16th November, 2002 PELAGIC TRIP, WOLLONGONG, NSW, AUSTRALIA.
Report prepared by: P.J. Milburn.
Departed: 07:40 returned at approx. 15:30.
Sea conditions: SSE 1.0 to 2.0m at first then and to 1.5m ENE, dropping
late in the afternoon.
Swell: 1.0 to 2.0m SE dropping through the day.
Weather: Cloudy with drizzle at first followed by brighter periods,
clearing later, 18 to 26°C.
Barometric pressure: 1025 rising.
Wind: SSE 15 kts veering ENE 10 to 15 kts by mid morning.
Sea surface temperature: 17.1 to 21.5°C.
Moderate east to northeasterly winds had been forecast with local storms,
which are favourable conditions for the arrival of unusual species at this
time of year. We were disappointed to find a sea that had been stirred up
by a southerly blow during the preceding 24 hours. A southerly breeze
persisted into the morning making for uncomfortable conditions for our
Fluttering and Wedge-tailed Shearwaters were abundant outside the break
wall. Despite extensive searching through the flocks for other species,
only 1 Short-tailed Shearwater was identified and no Hutton's Shearwaters
were among the Fluttering Shearwaters. Arctic Jaegers were noticeably
absent but several Pomarine and LONG-TAILED JAGERS were encountered
relatively close to shore. Further offshore the abundant Fluttering
Shearwaters were replaced in even greater numbers by Short-tailed
Shearwaters. A solitary Flesh-footed Shearwater and a Wilson's
Storm-Petrel were observed in deeper water on our trip to the edge of the
As we neared the 100-fathom line a Great-winged Petrel and Sooty and
Hutton's Shearwaters were observed close to the boat. In the midst of this
new activity a BLACK PETREL practically flew into our heads to call
attention to itself. This bird was very cooperative and after being banded
followed the boat for several hours.
As a result of the uncomfortable conditions we cruised northeast edging out
to the 200 fathom-line. This phase of the voyage yielded an adult SOOTY
TERN as the only additional species so, disappointed not to have found an
albatross, we headed for home. Shortly after changing course a Cape Petrel
was observed over the wake a long way behind the boat. Holding our
position and berleying we had to wait a very long minute for the bird to
arrive behind the boat!
The homeward leg of our a trip was soon interrupted by the cry of
"albatross", the first of the day, and an adult female Gibson's Albatross
flew past at a distance. We realised that we had to stop the boat again
but few aboard noticed the rock-n-roll conditions as the albatross
approached us. As she settled down to feed behind the boat we also
attracted a small group of Wilson's Storm-Petrels.
As we returned to the edge of the continental shelf we encountered more
Great-winged Petrels and Jaegers, including 2 LONG-TAILED JAEGERS one of
which was a stunning intermediate morph juvenile. Additionally, a first
year White-capped Albatross was observed in the distance.
Shearwater numbers had remained very high inshore and in the relatively
calm conditions of the afternoon we cruised from feeding flock to feeding
flock. Numbers of Little Penguins were observed feeding with the
Fluttering Shearwaters and a lone Arctic Jaeger busily patrolled the area.
A black-and-white shearwater provided the final excitement of the day. The
bird displayed more contrast between blackish upper parts and white under
parts than typical for Hutton's Shearwater thereby drawing attention to
itself. I was surprised to see the typical underwing pattern of MANX
SHEARWATER, a very thin black leading edge and a thick black trailing edge.
The lesser secondary coverts were finely tipped blackish in sharp contrast
to the pure white humeral coverts and axillaries. The undertail coverts
were white and several others on board also observed the typical facial
pattern of the Manx group of shearwaters. The upperparts were uniformly
blackish brown. The bird was not in fresh plumage so clearly had not
fledged recently. Unfortunately, by the time I blurted out 'look at this
shearwater' the bird had already passed the boat as is often the case with
The major highlight for our overseas visitors was the Gibson's Albatross
but truly excellent views of a BLACK PETREL and a late record of Cape
Petrel came close. Good views of several LONG-TAILED JAEGER and the first
SOOTY TERN of the season were very rewarding. The day finished in exciting
but typically frustrating style with a brief but good view of a MANX
SHEARWATER at close range for myself but, unfortunately, receding into the
distance for others.
