Birds of Saudi Arabia: Winter visitors and spring migrants together

Birding the Jubail area a week ago is quite interesting as you can see winter visitors and spring migrants side by side. I saw a reasonable number of migrants as well as a few winter visitors with wintering birds still around in small numbers including Water Pipit, White Wagtail, Red-spotted Bluethroat and Greater Spotted Eagle. Many of the Water Pipits and some Red-spotted Bluethroats are already in summer plumage and will be leaving very soon for their breeding grounds. Summer migrants were mainly Barn Swallows, Sand Martins, Pallid Swifts and a few Yellow Wagtails of various subspecies but mainly Black-headed Wagtail. A single Citrine Wagtail was present with the Yellow Wagtails and this could either be a winter visitor as some winter in very small numbers or more likely a passage migrant as March is the best month for seeing the species in the Eastern Province of the Kingdom.
