Information collected by BTO volunteers shows that numbers of many resident bird species, and some migrants, increased in 2015. However, the spells of cool, wet weather that much of Britain & Ireland experienced in late-spring and summer left many birds struggling to breed, with more northerly populations faring particularly badly. See the Nest Record Scheme and Constant Effort Sites scheme preliminary breeding season report for details.
