“We have a pair of swallows that have built their nest in exactly the same place on a wooden beam in the tool shed for the past six years, and it is amazing to me how they fly off thousands of miles to North Africa in the autumn with their young and then six months later they find their way back to the same tool shed at Gypsy House, Great Missenden, Bucks. It’s a miracle and the brainiest ornithologists in the world still cannot explain how they do it”
