Coursers Lane GP/Fields - 26 November 2013

Today's outing whilst D was at work was with the Maple X team, PD, MRB and MBR, to ring an area with the emphasis on Tree Sparrows, with the addition of Buntings and Finches using an area set with wild bird friendly crop. Two of the target species were re-trapped and both had lost their pit tags and had new ones fitted. The pit tags are now embedded within the colour ring where previously they were glued onto it, and these did not always remain fixed to the colour ring. Whilst ringing, Ken Smith turned up to replace the battery on the pit tag reader fixed to the feeding station. It logs the presence of a bird every 15 seconds and is resulting in very detailed records of the Tree Sparrows at the site. There have been a couple of movements to and from the site, and use of pit tags has shown that one of these birds has remained at the site to bred, something conventional ringing may have not picked up, especially considering Tree Sparrows are not easy to re-trap.
