@gardencat Hi Joanne, these are quite interesting birds. In the UK, they rarely eat Oysters, mostly Cockles or Mussels. It seems to depend on which food the parents teach them to eat. Also they have two different techniques to get into the shells. Some with a broader, stronger bill, literally batter their way in. Others with a thinner bill prise their way in between the two shells. They seem to live quite long as well, from ringing data one was over forty years of age.
