NAM Verbeek. 1966 Xema salini 22 June We saw at least two of these birds at Ebrovik. We collected one bird on the edge of a stream, later on, on our way back there was an other bird on the same spot. The stream was shallow there so that grasses stick out of the water. Perhaps this grass acted as a strain. 25 July At Meade River I saw two birds, about 3 km S.E. of Camp. 26 July One single bird about 2 km S. of camp. 17 Aug. Back at Barrow, we saw several large flocks of adults and immatures along both sides of the sand spit leading to Point Barrow. This is apparently a favorite place, rich in food, for the gulls have been gathering here for at least a week. 27 Aug. One bird along the beach. 3 Sept. Small flocks of these gulls flew along the shore towards Duck Camp. I saw the same movement of birds yesterday. A large concentration, mostly immatures at Point Barrow. There were an estimated 500 birds.
