Onshore winds continuing in the Channel, might keep it in the area for a day or two more?

The number of food-distributing pelagics for one. In much the same way as Nuthatches have probably spread through garden feeders into Scotland in the last few years. Alter a bird's regular food supply and you may alter its distribution.

Just a guess mind.

Spent an hour and a half at Berry Head this morning from 05.50. Sea was pretty much calm - no white horses at all! A few Gannets diving close in and a Dolphin was all of interest early, but things livened up with a small passage of Common (Commic) Terns. In a 20 minute period 7 Arctic Skuas went past, the penultimate one accompanied by a Pomarine Skua. At one point the Arctic took exception to it's slightly larger cousin and made a brief pass at it from below. There was also a smattering of Manx Shearwaters with one Balearic Shearwater trailing the last group. A good sized group of Dolphins kept me amused for a while, but with nothing further going past I headed off.

Unfortunately the amount of food distributed from boats is going to be literally a drop in the ocean ...

Not a lot of chumming goes on, and what does would be a miniscule/negligible addition to the biomass/available food out there.

Nice guess tho!

Thanks Grahame, what a bizarre individual it's turning out to be. I've finally got a window tomorrow, so I'm still living in hope!

That was the bit I wasn't sure about. Are most pelagics just boat trips, without any attempt to lure the species (my only experience was on the Scillonian in 1998)?

There's vastly more fish guts chucked overboard from fishing boats (hundreds, perhaps thousands, of tonnes per year), than there is from birding boats (a few dozen kg per year). The 'chum' component in seabird diets is minuscule and totally insignificant, compared to what fishing boats have been chucking out for decades.
