The BBC reports climate change has affected the numbers of about a third of the bird species seen in UK hedgerows and gardens, according to a new study. Research by the British Trust for Ornithology (BTO) has shown an increase in some garden birds like goldcrests as they profit from warmer temperatures. 

But it said increased UK temperatures had had an impact on the decline of birds such as cuckoos and turtle doves. Both species have seen population drops of more than 80% in the past 30 years.
