Crested Lark (Galerida cristata)
Crested and Thekla Larks are extremely difficult to identify. There is a large degree of variation in plumage between individuals creating a high degree of overlap in their identification features. However, the individuals shown above can be identified on the basis of their bill shape: Thekla has a relatively short bill with a convex lower mandible, giving it an overall 'cuter' facial expression; whereas Crested Larks have a longer bill with a straight edge to their lower mandible.
