Analysis of information sources in references of the Wikipedia article "Jourdain Society" in English language version.
And just in case you thought egg collecting had stopped, one of the results of the police raid on the annual meeting of the Jourdain Society was the conviction of John Maylin. He pleaded guilty to the possession of 314 Tree Pipit eggs and was fined £500 with £172 costs. The Jourdain Society is named after the distinguished Reverend who was an egg-collector when few people thought how anti-social it was. The Tree Pipit is a delightful little migrant bird currently declining in Britain. Most British birders will never have seen as many as 314 in their lives!
