Yellow Wagtail

The Yellow Wagtail is a migratory songbird of damp grassland and farmland, often seen following grazing livestock to catch disturbed insects.

Its plumage is dominated by yellow underparts and an olive-green back, without the strong grey or black-and-white contrast seen in its relatives.

It is a summer visitor to much of Europe, wintering in sub-Saharan Africa, so feathers are typically only found during the warmer months in its breeding range.

Size & Shape

• Tail is proportionally shorter than the Grey Wagtail's, though still long for a songbird of this size.
• Wings are slim and pointed, suited to long migratory flights.

Color & Pattern

• Back and crown feathers: olive-green to greenish-yellow, without the blue-grey tone of Grey Wagtail.
• Underparts are bright yellow from chin to undertail in adult males; females and juveniles are paler yellow, sometimes washed with buff.
• Head pattern varies somewhat, but British birds typically show a yellow eyebrow.
• Wing feathers are dark brown with pale buff-yellow edging forming wing-bars.

Similar Species

• Distinguished from Grey Wagtail by the olive-green (not grey) back and shorter tail; distinguished from Yellowhammer by slimmer build and lack of chestnut rump.

Overall Plumage

Olive-green upperparts and bright yellow underparts throughout, with a variable head pattern.

Sex & Age Differences

Males are brighter yellow below with a cleaner head pattern; females and juveniles are paler, sometimes with a buff or whitish throat and less saturated yellow.

Molt

A complete molt occurs on or near the African wintering grounds after migration; a partial pre-breeding molt sharpens plumage before the return journey north.

Habitat

Damp grassland, water meadows, arable farmland, and pastures, often near grazing animals.

Range

Breeds across much of Europe and western Asia; a long-distance migrant wintering in sub-Saharan Africa.

Movements

Fully migratory; present in breeding areas only from spring to early autumn.

Behavior

Forages actively on the ground, often running around the feet of grazing livestock to catch flushed insects.

Diet

Feeds on flies and other invertebrates disturbed by grazing animals or farm machinery.

Nesting

Builds a grass-lined nest on the ground, hidden in vegetation in a grassy field.

Voice

A thin, sweeping 'tsweep' flight call, distinct from other wagtails.

Field Notes

Feathers showing yellow underparts paired with an olive-green (not grey) back, found in damp grassland or farmland in summer, point to this species.
