On Sat am I was in my local Lidl and there is a magpies nest on the other side of the road across from the car park. I was with the kids and we watched a big carrion rob the nest. Despite being mobbed by the pair of magies the carrion was not going to be put off and into the nest it went and obviously plundered the contents. We watched it for a good five minuted before it departed having done its work. Intresting education for the kids, as we were within 20 yds of the action.
Urban carrions also seem very big and I still have not been able to get the close resident who will be plundering the vicinity.
