St Helens Tasmania pelagic birding trip report 24 to 26 July 2008

A gentle sea and good light provided excellent conditions for bird observing and photography for all three days, the birding was excitingly productive and highlights were many. Beyond the continental shelf we approached a drifting stern trawler. It was a buzz to see at least 63 Great Albatross scattered around in a "gaggle" the flock composition approximately 2:10 Royal Albatross/ Wandering Albatross. Although such numbers of Great Albatross together in Australian waters are likely to be a record, at the time not much was spoken but you could feel an aura of appreciation on board generated by this magnificent sight.

On each of the three days we enjoyed good views of Sooty Albatross, Southern Royal Albatross, Northern Royal Albatross, Grey-backed Storm Petrel and all the expected birds as well but on the third day we were especially rewarded with multiple sightings of Grey Petrel. Pleasingly nobody missed out on any of the rarer species seen. At each stop we released fresh shark liver mixed with selected fish oils as a light berley trail and this proved a great attractant to the birds; several times its effectiveness could be seen when a large commercial stern trawler passed followed by masses of sea birds comprising hundreds of Albatross, Giant Petrels, and Cape Petrels etc. By releasing a light trail of our berley mix, almost all the sycophantic followers of the fishing vessels were immediately drawn to us.

Departing St Helens wharf at 0700 hrs., clearing George Bay barway at about 07.30, each day we headed for "The Hill", (41 13'S, 148 45'E) an area of up welling currents surrounding a Tasman Seamount about 23 Nm off shore that has proved to be a very productive birding spot. However we followed a different course each day with stops on the way and arriving about 10.00 am and departing about 1.00 pm. Releasing a light trail of berley at most stops; we were soon surrounded by numbers of albatross and petrels. Heading back to shore with more stops on the way we were invariably followed by a loyal squadron of albatross and Cape Petrels. We passed many Common Diving Petrels and other delights on the way back in, the pelagics diminished as we approach the entrance to George Bay. Stopping to observe roosting waders on sand spits beside the channel after passing through the barway, we made our way to port arriving back at St Helens about 3.00 pm. On this occasion the regular charter boat Nifty II was not available so we used the stand in vessel, Norseman III with skipper Gerald Spalding and Paul as crew.

The Weather For all three days the weather was good for pelagic birding with a blocking high hovering over Tasmania. We experienced a lull situated between an extreme front that passed two days earlier on the 21st and an approaching weak front forecast for the 27th. Wind was variable 5 - 15 knots, air temperatures cold to mild and sea surface temperature beyond the continental shelf was an average C14.3.

The bird list. Diversity was good although gadfly petrels and other small procelleraformes were scarce. Pelagic species recorded (30) Total Species recorded 54. For the purpose of our list, pelagic observations = > 2 Nm from land. Coastal observation = < 2 Nm from land. The numbers shown are conservative estimates with the minimum daily count for each species shown in parentheses. I haven't worked out yet, a successful way of including a table within birding-aus posts so decided on a repetitive system showing recording days for each pelagic species. Also included are species links to Wikipedea or where not available, to Ocean Wanderers "Annotated list of the Seabirds of the World" . Opportunities exist to add pictures and expert text to some Wikipedea entries.
