A wonderful early summer day moderated by cooling SE breezes. It has been
a long time since we had a Wollongong pelagic trip in late December so we
left the harbour trying to guess what the day ahead might bring. It turns
out we had we had several pleasant surprises in store!
The water immediately outside the breakwater was a very warm 23.8°C and
with even warmer water expected wide of the continental shelf our thoughts
turned to tropical species.
As we cruised east, Flesh-footed and Wedge-tailed Shearwaters followed the
boat, being pestered by the occasional Pomarine Jaeger. At the 65 fathom
line, we entered a pool of cooler water as the surface temperature suddenly
dropped 0.7°C. Just as suddenly, there were birds (and fish) everywhere
and the first flock included a LITTLE SHEARWATER. Those who had succumbed
to the soporific effects of sun and sea (motion sickness pills too) were
roused by the flurry of shouts?..Hutton's Shearwater, SOOTY TERN,
LONG-TAILED JAEGER, Sooty Shearwater!! It was difficult to decide what to
point the binoculars at! Up to 15 Pomarine Jaegers were harrying the
shearwaters, including a banded juvenile that evaded our best efforts to
At the 100-fathom line we encountered the first Arctic Jaeger of the day
and a White-faced Storm-Petrel, which have proven so elusive this spring.
Large numbers of SOOTY TERN were in view continuously and we scrutinised
them arduously in case there were other species among them. This was
almost surprising since the maximum count was over 150 in view at any one
time. An hour of berleying at the 200 fathom line attracted both Wilson's
and White-faced Storm-Petrel but only 3 Great-winged Petrels. We elected
to cruise into deeper water in search of additional species but as the
surface temperature increased further the number of birds decreased.
At 600 fathoms, the temperature was 24.8°C and few birds were in evidence
so we turned for port. We have had a good record for seeing rarities on
the return leg of the cruise this year and today was no exception. A
STREAKED SHEARWATER was observed in 550 fathoms and a number of
Storm-Petrels were encountered while we were still in deep water. The high
density of birds encountered on the trip out appeared to have dispersed.
Seven species of Shearwater were observed on this trip, including STREAKED
and LITTLE SHEARWATER. The first LONG-TAILED JAEGERS of the summer
provided extended views at close quarters. The number of SOOTY TERNS was
unprecedented being far in excess of anything recorded previously on a
Wollongong Pelagic Trip.
