Climate is altering UK bird habits
A number of UK bird species are laying eggs significantly earlier than they were 40 years ago, a report reveals.
A conservation coalition's report says some finches, robins and tits are all laying earlier and puts this down to warming caused by climate change.
Overall, numbers of farmland birds remain about half of what they were in the 1970s, while wintering populations of water birds have risen considerably.
The RSPB said birds were having to respond to climate change to survive.
