family ALAUDIDAE

In this family the hinder part of the tarsi is transversely scutellated, a character which separates it from all the other Passerine families. The bill has the edges of both mandibles smooth with a notch in the upper. The wing has either nine or ten primaries, the tail has twelve feathers; the plumage of the nestling is spotted below and barred above; the sexes are alike or nearly so; the head is usually crested and the hind claw generally long and rather straight; there is but one full moult, which takes place in the Autumn.

In their general superficial appearance the Larks are very like the birds of the genus Anthus in the preceding family, the Motacillidae.
