Himalayan Greenfinch (Chloris spinoides) in the ‘Isabelle’ colour morph

Description:

The Isabelle mutation was established in the Himalayan Greenfinch (Chloris spinoides) over 30 years ago through intraspecific hybridisation with the European Greenfinch (Chloris chloris). We owe this breeding work in particular to Patrick Brizard. The Isabelle mutation is sex-linked and recessive.
