The id of chestnut-eared bunting and Little Bunting has suddenly become a hot discussion topic.
However, may I raise a third option?
This bird looks like a Rustic Bunting to me, though I have no experience on this species.

Chiu,

yes, you are right. Having go through a more detail of Rustic, it should has white wing bars, reddish flanks and no such bold lateral crown stipe. So, Rustic can be rule out.
However, I've never seen a Chestnut-eared has a distinctive lateral crown stripe and brownish median crown stripe.  It should be a Little then.
If you have the concept of size, Little usually give a small-sized impression .
