Breeds from Europe, northwest Africa, and most of Asia east to Kamchatka, though absent from northeast Europe and northwest Asia between Sweden (where a recent colonist) and the Urals. In western Europe mainly sedentary, elsewhere migratory, wintering south-west to Gambia, south to Ethiopia, India and south-east to New Guinea.

[edit] Taxonomy

[edit] Subspecies

Three to six subspecies recognized. Clements[1] and IOC[2] accept only three:

  • M. c. cinerea:
  • M. c. patriciae:
  • Azores (Furnas and São Miguel)
  • M. c. schmitzi:

Other authorities, including HBW[3], split three additional subspecies from the nominate:

  • M. c. robusta:

Breeds by fast-flowing streams in rocky upland areas; more closely tied to running water than other wagtails. In winter, a little more widespread away from water, including in city centres.

[edit] Behaviour

Hyperactive, with constantly bobbing tail.

[edit] Flight

Undulating flight. Often hovers when feeding in the tree canopy and over water.

[edit] Diet

Aquatic and waterside invertebrates, including insects (often caught in flycatching sallies), small freshwater shrimps, and also occasionally small fish fry.

[edit] Breeding

The nest is built in rock crevices, often next to (or even behind) a waterfall.

[edit] Vocalisation

Call: a sharp tzt-tzt, much more incisive and harder than White Wagtail.
