I love the colouring of this bird. They are found in much Europe, across Asia to Siberia and also in northwest Africa. They grow to about 14.5 cm in length and are part of the finch family.
Chaffinch measures 3.5 x 2.5 inches and is painted on 300gsm smooth Arches watercolour paper.
Many thanks to Kev Chapman for the reference photo.
