The female lays 3-5 bluish-white eggs with olive spots, which she incubates alone for 12-13 days. The chicks are fed by both parents and fledge 9-10 days after hatching.

This species has a large breeding range and a global population estimated at 2 million individuals. The population in the northern part of its range have undergone a small decline over the last 4 decades, but these represent less than half of the global population. Overall this species is not considered threatened at present.
