K.E. Amewar 1964 Manana were concentrated in the central portion of the wall, where it became highest. A few were also found in valleys between ridges on the landward (south) and S.E. slopes. Wedge-tail shearwater burrows were distributed over the entire landward face up to about halfway. They became more dense in the areas occupied by tobacco plants and on the west and NW slopes, where the Footys were absent. Very densely distributed in the crater also. Population estimates: Sooty Tern - 50,000 pairs (R.C. 50) Wedge-tail - 4,000 (landward slopes) R.C. 20,000 (crater) (guess) Common Noddy - 4,000 (R.C. 50) Bulwer's Petrel - 2 landed, no others seen. Approximately 30% of the Sooty Tern eggs had hatched. All but a very small percentage of those were less than one week old; the remainder were 10 days - 2 weeks old (capulacs 1/4" x 3/4"-1" in area). The oldest chicks were located on the S.W. slopes. Harry examined several Noddy eggs and found no visible embryos, indicating that they have all been laid
