A Raven flew deliberately over the M8 near Bishopton first thing, carrying what looked like an eggshell (I have seen the Paisley birds doing the same, presumably removing discarded eggshells from the nest after hatching). At lunchtime, a Raven and a Cormorant were high over the St James Interchange. In the afternoon, two Long-tailed Tits appeared to be nest buliding close to where I was parking in Cessnock.
