Tom Raven at Steart and Rog Musgrove at Wall Common had more birds (though nothing out of the ordinary - Manx and Fulmars mainly), which suggests they mostly stayed further out. Would have been distant or invisible from Burnham.
Due to be a howling westerly this afternoon, which should be good, although a calmer period in between may have allowed birds to move back out (the only report of note so far today is a Leach's Petrel off Porthcawl on the Welsh side, moving west).
A single Leach's Petrel in the Parrett estuary this evening - seen by Brian Hill off Huntspill Sea Wall just before it was killed by gulls, and by me off Burnham shortly after they started playing with the corpse. Oh well!
Manx Shearwater numbers difficult to judge, as they were milling about in the river mouth and behind Stert Island, but probably at least 12-15 birds involved, and quite possibly more.
The only other seabird was a Guillemot which was also attracting unwanted attention from the gulls - I fear the worst for it.
A couple of Whimbrel, and a Peregrine scaring the cr*p out of the waders over the Steart side were the other species of note.
