A fantastic number of Chiffchaff present along the River Colne side of the lake all making the most of the mild weather catching many of the emerging insects flying around. There has been a Siberian Chiffchaff amongst them recently but I did not see it today. One of the birds I photographed was sporting a BTO type metallic ring but I'm unable to read it despite my best efforts.
