The White Wagtail
Spot the White Wagtail: It Arrives With the Merchant Ships
The white wagtail (Motacilla alba) is a delicate passerine bird of the Motacillidae family. There are 11 different species known in the world distributed all over Europe and a part of Asia. In Iceland, the white wagtail is found all around the country and breeds mostly in lowland areas.

Unveiling the Unique Features of the White Wagtail
The white wagtail is light grey on the back, but the forehead, chin and belly are white. The head, neck and chest are black. The long tail is black and white, and the bird wags it constantly when standing still, hence the English name „wagtail“. The sexes look alike, but the male has more distinguished colour separation, and its headhood is black but greyish on the female.
This small bird weighs about 0.7 oz, the length is about 7 in, and the wingspan is 10-12 in. The white wagtail is a good flyer. It flies in a wavelike style, where it holds the wings close to the body and dives towards the ground. Sometimes, it hangs in the air for a short period of time, like the Arctic Tern.

Stationary in Europe but Migratory in Iceland
The Icelandic white wagtail is a migratory bird that arrives in April-May. In the old days, it was considered to predict the arrival of merchant ships in spring as the birds often rested on ship decks on their long migratory journey. When the first white wagtails were spotted, the first merchant ships soon followed. The white wagtail leaves the country in early autumn and migrates to North-West Africa, where it spends the winter.
Breeding and Feeding
White wagtails secure a territory before nesting, which they proclaim by beautiful territorial singing. The female wraps a nesting basket in a sheltered hideout, often in rock crevices, dense scrubs or human habitats. The nest is insulated with wool and feathers. Clutch size is normally six eggs, white with dark spots that hatch in 15 days. Both parents incubate and care for the young, but unlike most passerines, only a single clutch is played per season.
The white wagtail is insectivorous and is known for its talent to hunt butterflies, beetles and other dipterans while flying. The bird is also known for its resourcefulness when feeding on the ground and is often spotted eating dead insects on car bumpers. Population size is estimated at 20-50 thousand breeding pairs.
Icelanders Respect the White Wagtail
In Icelandic, the white wagtail is called „Maríuerla“, a name that has its origin from the holy Mary. The white wagtail has other old names, such as „maríuatla“ and „friggjarerla“, but Frigg was the wife of Odin in Norse mythology. As the name implies, Icelanders have a deep respect for this beautiful bird, and it is often mentioned in Icelandic poetry.

Five Facts About the White Wagtail

- The white wagtail often nests close to human habitat as there are plenty of flies and insects to feed on.
- In Icelandic legends, it was assumed that the white wagtail could not start egg-laying until it had inserted the hair of a virgin in the nest. In reality, the nest is often insulated with wool and horsehair.
- The average lifespan of white wagtails is about 11 years, but the oldest known became 13 years and eight months old.
