Our Bearded Tit ringing at Leighton Moss RSPB Reserve continues to be productive. We have now caught 30 juveniles compared to only 17 in the whole of 2012. Of these12 had been ringed as nestlings in our wigwam nest boxes, We ringed 21 nestlings so survival has been good and there are probably more to come as we caught two today. July is normally a good month for captures before they start in moult late in the month and on through August and they then become quite difficult to catch
By comparison Reed Warblers appear to be present in smaller numbers than usual. To date we have caught 66 adults this compares with 95 in the same period last year and ringing effort has been very similar. In recent years we have usually just exceeded 200 adult Reed Warblers by the end of the season. Juveniles are just starting to appear now and this usually results in more adults being caught as they move around or start a second clutch. The oldest bird caught so far this year is in its seventh year, a bit to go yet to catch our oldest bird which was 9 years and 314 days after capture and still going strong.
