Genus Alauda
Skylark - The Skylark is 16 to 18 cm long. It is a bird of open farmland and heath, known throughout its range for the song of the male, which is delivered in hovering flight from heights of 50 to 100 m, when the singing bird may appear as just a dot in the sky from the ground. The song generally lasts 2 to 3 minutes, but it tends to last longer later in the season. The male has broader wings than the female. This adaptation for more efficient hovering flight may have evolved because of female Skylarks' preference for males that sing and hover for longer periods and so demonstrate that they are likely to have good overall fitness.
Small Skylark - These skylarks frequently rocket up into the sky, fluttering and singing before descending down to earth. Male Oriental Skylarks may also hover in the air and sing, in order to attract a mate.
Japanese Skylark - The Japanese Skylark is a species of lark in the Alaudidae family. It is endemic to Japan.
Raso Lark - The Raso Lark is restricted to one small island in the Cape Verde group, although historically it is believed to have ranged over two other islands, Branco and Sao Vicente Island; all three of these islands were joined in the last Ice Age. Branco island itself has no permanent water and has never been inhabited by people, a fact that has probably saved the lark from extinction until now.
