Greenfinches are characterised by a colourful olive-green plumage with flashes of yellow on the wings and tail, males and females are similar - the female's colour is just a bit duller. In spring the male shows off a wavering display flight that can look more like that of a bat or butterfly.
With a short conical and powerful beak they are masters at breaking open large seeds to eat. They like to build a nest of grass and twigs in conifer trees and bushes, while the simple song can actually be quite musical. All in all greenfinches are a most welcome visitor to any garden.
