European Greenfinch - Yellow-billed Agate

Description:

The Yellow-beaked Agate is a combination of the sex-linked, recessive Agate factor and the autosomal recessive Yellow-beaked factor. It was with a Yellow-beaked Agate male, like the one in the photo, that I won the 2019 C.O.M World Championship in Matosinhos, Portugal, in January 2020.
