Holmes, R. 1959 Erolia alpina 15 June Barrow, Alaska No birds of this species were seen in the drum area either in the morning or afternoon. However, in the area rimmed. So, of the drum area, 3 pairs were seen. Flight displays were seen in all three / three pairs and conflict was noted among two. A pair had been sitting on a small patch of exposed tundra and another bird of the 2nd pair flew in their direction. Immediately both birds of the 1st pair took off and chased the intruder for about 100 yards and then both returned to within 30 yards of the orig. location. The bird which was chased circled around and settled near its mate. During the next hour, no conflict was noted; both pairs continued feeding. Along the gas line road, very few pairs were seen ahead during the morning. Only about 6 birds were seen. One female was collected and had not laid eggs yet, although the preniculation patches were very evident. Territorial defense was not observed during the morning, evidently the birds were feeding actively and were not moving around very much.
