King Charles appears in a surprise birthday tribute for Sir David Attenborough, marking the naturalist’s 100th birthday. Across a short film released by Buckingham Palace, the king is shown writing a handwritten congratulatory message at Balmoral Castle. The tribute is presented as a whimsical delivery, with animals acting as “creature couriers” to carry the centenary card from Balmoral to London. In the video, Charles wears an animal-themed tie featuring elephants and reflects on his long friendship with Attenborough, spanning more than 60 years.

Multiple outlets describe the same concept: wildlife is used in the film to deliver the card as part of the celebration. BBC News reports the message is delivered with help from the king’s “friends” in a video released by Buckingham Palace. The Independent and The Guardian similarly focus on the “special delivery” format, where the king’s tribute and the card handover are framed around a relay involving animals.
