Hi,
This is my first decent shot of the MotAlb Yarrellii.
The Yarrellii is the resident variety of MotAlb in the British Isles.

The White Wagtail (Motacilla alba) is a small passerine 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.

This 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.

This is a slender bird, 16.5-19 cm in length, with the characteristic long, constantly wagging tail of its genus. The nominate subspecies Motacilla alba alba is basically grey above and white below, with a white face, black cap and black throat.

The resident British subspecies, the (British) Pied Wagtail (M. a. yarrellii) exchanges the grey color with black (or very dark grey in females), but is otherwise identical in its behaviour.

It is likely that the differentiation of White Wagtail into two subspecies in western Europe has arisen because of the partial isolation of the mainly resident British form, although M. a. yarrellii now also breeds in adjacent areas of the neighbouring European mainland.

In addition, there are a number of other subspecies, the validity of some being questionable. They differ in the color of the wings, back, and head, with some (such as the Masked Wagtail, M. a. personata) having an all-black head with a white face mask, and the Moroccan Wagtail (M. a. subpersonata) being somewhat similar to a grey-backed white-throated African Pied Wagtail.

Here you can see the bird hunting for some tasty bites on the edge of the river. A vey characteristic pose. Also you can clearly see the black back; the difference between the MotAlb Alba and Yarrellii.

Thanks for stopping by.
