A.M. Verbeek 1966 Aremanaria interpes (2) 14 June Steve and I went to Elson hagoon to check the Turnstone nest I found on 10 June. The clutch was completed. In addition we found two more nests. All three nests are within 150 m. and two nests were 50 m. apart. X' 50m X2 100m X3 The habitat is a series of polygons surrounded by flat land. The males use the top of the polygons as watch posts. Between nest two and three there is a small lake which may account for the distance between these nest. We checked the # of pairs and it looks like we found all nest on that area. One possible reason for the closeness of the nests and thus the small area of the territories is the fact that the area remained snow bound for a long time. With the birds being physically ready they took what was available. 18 June Tried once more to find the nests but did not succeed. A Parasitic Jaeger flew over and was being chased by five birds, suggesting that I am dealing with 3 pairs. 21 June. The Turnstones at Elson hagoon are still incubating. The males repeatedly chased off approaching Jaegers - Parasitic and longtailed. They fly out to meet the intruder when the distance is still some 1/4 of a mile away and continue to harass it till the poor bird is an equal distance flying away from the nest. It looks like other shore birds do not foster the jaegers 23 June Found a nest with 4 eggs in the polygons in the SE corner of Honey Bracket hagoon. The only way to find these nests is to get close to the general area before the male has a chance to
