Altcar Withens

There's currently a few thousand geese feeding on fields at Altcar Withens, just outside Formby. Two days ago the snow goose was with them, but I didn't see it yesterday or today. Amazing how a large white bird can go missing for long periods, especially when it's associating with the well watched Lancashire Pink-footed geese flocks. Prior to Sunday it hadn't been reported since 28th October! I'm pretty sure that it wasn't in the Rainford area during that period because I and others have watched that area extensively over the past few weeks so where's it been? And where's it gone now? If it was feeding here two days ago with all of these geese, you'd surely think that it was a reasonable bet that it would still be here?
