I know some people can't stand them as 'alien' invaders but I can't help admiring the way these bright tropical creatures have adapted to the British environment. I was visiting my son in London a couple of weeks ago and we took our granddaughter to the local park for a Sunday stroll. Suddenly from the trees we heard an extraordinary call and this drew attention to numerous parakeets that were feeding on acorns, so well-camouflaged against the oak leaves. It struck me that their only competition in London for that particular food source would be that other 'alien' invader the Grey Squirrel.
