  • Once heard only rarely outside the north Kent marshes, the loud voice of the Cetti's warbler is now delighting a whole new set of listeners, from the isle of Anglesey to the banks of the Humber. The bird has moved 150 kilometres further north within the UK in the last 40 years, in response to the changing climate.

And while Cetti's warbler – a small brown bird that belies its loud song – moved northwards, the Cirl bunting moved south within the UK by 120km, a victim of intensified agriculture.
  • The research team analysed data from a variety of studies, most of them from Europe and North America, finding more than 2,000 examples of how animal and plant species have adapted by moving their habitat.

  • Birds and butterflies may tend to be more mobile, but mammals, reptiles, spiders, insects and all sorts of invertebrates were also tracked.
