The clutch is two or three, rarely four, brown-speckled white eggs. They are incubated by the female alone for 12–14 days to hatching.
The roughly globular nest, built by the female, is made of grass and weed stems compacted into a thick mass, and lined with pieces of grass inflorescences and bast fibre. It has a side entrance and is placed usually less than  above the ground, often among grass or weeds on a road or river embankment.
