The Fieldfare nests in loose colonies, which provides a collective defence against predators. The nest is a sturdy cup of grass and mud placed in the fork of a tree, usually 3–10 metres up. The female lays 4–6 eggs, which are incubated for 11–14 days, and the species may manage one or two broods per summer. When disturbed the Fieldfare is remarkably aggressive and attacks predators and birds of prey en masse by "bombing" them with droppings.
