2022 splits and lumps

This list is used to show the various splits, lumps, and discoveries, as well as new families, subfamilies, and genera that may crop up.

2022 proposed splits

 * Red Grouse, Lagopus scotiac is a proposed split from Willow Ptarmigan, L. lagopus based on molecular evidence and differences in plumage (Sangster et al. 2022).
 * Tibetan Sand-Plover, C. atrifrons (including pamirensis and schaeferi) is a proposed split from Siberian Sand-Plover, C. mongolus (including stegmanni) based on phenotypic differences and phylogenetic analysis which demonstrates paraphyly of these two taxa relative to Greater Sand-Plover, Charadrius leschenaultii (Livezey 2010; Wei et al. 2022).

2022 proposed lumps

 * Buteo archeri was formerly treated as a distinct species, Archer's Buzzard (Thiollay 1994; Riesing et al. 2003). But it is now generally regarded either as a subspecies or a rufous morph of Augur Buzzard (Clark 1996; Clark 2003; Dickinson & Remsen 2013; HBW/BirdLife).
