Now is the winter of our bird flock delights. As the cold weather grips, birds come together, sometimes in huge numbers, in order to feed safely and effectively, and to keep warm at night. These winter flocks also provide us humans with spectacular entertainment. In recent years, “soup and starling” events have become popular, with audiences gathering to watch their local starling murmurations. Crowds “Ooh and Aah” in wonder as the swirling, clamouring flocks shape-change.
