Summary:

A slow-moving anticyclone was located over the Great Australian Bight and a weak low-pressure system was located in the southwestern Tasman Sea . Overnight rain had cleared and a southwesterly airflow continued throughout a fine day.

Black-browed Albatross were hunting for food just offshore and an adult White-fronted Tern homed in on us as we left the harbour. Large flocks of Fluttering Shearwaters were searching for fish over the inshore reefs and several small groups of Hutton’s Shearwaters were observed among them. Australasian Gannets, Black-browed and Indic Yellow-nosed Albatross were also patrolling the area. Several Southern Humpback Whales were moving slowly northwards a couple of miles offshore.

Fairy Prions became evident as we reached 35 fathoms and more White-fronted Terns followed us for a while. Indic Yellow-nosed Albatross joined us continuously as we cruised eastwards. I had just emerged from the cabin after checking our position at the 60-fathom line, when a juvenile GREY-HEADED ALBATROSS flew up to our wake and landed among the Indic Yellow-nosed Albatross. After the obligatory hollering of ‘stop the boat!!’ the bird swam right up to our stern triggering a photographic frenzy. It must have left the nest quite recently since it still had a large tick engorging itself on the skin at the base of its bill. A Campbell and a White-capped Albatross joined us and so did a diomedea albatross that had the appearance of female exulans but was far too small to be that species. Close inspection revealed that this bird was most probably a TRISTAN ALBATROSS. Hundreds of Fairy Prions were around us and a Brown Skua joined the mob at the stern.

We resumed our trip eastwards toward the continental slope and not long afterwards a stunning adult BULLER’S ALBATROSS quartered our stern but then departed. A small group of Oceanic Bottle-nosed Dolphins rode the bow wave for several minutes, much to the delight of some of our international guests. A female ANTIPODEAN ALBATROSS was next in the albatross procession and a Solander’s Petrel presented itself well inside the edge of the continental shelf.

The sudden appearance of nominate Great-winged, Cape and Solander’s Petrels announced our arrival at the 100-fathom line. A second year SHY ALBATROSS appeared as we began a drift-and-berley session. The number of Fairy Prions was relatively low in the deeper water, which was a bit disappointing but a single Wilson ’s Storm-Petrel appeared over the berley trail. A female Gibson’s and a juvenile WANDERING ALBATROSS joined the albatross flock, which included seven species at this point.

Our trip back to port was fairly uneventful in bird terms but we did encounter 3 different groups of Southern Humpback Whales.

It seems that Fairy Prion has well and truly made a comeback to Wollongong waters after a 3 year hiatus but Campbell Albatross were in unusually low numbers.

Highlights:

Another fantastic trip for albatross encounters with excellent views of 11 species of albatross including the first records of GREY-HEADED and TRISTAN ALBATROSS for 2006. Species diversity was relatively high with a total of 19 species of procellariiformes recorded.

25th June, 2006 SOSSA PELAGIC TRIP, WOLLONGONG, NSW, AUSTRALIA.

Report prepared by: P.J. Milburn.

Departed: 07:15 returned at approx. 16:00 .
Sea conditions: slight WSW at first rising to 1.5 to 2.0m SSW by late morning.
Swell: SE 1.0 to 1.5m inshore and 1.5 to 2.0 m offshore.
Weather: Light high-level cloud at first increasing during the day.
Temperature range: 8.9 to 19.3°C.
Barometric pressure: 1018 HPa rising.
Wind: WSW 5 to 8 knots at first increasing to SSW 15 knots later.
Sea surface temperature: 18.1 to 21.8°C.
Primary chumming location: S 34° 30’ – E 151° 19’.

Summary:

A slow-moving anticyclone remained in the Great Australian Bight and a weak low-pressure system was located in the southwestern Tasman Sea . A weak upper-level disturbance generated fresh southwesterly breezes with increasing high cloud forming during the day.

Unusually, Indic Yellow-nosed Albatross outnumbered Black-browed Albatross in the shallow water and, after an influx overnight, Hutton’s and Fluttering Shearwaters were present in almost equal proportions. Fairy Prions were foraging inside the 20-fathom line and we were soon being shadowed by a mixed flock of Gibson’s, Black-browed, Campbell , SHY, White-capped and Indic Yellow-nosed Albatross. The early indications were that we would have another great day of albatross watching.

Just inside the warmer water at the 60-fathom line, we encountered 3 Southern Humpback Whales heading north and as we were watching these the first SOUTHERN GIANT-PETREL of the 2006 winter season circled our vessel a couple of times.

Heading eastwards toward the continental slope prions were all around us but all that offered close inspection were Fairy Prions. We had to venture into deeper water before we encountered any petrels and even then they were few and far between. We began a drift-and-berley session and gradually began to attract some new birds. The highlight of these was an adult BULLER’S ALBATROSS.

An ANTIPODEAN ALBATROSS and a nominate Great-winged Petrel were late additions to the trip list on our way back to port.

Brown Skua was a noticeable absentee following higher than average numbers the previous day.

Highlights:

This was another interesting day at sea with 9 species of albatross being recorded and a total of 16 species of procellariiformes identified. We witnessed the first record for 2006 of the now rather scarce SOUTHERN GIANT PETREL and another stunning adult BULLER’S ALBATROSS.
