Larks are a group of birds that occur naturally in the Old World and in northern and eastern Australia. The only exception is the Horned Lark, which is native to North America.
Most lark species have a mostly streaked brown plumage, with some bold black or white markings, and long hind claws.
These small to medium-sized birds measure from 12 to 24 cm (5 to 8 inches) in length (including the tail) and weigh between 15 to 75 grams (0.5 to 2.6 ounces).
Some lark species have heavy bills that are suitable for cracking seeds open, while others have long, down-curved bills, suitable for digging through litter in their search of insects.
