The greenfinch is 15 cm (5.9 in) long with a wing span 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 twitters interspersed with wheezes, and the male has a "butterfly" display flight. This bird is widespread throughout Europe, north Africa and south west Asia. It is mainly resident, but some northernmost populations migrate further south. The greenfinch has also been introduced into both Australia and New Zealand. In Malta, it is considered a prestigious song bird, and it has been trapped for many years. It has been domesticated, and many Maltese people breed them. In Hungary, it is threatened.
