White wagtail

Motacilla alba

The white wagtail is a small passerine bird in the wagtail family Motacillidae, which also includes the pipits and longclaws. This species breeds in much of Europe and Asia and parts of north Africa. It is resident in the mildest parts of its range, but otherwise migrates to Africa. It has a toehold in Alaska as a scarce breeder. In the British Isles the darker sub-species the pied wagtail predominates.

The white wagtail is an insectivorous bird of open country, often near habitation and water. It prefers bare areas for feeding, where it can see and pursue its prey. In urban areas it has adapted to foraging on paved areas such as car parks. It nests in crevices in stone walls and similar natural and man-made structures.

The white wagtail is the national bird of Latvia.

Appearance

The white wagtail is a slender bird, 16.5–19 cm in length , with the characteristic long, constantly wagging tail of its genus. Its average weight is 25 g and the maximum lifespan in the wild is c. 12 years. The nominate subspecies ''Motacilla alba alba'' is basically grey above and white below, with a white face, black cap and black throat.


There are a number of other subspecies, some of which may have arisen because of partial geographical isolation, such as the resident British form, the pied wagtail ''M. a. yarrellii'', which now also breeds in adjacent areas of the neighbouring European mainland. The pied wagtail, named for naturalist William Yarrell, exchanges the grey colour of the nominate form with black , but is otherwise identical in its behaviour. Other subspecies, the validity of some of which is questionable, differ in the colour of the wings, back, and head, or other features. Some races show sexual dimorphism during the breeding season. As many as six subspecies may be present in the wintering ground in India or Southeast Asia and here they can be difficult to distinguish. Phylogenetic studies using mtDNA suggest that some morphological features have evolved more than once, including the back and chin colour. Breeding ''M. a. yarrellii'' look much like the nominate race except for the black back, and ''M. a. alboides'' of the Himalayas differs from the Central Asian ''M. a. personata'' only by its black back. ''M. a. personata'' has been recorded breeding in the Siddar Valley of Kashmir of the Western Himalayas. It has also been noted that both back and chin change colour during the pre-basic moult; all black-throated subspecies develop white chins and throats in winter and some black-backed birds are grey-backed in winter.

The call of the white wagtail is a sharp ''chisick'', slightly softer than the version given by the pied wagtail. The song is a pleasant twittering, more regular in White than Pied, but with little territorial significance, since the male uses a series of contact calls to attract the female.

Dutch name witte kwikstaart             latin name motacilla alba The white wagtail is 16.5 to 19 cm long (including tail). It is a slender bird with narrow black and white tail he moves up and down. An adult male has a distinctive black and white pattern on the head. The area around the eye is white, the head cap and thorax are black. The most common among species has a gray back. A subspecies that breeds in the British Isles has a black back and called mourning Wagtail (M. a. Yarrellii). Sometimes this subspecies is considered to be kind, but not according to the IOC World Bird List. Geotagged,Motacilla alba,Netherlands,Spring,White wagtail

Distribution

This species breeds throughout Eurasia up to latitudes 75°N, only being absent in the Arctic from areas where the July isotherm is less than 4 °C. It also breeds in the mountains of Morocco and western Alaska. It occupies a wide range of habitats, but is absent from deserts.

White wagtail is resident in the milder parts of its range such as western Europe and the Mediterranean, but migratory in much of the rest of its range. Northern European breeders winter around the Mediterranean and in tropical and subtropical Africa, and Asiatic birds move to the Middle East, India, and SouthEast Asia. Birds from the North American population also winter in tropical Asia.

Status

This species has a large range, with an estimated extent of more than 10 million km2 . The population size is unknown, but it is believed to be large, as the species is described as "common" in at least parts of its range. Population trends have not been quantified, but the species is not believed to approach the thresholds for the population decline criterion of the IUCN Red List . For these reasons, the species is evaluated to be of least concern. The population in Europe appears to be stable. The species has adapted well to human changes to the environment and has exploited human changes such as man-made structures that are used for nesting sites and increased open areas that are used for foraging. In a number of cities, notably Dublin, large flocks gather in winter to roost.

Behavior

The most conspicuous habit of this species is a near-constant tail wagging, a trait that has given the species, and indeed the genus, its common name. In spite of the ubiquity of this behaviour, the reasons for it are poorly understood. It has been suggested that it may flush prey, or signal submissiveness to other wagtails. A recent study has suggested instead that it is a signal of vigilance to potential predators.

Reproduction

White wagtails are monogamous and defend breeding territories. The breeding season for most is from April to August, with the season starting later further north. Both sexes are responsible for building the nest, with the male responsible for initiating the nest building and the female for finishing the process. For second broods in the subspecies ''personata'' the female alone builds the nest,which is a rough cup assembled from twigs, grass, leaves and other plant matter, as the male is still provisioning the young. It is lined with soft materials, including animal hair. The nest is set into a crevice or hole; traditionally in a bank next to a river or ditch, but the species has also adapted to nesting in walls, bridges and buildings. One nest was found in the skull of a walrus. They species will nest in association with other animals, particularly where available the dams of beavers and also inside the nests of golden eagles. Around three to eight eggs are laid, with the usual number being four to six. Its eggs are cream-coloured, often with a faint bluish-green or turquoise tint, and heavily spotted with reddish brown; they measure, on average, 21×15 mm . Both parents incubate the eggs, although the female generally does so for longer and incubates at night. The eggs begin to hatch after 12 days . Both parents feed the chicks until they fledge at around 14 days, and the chicks are fed for another week after fledging.

Though it is known to be a host species for the common cuckoo, the white wagtail typically deserts its nest if it has been parasitised. Scientists theorise that this occurs because the wagtail is too small to push the intruding egg out of the nest, and too short-billed to destroy the egg by puncturing it.
Wagtail (either Pied or White) I am unsure as to whether this is a Pied Wagtail or a White Wagtail, it was as though it was resting, most unlike the Pied Wagtail that is usually very busily going to and fro along the pavements and roads nearby, if anyone could confirm it would be great Birds,Geotagged,Motacilla alba,United Kingdom,White Wagtail

Food

The exact composition of the diet of white wagtails varies by location, but terrestrial and aquatic insects and other small invertebrates form the major part of the diet. These range from beetles, dragonflies, small snails, spiders, worms, crustaceans, to maggots found in carcasses and, most importantly, flies in the order Diptera. Small fish fry have also been recorded in the diet. The white wagtail is somewhat unusual in the parts of its range where it is non-migratory as it is an insectivorous bird that continues to feed on insects during the winter .
