Good numbers of Great Cormorant can be seen in the very early morning flying around Dhahran Waste Water Lake. Some of the birds just come and wash, briefly fish and fly off with others staying for longer periods in the area. The species is a common winter visitor to the Eastern Province where thousands have roosted in the trees nearby in recent winters, but do not do so now. They are also abundant in coastal waters from September through March including the Jubail and the Half-Moon Bay area of the Arabian Gulf. The birds in Dhahran are not disturbed by people walking past the edge of the lake and remain on the lake fishing more often than not.
