[5] They were long placed at or near the beginning of the songbirds or oscines (now often called Passeri), just after the suboscines and before the swallows, for example in the American Ornithologists' Union's first check-list.
However, many other classifications follow the Sibley-Ahlquist taxonomy in placing the larks in a large oscine subgroup Passerida (which excludes crows, shrikes and their allies, vireos, and many groups characteristic of Australia and southeastern Asia).
At a finer level of detail, some now place the larks at the beginning of a superfamily Sylvioidea with the swallows, various "Old World warbler" and "babbler" groups, and others.
[8][9] Molecular phylogenetic studies have shown that within the Sylvioidea the larks form a sister clade to the family Panuridae which contains a single species, the bearded reedling (Panurus biarmicus).
[11][12] The genus level cladogram shown below is based on a molecular phylogenetic study of the larks by Per Alström and collaborators published in 2023.
[13] For two species the results conflict with the taxonomy published online in July 2023 by Frank Gill, Pamela Rasmussen and David Donsker on behalf of the International Ornithological Committee (IOC): the rusty bush lark (Mirafra rufa) and Gillett's lark (Mirafra gilletti) were found to be embedded in the genus Calendulauda.
Larks, or the family Alaudidae, are small- to medium-sized birds, 12 to 24 cm (4.7 to 9.4 in) in length and 15 to 75 g (0.5 to 2.6 oz) in mass.
[15] Like many ground birds, most lark species have long hind claws, which are thought to provide stability while standing.
However, in larks the tarsus (the lowest leg bone, connected to the toes) has only one set of scales on the rear surface, which is rounded.
[14] Larks, commonly consumed with bones intact, have historically been considered wholesome, delicate, and light game.
In modern times, shrinking habitats made lark meat rare and hard to come by, though it can still be found in restaurants in Italy and elsewhere in southern Europe.
[24] English composer Ralph Vaughan Williams wrote a musical setting of George Meredith's poem, completed in 1914.
Soon afterwards the composer arranged it for violin and orchestra, in which version it was first performed in June 1921, and this is how the work remains best-known today.
