No, not that I know of, although for some reason I do find it amusing that they sit around on a trough. But that's me and my warped SOH. I'm not sure I found the trough - though I had one in my sights the other weekend. I'll keep watching it. You could see two Lapwings from where I stood (wonder if I'm close).
Oh dear, probably not then. There is a Xav who has posted a few times on another site about Mandarins sitting on a water trough somewhere where I walk, so I asked that Xav about it.
Yes, a better day today! :-D
