Dipper Apology and A Theory

Sorry about my earlier erroneous posting of Martin Brandon's sighting of the dipper which was of course yesterday and not today.

If I might extrapolate three days of dipper data into a theory: it seems that when it's not around it's not seen all day (e.g. today and Tuesday). On the other hand when it is around (yesterday) it's around for several hours (9-12:30 at least). It may therefore be if someone sees it early in the morning then it's worth rushing down there in the hope that it stays around. As I say, it's a bit of an extrapolation but perhaps worth bearing in mind.
