Larks eat almost any sort of insect, including venomous spiders, snails, beetles, stink bugs, millipedes, and (rarely) winged bugs taken during flight, as well as seeds, buds, fruits, and green vegetation. All nestlings receive insects to eat. Most larks swallow whole seeds, which are then pulverized by grit in the birds' stomachs. Others use their strong, thick beaks to dehusk seeds or smash them on the ground. Some larks have been observed breaking snail shells on rocks or dropping them from the air. Since water is often unavailable in their environments, many lark species drink dew off leaves or grass, even drinking salty or brackish water when necessary.
