Forgotten Fields

I also photographed this bird perched on a stalk of wheat. I am unable to identify it; all I can tell, by the shape of its bill, is that it is insect-eating. I suspect it is a Cisticola; perhaps Levaillant’s Cisticola¹ (Cisticola tinniens) as I saw it near a river and according to my bird guide, it is found in marshes and grassland.

1. Update: I am now convinced I have identified it correctly, all my searches confirm it.
