SAM Verbeek 1966 Pluvialis dominica (1) June 3 We saw two males, about ½ of km. from each other feeding on the exposed patches of tundra. One of them, when pressed by our approach flew up and went into the slow- wing-beat flight display which goes accompanied by a single repeated call. June 4 Saw no Golden Plovers today. June 5 No plover's today. June 6 Between 09:00 and 11:00 we saw only one plover feeding on an exposed area. 8 June Saw two Golden Plovers today on the N. shore of Wohlschlag Lough. They are difficult to approach. A third bird flew over Pitellka's plot late in the afternoon. This bird was displaying, flapping with slow wing beats and making the single repeated call. 9 June Two Golden Plovers on S.E shore of Honey Bucket lagoon. In their feeding behavior they walk around in short burst taking some steps and then standing still. Sometimes they will then peck at something, at other times they walk on for a few steps. It almost seems that they either feed by visual clues or perhaps they hear. They do not turn their heads sideways as Robins do, however. I think visual clues are the most important. 10 June One bird on a small snow-free patch in the middle of Central Manola. 14 June Noticed two birds halfway in the act of copulation on the east side of Pitellka's Plot. When the male dismounted he flew off in a half circle and landed some 30 meters behind the female. The female did not start preening but fed instead
