Adult male Common Rosefinches Carpodacus erythrinus are typically crimson-red on the head, breast and rump. Very rarely, this red coloration is wholly replaced by yellow. Although yellow variants of the related House Finch Haemorhous mexicanus of North America are well known and widely documented (e.g. Hill 2002, Harrop 2014, and see below), documentation of yellow Common Rosefinches is scarce – for example, a yellow male is illustrated by Cofta (2021) and the variant is mentioned in the text of Shirihai & Svensson (2018), but is not referenced in Cramp & Perrins (1994), Svensson et al. (2022) or Svensson (2023) – and its occurrence remains poorly known.
