The bar-tailed lark is most commonly encountered foraging on the ground, usually in small flocks when outside the breeding season, taking food from the surface and sometimes digging for invertebrate prey. This species mainly feeds on seeds and insects such as grasshoppers (2). In order to survive in the harsh desert environment, the bar-tailed lark is forced to seek shade during the hottest part of the day, sometimes using burrows of the large herbivorous lizard Uromastyx aegypticus for shelter (4). Although the bar-tailed lark is not migratory, individuals may disperse in search of less arid areas, especially during droughts (2).
The bar-tailed lark’s breeding season is determined by rainfall, with egg-laying generally occurring between January and April in north Africa, from September to June in the Cape Verde Islands, and mostly between mid-March and mid-April in the Middle East. The male attracts a mate by singing while flying in an undulating, roughly circular path, before making a steep descent to the ground. After establishing a breeding pair, the female constructs a nest which comprises a shallow depression in the ground beneath a rock or beside a stone, bordered by pebbles and lined with vegetation. A clutch of two to fours eggs is laid, which is incubated for around 12 to 14 days, after which time the chicks are brooded and fed insects by both parent birds. The chicks leave the nest after around 11 days and complete fledging roughly two to four days later (2).
