p.s.

re. unusual nest sites, mentioned by Bob a couple of days ago. forgot to mention that Great Tits have started nest building in the same post box as last year, not far from Llandysul. I've left a note for whoever is on that route Tuesday to ask our manager to give us a "temp. out of use sign." Last year we were too slow and posted mail prevented them being successful. Hopefully, I've spotted it a bit quicker this time.
