The distinctive breeding season call of the male greenfinch is a repeated, harsh, drawn out call reminiscent of a long-tailed cuckoo but not quite so strident.
According to Heather & Robertson, the greenfinch often nests in loose colonies, sometimes within a few metres of each other. The nest is cup shaped, composed of twigs and moss lined with rootlets and feathers; placed in a shrub or tree, usually at varying heights, and built by the female. The eggs are dull white to greenish–blue, sparingly marked red-brown and pale violet, approximately 21 mm by 15 mm. Incubation is 13–14 days, by the female. After the young hatch, they are fed by both parents.
