Dupont's Lark Chersophilus duponti

The same size as Eurasian Skylark, with a longer and more slender down-curved bill and small head. Cryptically-plumaged upperparts with pale feather edges, a heavily streaked breast, and a white belly. North African race paler still than Iberian birds. Found in natural steppes and semi-deserts, walking with its head up, looking tall. Fiendishly hard to see. Prefers to run when disturbed rather than fly. Melancholic song delivered high in the sky at dusk and dawn.
