After a strong westerly blow on the day before, the wind dropped off
overnight to provide a picture-perfect Sydney spring day for our pelagic -
albeit, the ride was quite bumpy in the morning with a good swell running.
It is always a special day offshore when we record twenty species and we
reached this mark late in the day with a Northern Giant-Petrel. Although
there were no major rarities, a White-headed Petrel was the first for this
year off Sydney and yet another Buller's Albatross record means that we will
have to change our mantra of 'the four usual albatross species' to make it
five from now on.

Surface water temperatures were down from last month in a narrow range from
15.2degC to 15.5degC. We departed Rose Bay Ferry Wharf (the public wharf
being under repair) at 7.05am and returned at 3.35pm. Sea conditions were
quite lumpy with a 1.0m sea on top of a 3.0m swell although this did
moderate during the day - and the ride home was quite comfortable with the
south-easterly swell giving us some surfing opportunities. Winds were a
little stronger than forecast at about 15 knots from the south-west and
easing to 10 knots from the south after lunch. Unfortunately, several people
succumbed to sea sickness which was a shame because it really was a good day
out on the water.


We left Sydney Heads with a complement of only 14 passengers with visitors
from the USA, Canada and the UK together with a contingent of local birders.
As we headed out into the 3 metre swell, the ride was reasonably comfortable
as the waves were not particularly steep. Our first sightings were some
Hutton's Shearwaters (a lot more of this species today than we usually see)
and the first returning Wedge-tailed Shearwaters of the spring, although not
in great numbers. Despite the fact that there were not large numbers of
birds around, there was  always something to see all the way out to the
shelf and the Abysmal Plain did not live up to its name today. As we motored
out, we added Black-browed Albatross (mostly juvenile birds), Australasian
Gannets, Brown Skuas, Shy Albatross (mostly juvenile White-capped),
Yellow-nosed Albatross and a few Fluttering Shearwaters to the tally. At
about the fifteen mile mark, we were visited by a small pod of Short-beaked
Common Dolphins which rode on our bow for a while - these turned out to be
our only dolphins of the day.

As we approached the shelf break, we began to see the odd Providence Petrel
and our first Wandering Albatross of the day put in an appearance. A late
call on our only Buller's Albatross of the trip resulted in most people
getting only distant views of it as it circled around behind the boat
refusing to come in any closer. When we started our first drift at Brown's
Mountain, there wasn't a bird to be seen and I had some concerns as to how
things would turn out. However, the odd albatross and Providence Petrel
began to drop in and, after a bit of a wait, we began to get a good flow of
birds to the slick. Both White-faced and Wilson's Storm-Petrels gave really
good views and a few Great-winged Petrels came in to provide everyone with a
good comparison with the more numerous Providence Petrels. After motoring
back to the top of the slick and starting a second drift, a couple of Cape
Petrels (nominate race capense) put in an appearance followed shortly
afterwards by a very obliging Southern Giant-Petrel. An Australian Fur Seal
was seen close to the boat but only briefly by a couple of people and then
the bird of the day, in the form of a White-headed Petrel came by and was
seen by most people on board. September is a peak month for this species
but, instead of the five or six birds in a day that we used to see ten years
ago, we are lucky to get even one these days - a decline in numbers or just
a change of habits?

It was soon time to head back to Sydney and, shortly after leaving Brown's
Mountain, we had our first of two Northern Giant-Petrels of the day, much to
the delight of the overseas birding contingent. We came across our first
Humpback Whales of the day shortly after leaving the shelf and the two
animals showed very well to all on board although there were no gymnastics!
Another two pairs that we saw on the way back were not so obliging and the
views of these were at greater distance. As we approached Sydney Heads,
there were large flocks of Wedge-tailed Shearwaters and Fluttering/Hutton's
Shearwaters feeding around what were almost certainly schools of Australian
Salmon and these wheeling birds made for a great spectacle to complete a
very enjoyable day.
