Many people have commented on the good numbers of Chiffchaff singing this spring. The first returns from our ringing sessions at Leighton Moss support this view. Looking back over the period 2000 to 2010, in these 11 years we only ringed a grand total of 23 Chiffchaffs in June. This June we have ringed 20 all juvenile birds suggesting good productivity.
These early returns from a difficult month weather wise also suggest that it has been a good breeding season for Willow and Reed Warbler and also Blackcap. However for our main study species -Bearded Tit the population has obviously suffered during the past cold winter. We have only caught 13 this June compared to 77 in June 2010.
