It followed the plover not only in a straight line, but also in a zig-zag course, harassing the plover for about 600 feet as it flew east & then north out from the island. This species is settling + laying eggs in areas which it did not occupy for the entire length of the breeding season last year. They are now in the lagoons along the west shore + extending eastward + northward across both roads. One reason for this may be the Ammophila which has become much more dense in the area between plots 1 & 2. This area was practically bare + unvegetated last year at this time. Out of the 100 birds banded + painted green on their breast in the plot of birds without eeggs (+7), 3 have already been seen outside the plotted area. The plotted area is along the south wall of the old transmitter building. This area was set aside to determine movement of birds which have not laid eggs. Two days after banding one was found along the west roadway incubating an egg (about 300 feet from the plotted area). Two others have been observed west of the plotted area also, however, neither have eggs. There are
