Alternative names: Grey-backed Wagtail; Long-tailed Wagtail
- Motacilla clara
17-19 cm. A long-tailed, graceful wagtail.
- Narrow white supercilium
- Blackish lores and area below eye, dark-grey ear-coverts
- Mostly grey upperparts, blackish wings, most remiges and wing-coverts narrowly edged white, tertials broadly edged white
- Uppertail dark with white edges, undertail white
- White underparts with narrow black breastband
Sexes similar. Immatures lack (or nearly lack) the breastband.
Three subspecies recognized:
- M. c. chapini from Sierra Leone to Gabon, Democratic Republic of the Congo and western Uganda
- M. c. torrentium from eastern Uganda to Kenya, Rwanda, Angola and South Africa
- M. c. clara in Ethiopia
chapini is probably inseparable from torrentium. May form a superspecies with Grey Wagtail.
Initially called Motacilla longicauda, but this name was preoccupied.
Found along rocky, fast-flowing streams and rivers in forests. Occurs from lowlands up to at least 2000m.
Sometimes in more open habitat in places where African Pied Wagtail is absent.
Feeds mainly on insects. Takes also small invertebrates, small fish and tadpoles.
Picks and darts its prey on the ground or in vegetation, wades in shallow water to pick prey from it and jumps up to catch insects. Also flycatches over rivers.
Breeding season differs through range: May and August to December in South Africa, March and July to November in Malawi, in all months in Tanzania and January to April and September to November in Ethiopia. A highly territorial, monogamous species. The nest is a bulky structure made of leaves, grass, moss and roots, lined with hair. It's placed on the ledge on a riverside cliff, among tree roots by a river or sometimes under a bridge. Lays 1 to 4 eggs.
