Launch of State of Nature report 2016

The State of Nature partnership officially launches their second report (State of Nature 2016) at the Royal Society in London today, 14 September 2016. Produced by a consortium of 53 diverse conservation organisations, this report provides a snapshot of the population status of almost 4,000 terrestrial, freshwater and marine species and updates the statistics in the previous and first State of Nature report in 2013. The BTO is a key player, not only contributing the population trends for most birds, but also those for some mammals and a number of widespread butterflies. For a personal take on today's report by one of its authors, read more.

Our satellite tagged Cuckoos are well on their way to their wintering grounds. Seven birds have already successfully crossed the Sahara, whilst another four are poised to do the same during the next few days.
