 The female may be offered food by the male during courtship . He has a brief courtship display in which the neck is extended and the head held down , the tail is fanned , and the wings are spread with the tips touching the ground . He will then attempt to approach the female from behind , and then leap on her back to <unk> . The nest is typically in grassland , sometimes in safer sites along a hedge , or near an isolated tree or bush , or in overgrown vegetation . Where grass is not tall enough at the start of the season , the first nest may be constructed in <unk> or marsh vegetation , with the second brood in hay . The second nest may also be at a higher altitude that the first , to take advantage of the later @-@ developing grasses further up a hill . The nest , well hidden in the grass , is built in a scrape or hollow in the ground . It is made of woven coarse dry grass and other plants , and lined with finer grasses . Although nest construction is usually described as undertaken by the female , a recent <unk> study found that in the captive population the male always built the nest .
