Small, elegant, confiding passerines with distinctive tail-wagging habit while walking. The function of this tail-wagging is not known, but it might be used to flush crypti, ground-dwelling insects. They are terrestrial foragers, are always found in moist areas near water. They walk along in search of invertebrates that are gleaned from the ground, surface vegetation and even the backs of hippos. They often associate with foraging mammals, feeding on the preuy items they disturb. prey is aquired by 'run-picking', whereby the wagtail struts along and searches for prey, which, once identified, is captured with a quick dash-and-grab. They may even actively chase aerial insects, launching the sally from the ground.
They are monogamous and highly territorial. The nest is a substantial untidy cup of grass and other debris, built by both sexes, placed on the ground or in a cavity, usually near water. They have clutches of 3 -4 whitish or buff egg, speckled or blotched. Both sexes incubate and care for the young.
