Southport Pelagic Trip 4/7/09 (Paul Walbridge)

Post by Mick Atzeni »

Once again, thanks to Paul for permission to use his reports towards our seasonal records within 250km radius of Toowoomba.

It all helps towards putting birds - and birding - in southern QLD/northern NSW into better perspective, season to season, in a forum largely dedicated to sightings in this region. Nothing's constant and too much is taken for granted about the "common stuff", whose whereabouts, movements and numbers locally are often just as perplexing and intriguing as they are for the uncommon and cryptic species.

Cheers :D

Southport Pelagic 4/7/09

Hi All, the Weather Bureau announced a strong wind warning late on
Friday the 3rd for south east coastal Queensland waters. Based on our
local knowledge and what we believed would happen during the next day,
the skipper and myself decided to go ahead with the trip out of
Southport. We hadn*t been out since April, so stuff it!

Vessel: 37ft monohull M.V. Grinner
Skipper: Craig (Grinner) Newton
Deckhand: Gailforce.
Pax: Paul Walbridge (organiser & leader), Dave Stewart, Rebecca Ryan,
Peter Ryan, Owen Prouse, Brian Willey, Heyn De Kocq, Rod Gardner, Rob
Morris, Alex Ferguson, Andy Jensen, Greg Anderson, Inger Van Dyke,
Richard Baxter.

Weather conditions: A cold front was approaching south east Queensland
which was supposed to bring with it gusting 25-30 knot W-SW winds but on
leaving the Seaway, winds initially from the NW at 10-15 knots, rising
to 20 knots on occasion in open waters, turning more westerly. A virtual
cloudless day with excellent visibility, maximum air temp. 20*C,
barometer 1016 hPa.

Sea conditions: On leaving the Seaway, fairly flat seas on .5 metre
swell, which gradually built up on approaching more open waters and by
the widest point had reached 1.5 metre seas on up to 2 metre + swell.
Current at widest point just 1.5 knots N-S. Sea surface temps. 18.7*C
inshore, to 21.0*C at the Shelfbreak and 22.5*C at the widest point, in
Slope waters.

Left the Seaway at 0710 hrs and travelled out towards the Shelfbreak,
stopping on just a couple of occasions, reached the Shelfbreak at 0950
hrs and the final drift point at approx. 1045 hrs about 52 kilometres
ENE of the Southport Seaway. Drifted ESE at 1.5 knots until 1325 hrs
when headed for home. Arrived back at the Seaway at 1700 hrs, total
duration of trip 9hrs 50 mins.

On leaving the Seaway, no trawler or charter boat activity, just a few
small boats so very little bird activity save for a few Australasian
Gannets, Crested Terns and Silver Gulls. Two separate pods of Humpback
Whales were sighted a few kilometres offshore, one whale in particular
putting on quite a display and photos taken. Nothing much else
traversing the Shelf, just some Hutton Shearwaters and one Fluttering
Shearwater plus a couple of Gannets.

Just after crossing the Shelf break things started to appear including
the first Providence Petrels, the first Yellow-nosed Albatross of the
day and a pod of approx. 100 Melon-headed Whales, always a welcome
winter sighting up here. After pulling alongside the Melon-heads for
photos for a few minutes we headed for our drift point at the
*Rivieras*, a system of ridges and canyons, well known to
fishermen. Providence Petrels began to appear immediately along with the
first Black-bellied Storm Petrel & the first juv. Northern Giant Petrel
cruised in, laying claim to the berley bag floating astern.

At this point I witnessed one of the most beautiful sights I have ever
seen in the ocean, I thought Mahi Mahi were stunning looking fish but
this monster left them for dead!! Just astern of the vessel and just
under the surface a 2.5 metre apparition appeared, pale shiny variegated
green with amazing vertical bands of fluorescent purple. It was a
massive Striped Marlin, unreal! I didn*t have my polarising filter on,
so the photo opportunity was lost.

Numbers of Providence Petrels were noted coming in plus more
Black-bellied Storm Petrels and Wilson*s Storm Petrels plus the lone
Cape Petrel for the day. Then the real surprise packet for the day
arrived in the shape of Southports* first ever July Tahiti Petrel, it
seemed surreal watching this predominately summer bird cruising past a
Northern Giant Petrel and Yellow-nosed Albatross. Tahiti Petrels have
now been recorded in all 12 months of the year off Southport. Just as we
turned around for home, heading back up the slick, 3 Yellow-nosed
Albatrosses appeared along with a slightly mottled, older, Northern
Giant Petrel.

Cruising back toward the Shelf, another juvenile Northern Giant Petrel
approached the vessel from astern and sometime later when well back into
Shelf waters two more Yellow-nosed Albatrosses appeared along with a
juv. Black-browed Albatross. Approaching the Seaway, just a few more
Gannets were added to the score on what was for most, a great day
birding out in the southern Coral Sea in winter.

Wilson*s Storm Petrel * 5 (2)
Black-bellied Storm Petrel * 4 (2)
Black-browed Albatross * 1
