Zitting Cisticola

The zitting cisticola, formerly also fan-tailed warbler or streaked fantail warbler, is a widely distributed Old World warbler in the family Cisticolidae, whose breeding range includes western and southern Europe, Africa outside the deserts and rainforest, and southern Asia down to northern Australia. A small bird found mainly in grasslands, it is best identified by its rufous rump; in addition it lacks any gold on the collar and the brownish tail is tipped with white. During the breeding season males have a zigzagging flight display accompanied by regular "zit" calls that give it its English name. They build their pouch nest suspended within a clump of grass.
