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.

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.
