Mild and settled conditions on Saturday 13th November enabled BTO licenced bird ringers Kirsty and John to set up and run another of their popular drop in Bird Ringing sessions. When I came by in the late morning they had already had over 70 birds, quite a number of which were birds they had previously rung in previous years, including this handsome young male Goldfinch pictured above. This bird had been originally rung by the team in 2018, making it 3 years old, which is good longevity for a wild bird. By the end of the day they had recorded 88 new birds and 37 're-traps'. Species included Blue, Coal and Great Tits; Siskins; House Sparrow; Dunnock; Robin, Goldfinch, Chaffinch and a Great - Spotted Woodpecker. If you have never seen wild birds close up it is well worth dropping in on one of their sessions both to see the birds and also learn about them from John and Kirsty who have a wealth of avian knowledge. Information regards the size, weight, sex and age of the birds is recorded and added to national records that inform our knowledge of the population size and spread of the various species. Each bird is given a special ring on its leg with a unique code so that if it is ever re-caught it can be identified and information regards age and dispersion can be learned. Fitting the rings is delicate work and it takes many years for ringers to get their licenses. The next drop in session will be on Saturday 11th December, put the date in your diary!
