Isabelline (or Red-tailed) Shrike" Lanius isabellinus has been treated in the past as conspecific with Red-backed Shrike L collurio (e.g. Vaurie, 1959) or with both Red-backed and Brown Shrike L cristatus (e.g. Dement’ev and Gladkov, 1954). Until recently, it has generally been treated as a separate species comprising four sub-species: two, phoenicuroides and speculigerus breeding in central Asia and migrating southwest, wintering in Arabia and NE Africa; two, isabellinus and tsaidamensis, breed in North China and are shorter distance migrants, wintering in Pakistan and NW India west to Iran.
