Rumours abound concerning the alcoholic potential of the Bohemian Waxwing. Do berries of the Mountain Ash actually ferment and contain alcohol? Dr. Google certainly says they do. Whether alcohol was involved or not, a recent display by a couple of hundred birds confirmed that they are wonderfully acrobatic in their ability to grasp, flip and swallow these berries. I spent about 20 minutes just watching and listening as a these beautiful birds did their Cross Fit Training exercises. Groups of 10 or so birds would swoop down onto a local Mountain Ash, spend a few minutes feeding then fly back to the top of some Elm trees, only to be replaced by the next bunch all dressed in their rust, yellow, red and grey spandex outfits.
