V. Bianki compiled an avifauna of Mongolian and Tibetan species from P.K. Kozlov’s collections and field diary notes, which he had used on his expedition to these countries in 1899-1901.

Cypselus apus pekinensis Swinh.

Two females adult collected on 3rd June1901, in the Khatu canyon, on the north-west slopes of the Burkhan-Budda mountain range, in the basin of the Yellow River. This subspecies is somewhat different from C. apus with a paler upper side, the paleness appearing mainly on the tail and especially on the head.

Kozlov's diary does not hold any information on this subspecies.
