Whites Green, Petworth, Sussex, UK. 24th Aug, 2013. Flocking of House Martins (Delichon ubicum) has started in Sussex with more than a thousand birds seen in one flock at Whites Green this week-end. They gather together prior to the mass migrations to their mystery destination in the African continent - this year scientists have attached mini geolocation devices to a number of birds and the hope to be able to solve the mystery of where the birds overwinter.
