Given a number of different comments about how abysmal 2012 has been for breeding success, here is some definitive evidence from BTO's constant effort scheme which shows just how poor breeding success has been for our small birds. Follow the link and judge for yourself.
http://www.bto.org/volunteer-surveys/ri ... sults/2012Of 23 small passerines monitored, only one, blackbird managed to avoid the ill effects of all that rain.
I'd just like to add that this data fully justifies why ringing is such an important contribution to our knowledge of UK birds and I'd like to express my admiration and thanks for the dedication and hard work that constant effort ringers put in, especially in Lincolnshire.
