A six-year-old boy from Pembrokeshire has put pen to paper to mark Sir David Attenborough's milestone 100th birthday, by drawing 100 of his favourite animals.

Max Evans-Browning from Neyland, carefully selected and hand drew 99 of the broadcasting legend’s favourite animals, for every year of his life.

To complete the collection, Max has now drawn a platysaurus attenboroughi, also known as Attenborough's flat lizard, which was named after the renowned biologist.

Sir David is not just a national treasure, but a global icon, who celebrates his 100th birthday on May 8.

Max has been a fan of Sir David for as long as he can remember, who would watch his documentaries every night before bed as a toddler.

"When I saw last year he was going to be 99, I said 'why don't we do 99 for him?' And then we did it and it went everywhere and then finally got to him and a message came back," said Max.

"So this year, because he's 100, I wanted to add one more on."

The 100th drawing took Max "all night" - his mum Samantha said.

The drawings sketched for Attenborough's 99th birthday last year spanned across eight A3 sheets of paper and took Max four days to complete.

Global recognition of Max's adoration began when his mum posted his drawings on Facebook. The post attracted hundreds of shares and caught the attention of Sir David himself.

Samantha said Max has watched all of Sir David's documentaries and owns more animal encyclopedias than she can keep track of!

With the pair still on cloud nine after receiving a hand-written letter from Sir David's previous birthday, Max has written another for his 100th, signing it off with a safety warning, stating: "I hope you have the best birthday and be careful blowing out 100 candles on your cake."
