Motacilla tschutschensis (but see text)
This species breeds in much of temperate Europe and Asia. It is resident in the milder parts of its range, such as western Europe, but northern and eastern populations migrate to Africa and south Asia.
It is a slender 15–16 cm long bird, with the characteristic long, constantly wagging tail of its genus. It is the shortest tailed of the European wagtails. The breeding adult male is basically olive above and yellow below. In other plumages, the yellow may be diluted by white. The heads of breeding males come in a variety of colours and patterns depending on subspecies.
The call is a high-pitched jeet.
Motacilla is the Latin name for the pied wagtail; although actually a diminutive of motare, " to move about", from medieval times it led to the misunderstanding of cilla as "tail". The specific flava is Latin for golden-yellow.
This species' systematics and phylogeny is extremely confusing. Literally dozens of subspecies have been described at one time or another, and some 15-20 are currently considered valid depending on which author reviews them. In addition, the citrine wagtail (M. citreola) forms a cryptic species complex with this bird;[page needed] both taxa as conventionally delimited are paraphyletic in respect to each other. The populations of the Beringian region are sometimes separated as eastern yellow wagtail (M. tschutschensis).
Currently recognized subspecies
Colouration refers to males except when noted.

- M. f. lutea (S. G. Gmelin, 1774) – yellow-headed wagtail
- Head yellow with green neck in males, females like a somewhat more vivid flava female.
- Breeding: Lower Volga to Irtysh River and Lake Zaysan. Winter: Africa and Indian subcontinent.
- M. f. beema (Sykes, 1832) – Sykes' wagtail
- Like flava but head lighter grey, ears washed white; sexes often similar.

- M. f. plexa (Thayer & Bangs, 1914) – north Siberian yellow wagtail
- Males like thunbergi but ears darker, top of head lighter, vestigial supercilium. Females like dull males.
- Breeding: Siberia between Khatanga and Kolyma Rivers. Winter: India, southe-east Asia.
- M. f. leucocephala (Przevalski, 1887) – white-headed yellow wagtail
- Male like flava, but grey of head very pale, almost white. Female like flava females, but head somewhat darker.
- Breeding: North-west Mongolia and adjacent PRC and Russia. Winter: probably India.
The nominate blue-headed wagtail and yellow wagtail form a narrow hybrid zone in northern France. Birds from this zone vary in appearance, but one type, which resembles nominate blue-headed wagtail (except that the blue tones to the head are paler and more mauve and the white of the head is more extensive, particularly on the throat, ear-coverts, and supercilium) is colloquially referred to as Channel wagtail.
In the Pyramid Texts of Old Kingdom Egypt, the yellow wagtail was considered a representation of Atum himself and might have been the first inspiration for the Bennu bird, which, in turn, is the supposed inspiration for the phoenix of Greek mythology.
