Skylark - Alauda Arvensis
Skylarks are characteristic of semi-natural grassland systems from sand dunes through heathland to marginal upland, but are most common in arable farmland, making use of the nesting cover and bare ground for feeding that crops themselves provide throughout the year. Males are highly territorial, using long song flights at high altitude to broadcast to rivals and potential mates because the open landscapes they prefer are devoid of high perches. The stamina required to sustain long song flights has led to song flight length being used as an “honest signal” of male quality by females, allowing male Skylarks to advertise themselves without bright plumage, so they have kept the cryptic, brown and streaked coloration that affords them protection from predators on the ground.
Although migratory in much of northern Europe, British breeding Skylarks are believed not to move far between seasons, although upland birds move to lower latitudes. They can then often begin to breed in March and continue into July, making up to three breeding attempts. In winter, they mostly use crop stubble and fallow fields, in which they forage for weed seed and spilled grain, often in large flocks. Throughout the year, the Skylark’s heritage as a steppe species is apparent in its avoidance of vertical structures, which restricts the suitability of farmland with a high density of hedgerows.
