On Wednesday I set out with John Graff and Nigel Jackett on a seawatch centered 
around Cape Naturaliste, SW WA.  The trip was timed to coincide with the 
aftermath of a second very strong front that has resulted in powerful westerly 
winds and wild weather in the south-west over several days. Conditions were 
ripe; seawatches in the Perth region by John and others in the preceding days 
had been quite productive, so we had high hopes for the trip. 

We left early to get to Bunker Bay by first light and it was immediately 
apparent that this wasn't going to be the dream trip we'd imagined.  There was 
very little activity apart from common species such as Australasian Gannet and 
the odd Crested Tern.  John was surprised to see it so quiet in what were 
otherwise good conditions (winds were SW at 25-35 knots).  A bit of fish oil 
dolloped into the surf may have helped to bring in the only tubenoses we saw at 
Bunker Bay: good views of Northern and Southern Giant-Petrels - but it could 
also have been pure coincidence!

After an hour we decided to move to a vantage point on Cape Naturaliste with 
good elevation, the light perfectly behind us, but, unlike Bunker Bay, very 
little shelter from the sleet. Never mind, because there were albatrosses. 

A regular pulse of albatrosses was making its way nearshore from the south and 
disappearing into the open waters of the bay around the headland.  Meanwhile, 
Great-winged Petrels, Black-browed and Indian Yellow-nosed Albatrosses and both 
giant-petrels were appearing from the north-east around the headland and 
winding their way upwind in the opposite direction. It was a great result 
already, but within minutes things started to get even more interesting.  

Watching for the next albatross in the pulse, I picked up a pale petrel coming 
fast towards us along the coast, inshore in the wave-breaking zone.  Through 
the scope it sheared back and forth giving excellent views of both wing 
surfaces in direct sunlight.  It was unmistakeable. Southern Fulmar was the cry 
and John and Nigel both got on to it quickly and revelled in the bird.  Hearts 
pumping, we watched it cruise past and disappear into the bay to the north-east 
over the next minute or so. 

The next big bird of the trip came after a couple of bouts of sleet had seen us 
oscillate between the shelter of some low heath and our scopes.  I got on to a 
large petrel from the other side of the cape showing all-white. It languished 
for a while downwind of the point, flapping more frequently between glides than 
the giant-petrels had done until then.  While I dithered with the ID, hoping 
for a closer look as it rounded the cape and sailed past us as most birds had 
done, Nigel and John were bang on: it was a pale-morph Southern Giant-Petrel.  

Our final seawatching location was from the whale watching platform on the edge 
of the sheltered northern cliffs of the cape.  Because the sea below was 
sheltered, this was less busy than our previous location but there were some 
numbers of Great-winged Petrels and giant-petrels, and John spied the third 
excellent bird of the trip, a juvenile Wandering Albatross majestically working 
its way upwind and around the cape. 

Thanks to John & Nigel for an exceptional seawatch!
