Sir David Attenborough turns 90
Sir David Attenborough - who turns 90 on Sunday - has been hailed as "a god of wildlife presenters".
As the naturalist enters his tenth decade, the presenters of Springwatch have described Sir David as a beloved inspiration.
"I think when you think of wildlife programmes and presenters, he's God, isn't he?", Springwatch presenter Michaela Strachan said.
"He's up there and we are all really proud of him and have all been inspired by him.
"And he is unbelievably intelligent, not just on wildlife but on many other subjects as well.
"I don't know anybody that doesn't like David Attenborough. I know lots of people that don't like us but everyone loves him".
Sir David joined the BBC after serving in the Royal Navy from 1947 to 1949.
He was initially discouraged from appearing on screen because his bosses thought his teeth were too big but he launched his Zoo Quest series in 1954.
Sir David has since fronted a string of series including Life On Earth, The Living Planet, The Trials Of Life, The Blue Planet and Planet Earth.
