• THANK you for the good story about the changes to the bird life on Hampstead Heath due to rising temperatures as observed by bird expert Peter Mantle; the weather certainly didn’t feel mild enough for warblers this Monday walking on Hampstead Heath in snow flurries (Quelle surprise! Cold weather at the beginning of February).

I agree with Mr Mantle that the weather has changed, so has the wildlife and plant life. I appreciate his and views and look forward to his book.
