The skylark nests between April and August, and successful pairs may raise up to four broods in one breeding season. Three to five eggs are laid, incubated by the female for 11 days. The nest is always on the ground, and is usually very well concealed within vegetation. The young birds leave the nest when 8 - 10 days old, but remain dependant on their parents for a further 1 - 2 weeks. The male performs his song flights throughout the breeding season. In winter, skylarks move away from upland areas, but large flocks occur on lowland farmland, often in conjunction with other species such as meadow pipits. Stubble fields provide the most important winter food source but set-aside can be useful, particularly if cereal stubbles are in short supply.
