9pm. Cool and still after a hot sunny day. The sun a red dot dipping low across the fields from a cloudless sky. The air perfumed with hawthorn blossom that hung like snow on the dark green branches. And in the air just one sound - well, actually a multitude of sounds - a veritable roar of competing tweets, chirps, trills, warbles and whistles as the massed choir of unseen birds shouted their happiness from the treetops.
For the longest time I just stood in the gathering gloaming and listened to the only Twitter I’ll ever need.
