A pleasant albeit breezy summer day and, although there were plenty of white caps by mid afternoon, the sea was not too uncomfortable. For those who keep an annual bird list and visitors from overseas January is always a great trip, while for others it is always something of a mystery package. A high pressure system was located in the Tasman Sea that had generated north easterly onshore breezes for several days so we were hoping for a good day.
We encountered reasonable numbers of shearwaters and a few jaegers inshore, with Short-tailed Shearwaters being present in unusually high numbers for the season. However, much of the cruise to the continental slope was fairly uneventful.
As expected, seabird numbers increased markedly at the 100-fathom line. The threat of a strong northeasterly wind later in the day made us reluctant to venture too far east into deeper water so we headed northeast instead. The weather did not allow us to drift and berley as we would have liked to. During this part of the trip we observed an adult SOOTY TERN and 2 LONG-TAILED JAEGERS.
As we commenced our trip back to port we came upon a lone White-faced Storm Petrel. A large smoke plume drifting down the coast from Kurnell, to the south of Sydney, reminding us of the tribulations of drought and the bushfire awaiting us back on land.
An adult SOOTY TERN and 2 LONG-TAILED JEAGERS were identified amidst large numbers of the usual summer seabird species.
