Whilst birding the Dhahran Hills Cricket and football Fields in mid-September I found several hundred Yellow Wagtails allowing close views and photos to be taken. They varied in plumage considerably and there was more than one sub-species present but the most common appeared to be flava. The Yellow Wagtail is a common passage migrant with various subspecies occurring, but they are much commoner in the spring than the autumn. Autumn numbers are still relatively high with tens of birds generally seen during the migration period from late August until late October. This is the first time I have seen this high a number of birds together hopefully indicating a good autumn to come.
