Eastern Long-billed Lark vs Cape Long-billed Lark

The Eastern Long-billed Lark and Cape Long-billed Lark are similar in appearance, both having a predominantly gray-brown plumage with streaks. The most reliable difference is the bill shape: the Cape Long-billed Lark has a more obviously curved and very long bill compared to the Eastern Long-billed Lark.

Focus on the bill shape: the Cape Long-billed Lark's bill is more obviously curved and longer. This is the most reliable field mark for distinguishing between these two species.

Both species exhibit gray-brown plumage with darker streaks, a browner tail and wings, a whitish supercilium and throat, and a heavily brown-streaked breast. These features are not reliable for distinguishing between them.
