European Greenfinch
Chloris chloris
The European greenfinch is 15 cm (5.9 in) long with a wingspan of 24.5 to 27.5 cm (9.6 to 10.8 in). It is similar in size and shape to a house sparrow, but is mainly green, with yellow in the wings and tail. The female and young birds are duller and have brown tones on the back. The bill is thick and conical. The song contains a lot of trilling and twittering interspersed with wheezes, and the male performs a "butterfly" display flight. Male greenfinches exhibit higher degrees of fluctuating asymmetry. Their bones are more susceptible to disruption during development than those of females.
