RS Brown 1968 Fairy tern McLean Island 19 Oct. Some odd courts which I fought to enter in her area: 6 eggs 4 medium down chicks 3 Large feathered chicks They were counted along the rocky crest on far (E-NE) side of the island. Practically nothing else nesting over there, and I have little occasion to go there. This species is distributed in fair numbers all about the island, but the large concentrations are on the old rock walls on west side. 26 Oct. 43 birds counted at 2220 about the NW circular wall. 27 Oct. 44 adults were counted flying about the large "ditch" on N side of island at 1130. RS Brown 1968 Common Noddy McLean Island 25 Oct. Regurgitation samples from 10 1/3 sized chicks = between, medium, downy and large feathered young; tending more towards latter age class more allocated between 1830 and 2000 and were as follows: # wt. (gms.) 1 5.2 2 17.9 3 13.6 4 4.7 5 10.5 6 10.0 7 1.3 8 1.5 9 5.4 10 17.0 9.31 Contents (mainly): 100% squid 100% squid 100% squid 100% squid (Sembid) 30% squid, 70% halfbeak 100% squid, 70% Sembid. 100% halfbeak 100% squid 70% squid, 5% Triggerfish, 25% Scanturis. The one sample of triggerfish (possibly pelagic), the halfbeak (Palaemonidae). An estimated 5,000 roosting along SE-SW Lagoon shoreline on mud flats, rocks & Scurumin flats. 26 Oct. A nest survey was done about the large central complex of walls today. Egg + chicks count. The egg count is considered O.K., but for the same area the chicks count is probably low as they hide fairly well in rock crevices. Culmen (mm) Chicks E 35.7 19.3% 13.9 S09 Duvk Ind.
