PELAGIC TRIP OFF EAGLEHAWK NECK, TAS

OBSERVERS: Paul Ashley, Sheila Ashley, Helen Cunningham, Seb Galloway, Malcom
Graham, Mona Loofs-Samorzewski (recorder), Steve Pratt, Effie Pryer, Carolyn

BOAT: Pauletta Charters, with skipper John Males and deckhand Hugh Smith.
There was an air of excited anticipation among the birders who arrived at
Pirates Bay for the first of a full weekend of pelagic trips out of Eaglehawk
Neck. For some, the knowledge that large numbers of mottled petrels had been
seen a week before set the pulses racing, while for some less experienced
participants, a combination of nerves and excitement contributed to the general
buzz as we waited for the boat to come alongside. The weather was not good with
drizzle and fog restricting the visibility to around 300m when we left.
A moderate east-northeast breeze of around 15kts created a low sea against a
southwesterly swell of around 1.5m, so the ride out was reasonable but a little
choppy. We chose to head due east out of Pirates Bay and Mottled Petrels
started appearing around 1 nautical mile
outside the Bay. A lone great albatross also surprised us well inshore of the
line to the Hippolyte Rocks. Despite the fog, it was not too cold but the
visibility worsened to around 100m. Birds were darting in or out of the fog,
providing some identification challenges.
Three unidentifiable ‘cookilaria’ petrels passed by inshore, disappearing into
the gloom as quickly as they appeared. We started to see a number of Mottled
Petrels well inshore and a couple more ‘cookilaria’ petrels remained
unidentified as they passed by the boat on our way to the continental shelf.
Some sharp shooting by the photographers in the gloom allowed one to be
identified after the trip as our first Cook’s petrel. A second Cook’s passed by
a short while after we passed into
offshore waters, without stopping to pose for pictures. Further offshore, the
fog started to burn off, sunshine was abundant and visibility improved for the
rest of the morning.
We started the first berley at 9:40 over 350 fathoms, drifting slowly until
11:20. At the first stop an Arctic Tern flew in to the boat and gave fantastic
views and photographs as it hovered over the stern. Several Gibson’s
Albatrosses that came to the first berley stop were joined by an immature Snowy
Albatross at the back of the boat and they remained with us for the remainder
of the trip, with one following us right back to Pirates Bay. During the day,
Mottled Petrels were surprisingly confiding and one stayed with the boat for
the best part of an hour at the berley stop. A White-Headed Petrel was another
highlight as it passed close to the boat in the sunlight. Several Wilson’s
Storm- Petrels were seen together in the slick and 4 Australasian Gannets
passed close to the boat while we were stopped.
After the first stop, we moved further south to a second berley stop over 450
fathoms, at 16nm from shore. The wind swung further north during the second
stop and the sea calmed slightly. The continued sunshine was a nice change from
the earlier fog.
At the second berley stop a lone Southern Royal Albatross joined the other
large albatrosses at the boat. The majority of the Shy Albatrosses and both
Campbell Albatrosses from the first stop stayed with us. A couple of Cape
Petrels joined the party at the boat as well. A couple
more Gould’s Petrels passed by at this stop, but were not inclined to hang
around.
At 13:00, we reluctantly started back to port, and two more Mottled Petrel
provided excellent views in offshore waters. We docked at 15:00.
The list for the day totalled 29 bird species and 1 mammal species and a good
time was had by all!
MAMMALS: Two Australian fur seals were seen, one offshore and one in pelagic
waters, although the sea conditions may have prevented more sightings and we
had stayed away from their usual haunt around the Hippolyte Rocks.
Another trip passed without sighting any dolphin species and the skipper
reports that the offshore bottlenose dolphins appear to have left the area, as
they have not been seen for several months.
BIRDS: We tallied 29 species beyond the entrance to Pirates Bay, which is a
good number for a Tasmanian pelagic. Without doubt the highlight was the number
of Pterodroma species, which was exceptional, and the close views of several of
the rarer species.
