Partial-albino Red-billed Chough
Ulaanbaatar-based ornithologist Uugan sent me a photograph of a partial-albino Red-billed Chough which he observed in Tariat sum (a sum is an administrative subdivision below the aimags=provinces in Mongolia, roughly comparable to a County in the USA) in the northern Khangai Mountains on 17 May 2007.
