Amerman, Kenneth 1964 21 March 8 - 600 banded on eggs between plot 1 and road to dock. March 9 - Birds solid in former dump areas and to left of transmitter. Only open areas remaining - right of transmitter, both sides of road to transmitter, innermost half of north peninsula. Egg numbers in plots seem to be steadying around 50 except in No. 6. March 10 - Eggs in two new areas - left of transmitter building to edge of road and adjacent to road between plots 1 and 2. Birds sitting to right of transmitter and a few on the road near the building. March 11 - Birds on eggs all the way back to the dock. March 12 - Yesterday the birds were 20 feet away from the antenna enclosure and had eggs to the edge of this line. Today they had filled in another 10 feet but no eggs had appeared yet. March 14 - Birds and eggs right to antenna enclosure. They are advancing slightly down the north side of the causeway also. March 18 - Egg laying seems to have definitely slowed. A few more are laid each day, especially around the transmitter building (some on the road today), but no major influxes have occurred since the birds filled in this area. A few more eggs turn up each day in the study plots; this is probably representative of the situation on most of the island now. The birds moved inward on the north peninsula only about 15 feet more, and slowly; plots No. 6, which was on the edge of the group when it appeared to have stopped and had no eggs. Now has 21. The birds may be moving outward onto the peninsula slowly now.
