Rooftop Herons

I was on the phone to Nick o' Sullivan a couple of days ago (he lives in Llanstadwell ) he suddenly started hollering and cursing and I thought the weather must havefinally sent him raving bonkers...
Apparently two Herons were sitting on his roof contemplating the fishpond. Not sure if this is not the pot calling the kettle black, as Nick must have killed a hell of a lot of fish over the years!
