BROADCASTING legend Sir David Attenborough surprised a schoolboy fan by penning a very personal response to a letter he wrote him.

Toby White, a Year seven pupil at Monmouth School, sent an inquisitive note to the beloved documentary maker, asking him about his favourite creatures to film.

And just six days after it was posted, Sir Attenborough’s carefully crafted response landed on the School’s doorstep.

The eleven year-old sent the letter as part of a class assignment the boys were set by biology teacher Lizzie Davies to write to their favourite scientists.

“It’s very nice Sir Attenborough took the time to reply,” said Toby.

“I asked him what his favourite animal was, which animal he would bring back from extinction and what is the strangest looking animal he’s ever seen.

“He said the strangest animal he knows is the aye-aye, which is my dad’s favourite.

“I was surprised he replied because I never heard back from the last letter I sent to an actor.

“He’s my favourite biologist and zoologist – he’s good at acting and staying safe when he’s making the documentaries.”

Toby said he will treasure the letter and plans to frame it for his bedroom wall.

He added: “I look up to David Attenborough because he doesn’t get too close to the animals and never harms their habitats by destroying their nests – he’s always very respectful."

Sir Attenborough, 89, is one of the UK’s most celebrated national treasures.

Toby’s biology teacher Miss Davies said: “It took just six days for Sir Attenborough’s reply to arrive.

“I hoped he would reply, but I thought Toby would only receive a signed photograph.

“The fact he took the time to respond personally to each of his questions is just amazing.”
