Old World Warblers (Sylviidae)

Russet Bush-warbler (Bradypterus mandelli) - HBW 11, p. 607

French: Bouscarle de Mandell German: Mandellbuschsänger Spanish: Zarzalero de Mandell
Other common names: Common Mountain Warbler

Taxonomy: Dumeticola mandelli W. E. Brooks, 1875, Sikkim, north India.
Part of a species complex that also includes B. luteoventris, B. alishanensis, B. seebohmi, B. montis and B. timorensis; some or all of these often treated as conspecific. Despite having been originally described from Sikkim, presence in India was for long overlooked, presumably owing to its superficial similarity to B. luteoventris; references in older literature to "brown" bush-warblers building two types of nest (open cup and domed) indicate possible differences in nest construction between the two species.

Taxonomy: Dumeticola mandelli W. E. Brooks, 1875, Sikkim, north India.
Part of a species complex that also includes B. luteoventris, B. alishanensis, B. seebohmi, B. montis and B. timorensis; some or all of these often treated as conspecific. Despite having been originally described from Sikkim, presence in India was for long overlooked, presumably owing to its superficial similarity to B. luteoventris; references in older literature to "brown" bush-warblers building two types of nest (open cup and domed) indicate possible differences in nest construction between the two species. Specimens from Thailand and Myanmar with some similarities to race idoneus are considered to be variants of nominate. Birds in C China (Sichuan) seem to be vocally somewhat different from other populations, and may represent an as yet undescribed taxon. Three subspecies recognized.

Subspecies and Distribution:

  • mandelli (W. E. Brooks, 1875) - NE India (E from Sikkim, Darjeeling and Assam), Bhutan, W & N Myanmar, S & C China (N to Sichuan), N Thailand, N Laos and N Vietnam (Tonkin).
  • idoneus (Riley, 1940) - Langbian Plateau, in SC Vietnam (Annam).
  • melanorhynchus (Rickett, 1898) - breeds E China (Hubei S to Fujian); non-breeding to SE China (including Hong Kong).
