Skylark Bird is the commonest lark in American region. It is rather robust, with a stubby half-crest, rather broad wings with a whitish trailing edge, white outer tail feathers and a distinctively hesitant and fluttering flight action, with much hovering and dithering in the air. The plumage is unspectacular, with the upperparts streaked blackish on buffy-brown, the crown finely streaked black, and the face pale with a whitish supercilium, lores and eyering. The underparts are whitish, with clear blackish streaking on the upper breast forming an obvious breast band.
Skylark Bird is a bird of open country, farmland and steppe, frequently found in cultivated fields. Skylark Bird favours grasslands, coastal meadows, dunes, pastures, heaths, heather moors and grassy hilltops. It requires some open flat areas, and can be found in low stature crops and herbage, as well as in taller crops so long as open ground is available nearby. Western European birds are generally resident, their numbers supplemented in winter by migrant birds from further north and east, which can form large flocks. Migrating birds are easily located by call as they pass overhead.
The song of Skylark Bird is a familiar sound, a melodious collection of sweet chirruping and whistling phrases with a hypnotic cyclical quality. Typically it is sung without breaks for 1 -5 minutes, occasionally for longer, and usually commencing from take-off as the bird ascends into its song flight, which takes it high into the sky. It sings freely from the ground also, although with a less exuberant version. The song sometimes includes mimicry of other species. The calls are frequently heard, and include a variable but bright-sounding dry rolling chirrup, such as "prrr'id", "churrrrip", "prrr'i'i'ew", "pruurt", "pree'eep" and "rreep'chechew", often sounding rather slurred.
