Black-headed Wagtail - Jubail

Whilst birdwatching the Jubail area I came across a very smart looking male Black-headed Wagtail feeding along a dirt track. It was not at all afraid of the car and allowed very close approach as it busily feed on insects. Mid-February is the start of the spring passage for this species and Black-headed Wagtail feldegg is often the first subspecies to occur. The Black-headed Wagtail is part of the Yellow Wagtail complex a group of birds that are common spring and autumn passage migrants, sometimes in hundreds. Thy pass from mid-February to May and again from early August to mid-November with many races identifiable in the field including feldegg, melanogrisia, lutea, flava, thunbergi and bema. In spring the black-headed yellow wagtail feldegg (considered by some as a separate species) is often the first subspecies to occur with bema, flava and thunbergi following. By April, flocks of more than a hundred birds are regularly recorded in cultivated areas. During the autumn peak passage, in October, numbers are higher with flocks occasionally exceeding 500 birds. Occasionally they are also recorded during summer and winter.
