Today, Kensington Palace shared a video, in which we can hear Prince George, Princess Charlotte and Prince Louis speak for the first time in public. In the video, which was filmed in the garden of Kensington Palace, the children ask Sir David Attenborough (94) questions about nature. William and Kate’s adorable brood got to know the famous TV broadcaster a few weeks ago on September 24, when he visited the Cambridges at their home in Kensington Palace.

Prince George (7) wanted to know from Sir David Attenborough what animal he thinks would become extinct next. Sir David tells him that he doesn’t hope that any will, but also that we need to do more to protect endangered animals. Princess Charlotte (5) inquired whether Sir David liked spiders like she does to which he replied that he truly does. Prince Louis (2), however, was most adorable asking what animal Sir David likes. The answer is in the video.

Check out the cute trio quizzing one of the most famous TV naturalists in the world.
