An anticyclone located over southern New South Wales generated pleasant conditions for a pelagic excursion. The May trip falls between the departure of the summer visitors and the main arrival of winter species. Rarities often occur on the May trip (Masked Booby a first for Wollongong last year) and with the warm current still running but strong southerlies during the preceding week anything seemed possible.
Three Little Penguins were readily viewed in the calm waters just outside the harbour. At the 20-fathom line 2 adult Indic Yellow-nosed Albatross joined us and a few Fluttering Shearwaters zoomed past. An adult dark morph Arctic Jaeger enjoyed harrying our trailing flock of Silver Gulls. Unfortunately, the gulls outlasted the Jaeger and followed us for the remainder of the day.
As we cruised due east we found a young male Australian Fur-seal that had rounded up a school of baitfish and attracted a flock of seabirds all on its own. We were continuously joined by Indic Yellow-nosed Albatross of all ages that followed for a while and then peeled off. Among these was a third year White-capped Albatross that appeared to have been soiled by light fuel oil. There was cetacean activity in about 85 fathoms of water and we were able to identify Risso's Dolphin and Indo-pacific oceanic Dolphin in the same area. Among the birds following the dolphins was a dark morph Pomarine Jaeger.
The waters at the edge of the Continental Shelf were unusually quiet so we ventured further east into deeper water without stopping. At the 400-fathom line we found warmer water and immediately sighted the first Solander's Petrels of the day. We encountered another warm-water front at 500 fathoms and ended the morning with a drift-and-berley session. Several Campbell and an adult Black-browed Albatross were upon us before we even stopped the boat. The birds that had been following stayed with us but apart from Silver Gulls no other birds came in.
The cruise back to port was more productive than our journey east. A female Gibson's Albatross flew up the wake and came to the boat soon after we had stopped to berley. After everyone had taken photos the SOSSA banding team netted the bird. The bird already carried an Australian band and had been banded originally by SOSSA at Wollongong, NSW on 12 July 2000. The bird was in very good condition and judging by the heavy moult was not currently engaged in breeding. Resuming our westward course, it was not long before an adult White-capped Albatross attended us at close quarters. The sea was glassy smooth and it was wonderful to see this magnificent bird at such close range mirrored in the blue ocean. Even as people reached for their cameras the White-capped was upstaged by a magnificent freshly plumaged adult BULLER'S ALBATROSS. Seabird numbers increased as we reached the edge of the Continental Slope in an uncanny contrast to our observations (or lack thereof) earlier in the day. The first Brown Skua of the winter appeared and made repeated passes overhead despite being mobbed by the horde of Silver Gulls. One of the charter boats from Wollongong had reported a giant petrel in 40 fathoms earlier in the day and, perhaps the same bird, one appeared in mid afternoon. A couple of very determined Silver Gulls tried to repel this bird but eventually it approached the boat and was identified as a NORTHERN GIANT-PETREL. Close inshore a single Hutton's Shearwater and a juvenile White-fronted Tern were the finishing touches to a very enjoyable day at sea.
The first winter seabirds of 2004, a NORTHERN GIANT-PETREL with six species of albatross, including Gibson's and BULLER'S ALBATROSS.
