Leg 1, Day 25.
A very quiet day, that got quieter as it progressed. Even the White-chinned Petrels, which have been our constant companions since leaving Cape Town, gave up and were replaced as the main ship follower by White-headed Petrels. Only one albatross was recorded – a young Grey-headed visited the ship on station shortly before we left at 15h00. Short-tailed Shearwaters were regular before the CTD station, heading south, but dried up in the late afternoon, and from 17-18h00 only a single White-headed Petrel was observed. The late afternoon watch was enlivened only by a solitary South Polar Skua, which headed south like the shearwaters. At only 9 bird species, today was by far the lowest diversity recorded to date:
|Short-tailed Shearwater||160||White-headed Petrel||15|
|Fairy Prion||10||Antarctic Prion||10|
|Black-bellied Storm Petrel||6||Mottled Petrel||5|
|Diving petrel spp.||3||South Polar Skua||1|
