On the 4th of October, 2008 I went on my first pelagic trip. The trip was run especially for Ruth Miller & Alan Davies who are attempting to see more bird species in a year than anyone else. their adventure is called The Biggest Twitch. The pelagic was organized by Zest For Birds a non-profit group that runs these trips regularly out of Cape Town, South Africa.
After an early start we left the harbour on board the Zest II, a converted Navy tender. The harbour brought the usual gulls, cormorants, terns & gannets, as well as a number of Southern Right Whales (Eubalaena australis).
Once clear of the harbour we spotted the first of the pelagic species (and my first lifer of the day) – a White-chinned Petrel (Procellaria aquinoctialis). These were one of the commonest species encountered on the trip.

Also spotted on the way out were Shy Albatross (Thalassarche cauta), Sooty Shearwater (Puffinus griseus), Great Shearwater (Puffinus gravis), Northern Giant Petrel (Macronectes halli), and Pintado Petrel.

A number of trawlers were visible on the horizon & we headed towards one. The crowd of birds in its wake was unbelievable!

Our species total rapidly increased: Atlantic Yellow-nosed Albatross (Thalassarche chlororhynchos), Black-browed Albatross (Thalassarche melanophris), two species of timy storm-petrel: Wilson’s (Oceanites oceanus) and the less-common Black-bellied (Fregetta tropica) which looked like butterflies as they fluttered between the waves.

The species list continued to increase as we followed the trawler’s wake: Sub-antarctic Skua (Catharacta antarctica) and Indian Yellow-nosed Albatross (Thalassarche carteri). Suddenly a cry went up “White back!” (Only 4 Albatross in the region have white backs.) It was a young Wandering Albatross (Diomedea exulans), the largest of all albatrosses having the largest wingspan of any living bird. Though not fully grown it was an amazing sight and definitely a highlight of the trip.

The final new bird seen in the feeding frenzy was a single Southern Giant-petrel (Macronectes giganteus) which differs from the Northern Giant-petrel in the green tip to its bill. (The Northern has a reddish-brown tip.)

Heading back to Cape Town we added one more pelagic species to our lists as fleeting glimses were had of 2 Soft-plumaged Petrels (Pterodroma mollis).
An absolutely fantastic experience that every birder should undertake at least once in their life. I added 16 new species to my life list and had an amazing time.
