R.S.Brown 1968 Fairy Tern (3) McLean Island 19 Oct. Some old counts which I forgot to enter in here are: 6 eggs 4 medium, downy chicks 3 large feathered chicks These 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 low 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. 24 Oct/ 44 birds were counted flying about the large "ditch" on N side of island at 1130. R.S. Brown 1968 Common Noddy (4) McLean Island 25 Oct/ Regurgitation samples from 10 1/3 sized chicks = between, in downy and large feathered young; tending more toward latter of these more collected between 1830 and 2000 and were as follows: # wt. (gms.) contacts (varies) 1 5.2 100% squid 2 17.9 100% squid 3 13.6 100% squid 4 4.7 100% squid 5 10.5 100% fish (Combida) 6 10.0 30%org, 70% halfbeak 7 1.3 10% squid, 70% combida 8 1.5 100% halfbeak 9 5.4 100% squid 10 17.0 40% squid, 5% triggerfish, q.31 25% combida. The are examples of triggerfish (justably Scherria), the halfbeak (julii Hemiramphus). An estimated 5,000 soaring along SE - SW layon shorelines or mud flats, Ntho & Sesuvium 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.
