A comprehensive study of the Alaudidae has resulted in a radical reshuffling of genera and several potential splits and lumps being revealed.
The long-mooted split between the North African Long-billed and Crested Larks is further supported pending more information, with a similar potential split in Thekla Lark between North African and Horn of Africa forms. Shore Lark appears to be deserving of splitting into several distinct species, but not enough specimens have been assessed in the paper to reach a conclusion as to which; however, at least one of the Central Asian subspecies seems to be closely related to the American clade.
