Long-tailed Tits (Aegithalidae)

Black-throated Tit (Aegithalos concinnus) - HBW 13, p. 96

French: Mésange à tête rousse German: Schwarzkehl-Schwanzmeise Spanish: Mito Gorjinegro
Other common names: Red-headed (Long-tailed) Tit, Black-throated Bushtit

Taxonomy: Psaltria concinna Gould, 1855, Chusan, Zhejiang, eastern China.
Marked geographical variation, and very preliminary genetic studies suggest that this species may, in fact, represent an unresolved species swarm. Races divided into three groups, iredalei forming one group, annamensis another, and remaining four races forming “nominate group”. Race annamensis is morphologically distinct, and its separation as a full species could well be justified on this basis alone. Some SE Asian populations of this species of uncertain racial affinity: thus, birds in NW Thailand presumed to belong with pulchellus, those in EC Laos (.. View all taxonomy...

Taxonomy: Psaltria concinna Gould, 1855, Chusan, Zhejiang, eastern China.
Marked geographical variation, and very preliminary genetic studies suggest that this species may, in fact, represent an unresolved species swarm. Races divided into three groups, iredalei forming one group, annamensis another, and remaining four races forming “nominate group”. Race annamensis is morphologically distinct, and its separation as a full species could well be justified on this basis alone. Some SE Asian populations of this species of uncertain racial affinity: thus, birds in NW Thailand presumed to belong with pulchellus, those in EC Laos (Nakay-Nam Theun) tentatively included with talifuensis, and those in NE Vietnam and on Hainan I presumed to be of nominate race. Race talifuensis perhaps better synonymized with nominate. Proposed race taiwanensis (Taiheisan, in Taiwan) inseparable from nominate. Six subspecies recognized.

Subspecies and Distribution:

  • iredalei (Stuart Baker, 1920) - N Pakistan (Swat) E in Himalayas to NE India (Mishmi Hills, in E Arunachal Pradesh), also SW China (Sun Kosi valley and Tsangpo bend area of S Xizang).
  • manipurensis (Hume, 1888) - NE India (from SE Arunachal Pradesh S to Lushai Hills of E Mizoram) and W Myanmar (Chin Hills).
  • talifuensis (Rippon, 1903) - NE Myanmar (E of R Irrawaddy), S China (C & SW Sichuan S from Emei Shan, S to Yunnan and SW Guizhou), N & EC Laos and NW Vietnam.
