"The Royal Tit-Watching (Ornithological) Society of Britain is the oldest of the British Tit-Watching Societies. The society was formed in 1824, by Lord Roylott of Stoke Moran, Surrey. Lord Roylott was himself a distinguished ornithologist, and author of 'A Comparison Of The Short-Distance Migratory Patterns of the Blue, Long-Tailed & Bearded Tits' - a book which Sir Charles Darwin acknowledged was "of immense importance in the formation of my theory of natural selection."
