The 2008 breeding season.

Results have been just released on the 2008 UK breeding season. 2008 was a cool wet summer being wettest in July and August, thus affecting those birds that have later broods. This following on from the wet summer of 2007.
Birds that had higher levels of average productivity were Chiffchaff (+22%) and Long-tailed tit (+16%) as they tend to be early season nesters. Great Tit (-35%), Song Thrush (-35%) and Garden Warbler (-34%) all did badly with reduced productivity levels with Chaffinch, Blue Tit, Willow Tit, Blackcap, Robin and Dunnock all having reduced productivity levels in the 20%'s.
Constant Effort Site ringing and the Nest Record Scheme will monitor how these birds are faring this year - particularly after the cold snaps of winter.
