The Greenfinch is a resident bird. It is a very stocky finch and in winter can be seen in large flocks. In summer they nest in colonies in dense shrubs. The smooth, glossy eggs are white to pale beige with blackish markings, and approximately 21 mm by 15 mm. The female incubates the eggs by herself. After the young hatch, they are fed by both parents.
The male is bright green with a yellow wing bar. The female and juveniles are much drabber with streaking on their breast.
