Little Bustards are much smaller than their cousins, the Great Bustards and can be much harder to find. In spring males give a characteristic sound (a bit like blowing a raspberry) which is far-carrying and usually uttered from a prominent position, such as a mound of earth or a rock. They will also display by jumping up into the air or chasing another male in a rapid flight. They will usually be found in places where the grass is quite long, so they can hide easily. In winter they form flocks, which can sometimes be as large as several hundred birds. The best time to find them in the winter is early morning or late afternoon when the low sunshine catches their white bellies, because the rest of their plumage is well camouflaged with dry vegetation.
