratua form C. s. barbouri is about 20% longer than the nominate, and has an all-black tail, rather than white outer rectrices.[1]

Aviculture

White-crowned shamas are bred by local aviculturists in Borneo as cage-birds valued for their singing ability. They continue to be trapped as it is believed that wild-caught young birds are stronger, and better songsters, than those bred in captivity.[1]

gollark: No, I mean the performance could be improved.
gollark: It calls that in a loop.
gollark: Maybe the weighted random implementation is bad?
