Seeing a friend at the Library on Friday, he told me about an experience that a very well respected member (and finder of several rarities) of the Yarmouth Bird club was subjected to. He, too, was watching the Waxwings from Lidl car park and he was approached by Lidl's manager to say that he had complaints from people in the houses saying they had seen a person looking through people's windows with binoculars. Of course, he wasn't, he was just looking at the Waxwings feeding either on the Mountain Ash berries or perched on the aerials.
When he had explained what he was looking at, the embarrassed Lidl's manager apologised and bore a hasty retreat.
Birding around housing estates and looking especially for waxwings can be a hazardous pursuit.
It reminded me of a time when I was looking at Waxwings at Tottenham on a housing estate in London and I had rude words shouted at me by teenagers in the neighbourhood.
