Song diagnostic also has distinct 3 syllable call in the ascending. Resident.

Thekla Lark Galerida theklae Cogujada Montesina

thekla-lark1Common, but more localised than Crested Lark, being largely confined to open hillside and mountain terrain with scrub and bushes. Occasionally inhabits the same areas as Crested Lark, so habitat not always determinate for identification purposes. Most common lark species on rocky and scree slopes at higher altitudes, where Skylark also occurs. Generally appears more slender and smaller than Crested Lark and apart from the autumn, when fresh plumage is evident (both juveniles and adults undergo full moults during late summer), the mantle and wings are greyish and pale. Short billed and lacks the curve/hook at the tip of the upper mandible. White supercilium and eye ring, with heavy black streaking to upper and medium breast. Song diagnostic and frequently has 2 syllable call in the descending. Resident.lark_id
