Distribution

Thekla's lark is native and resident in France, Spain, Portugal, Algeria, Egypt, Eritrea, Ethiopia, Kenya, Libya, Morocco, Somalia, Tunisia and Western Sahara. Its typical habitat is rugged areas with scrub, bare patches of ground and semi-arid grassland.

Behavior

It nests on the ground, laying two to six eggs. Its food is weed, seeds and insects, the latter especially in the breeding season.

The song is melodious and varied, with mournful whistles and mimicry included. It is softer and more tuneful than that of the crested lark, and may be sung during flight or from the ground or an exposed perch.
