You’d imagine they’re returning birds that have found a reason to come back, if it was a factor in the previous habitat, wintering divers might be a bit more widespread site-wise? Otter activity might be something that increases detectability of carcasses?

KGV res in London seems to attract multiple divers per winter these days and something must be bringing them back! Just a hypothesis but crayfish presence there is obvious, always seems to be a few discarded carcasses around the water

While you’re here Andy, do you reckon you could add Hypsopygia nostralis to the PSL website please? Found it new to Britain exactly a year ago, although surely imported mothdissection.co.uk/species.php?...
