European goldfinches breed in April-July. They nest in a cup made of moss, grass and lichen, and lined with wool and plant down. The nest is placed on an outer branch of a leafy tree or scrub, often in a garden, orchard or hedgerow. The re the female lays 3-7 pale blue eggs with reddish markings, which she incubates alone for 10-14 days. The chicks are fed by both parents and fledge 13-18 days after hatching. Each pair raises 2-3 broods per season.
