Brehm, 1831). See Hartert (1907a: 405).    Holotype(lost): “ad. 3” [= juv.], collected by Gustav Radde ( 1831–1903) on 22 April 1886(NS) at “Astara” [= Astara, Azerbaijan; 38.46°N, 48.88°E]. See Radde (1887: 477).   Remarks. Pražák (1897e: 288)based this form on a specimen erroneously described by Radde (1887: 477– 478)as an adult male, although the plumage agrees with that of a juvenile bird (see also Hartert 1907a: 405). The specimen was in the Radde Collection, but its current whereabouts is unknown.
