Cuckoo Roller (Leptosomus discolor) - HBW 6, p. 395

French: Courol German: Kurol Spanish: Carraca Curol
Other common names: Courol

Taxonomy: Cuculus discolor Hermann, 1783, Madagascar.
Sometimes considered to belong within Coraciidae, where typically awarded its own separate subfamily. Race gracilis sometimes considered a separate species, on basis of differences in size, plumage and voice; however, intermedius appears intermediate in plumage and may thus link the other two. Proposed race anjouanensis synonymous with intermedius. Three subspecies currently recognized.

Subspecies and Distribution:

  • gracilis Milne-Edwards & Oustalet, 1885 - Grand Comoro (Ngazidja).
  • intermedius Hartert & Neumann, 1924 - Anjouan (Ndzuani).
  • discolor (Hermann, 1783) - Mohéli (Mwali) and Mayotte (Maore), and Madagascar.
