Additional information
Currently either considered to be a valid race (Stepanyan 1990), or as a step on the cline from Falco peregrinus calidus to F.p. japonensis (Vaurie 1965).
The range of this taxon was said to extend from "the Lower Lena to Anadyr, common on the Kolyma" (Buturlin 1907a). It was based on a series of skins which included our birds and were all syntypes, but Sudilovskaya (1962) mentions a [lecto] 'type' from the Kolyma delta (ZMM coll. nr. R-5119, male, spring 1905) and a 'cotype' from Abai (at 63°N on the Indigirka R.; ZMM coll. nr. R-6369, female, spring 1905), both also collected by Buturlin.

Measurements
As far as types in the ZMA are concerned, all measurements were taken by C.S. Roselaar, unless otherwise noted, using the methods as described in Svensson (1992) and comparable with the data published in the Handbook of Western Palearctic Birds. All are in mm, and are given to the nearest mm when taken with a ruler and to one-tenth of a mm when measured with calipers.
