Three eggs, no nest.
Yesterday I recalled the old legend of how, when St Bride was sailing to Barra and her boat became becalmed at sea, oystercatchers came to her aid, beating their wings to fill her sails and so deliver her safely to her destination. In thanks, St Bride announced that henceforth oystercatchers would have no need to build nests but could simply to lay their eggs on the ground above high water mark, there to hatch safely.
Well here is the proof! The oystercatcher sitting atop the gravestone in yesterday's blip has laid her three eggs straight onto a gravel path, with not a hint of a nest!
