Accentor erythropygus

Quick answer

Holotype: ZMB 19767 (B. 7841), skin, ♂, collected by B. Dybowski on 15 July 1870 [= 27 July 1870] in “ regii alpini ” and " Utulik " (Dybowski’s label) at Lake Baikal, i. e. apparently in the Hamar-Daban Mountains (cf. Mlíkovský 2007 a: 57) above the village of Utulik at Utulik brook. Type locality: “ in der alpinen Region südlich vom Baikal-See ” (Cabanis 1870 c: 456), i. e. “ in the alpine region south of Lake Baikal ”. Dybowski’s itinerary (Dybowski 1930; Mlíkovský 2007 a) and data on the Dybowski label attached to the specimen further allow restriction of the type locality to the alpine region of Hamar-Daban Mountains at the Utulik brook above Utulik village [51.6 ° N, 104.0 ° W]. Remarks: Cabanis (1870 c) also mentioned a fledgling received from Dybowski (ZMB 19768, B. 7841; not found in 2008), which he was unable to compare with a similarly young Accentor alpinus [= Prunella collaris (Scopoli, 1769)], having none at his disposal. He added, however, that a few " adult " feathers already present on the young differed from the same feathers of A. alpinus, and he (Cabanis 1870 c) only conditionally identified the young as belonging to Accentor erythropygus. It thus does not belong to the type series upon which the species was based.
