Britain's Prince William is more emotional since becoming a father.
The Duke of Cambridge - who welcomed his first child Prince George into the world with his wife Duchess Catherine in July - admits parenthood has changed him and allowed him to develop feelings he's never experienced before.
Speaking to Jane Treays in ITV's documentary 'New Father, New Hope', he said: "I feel a real protective instinct, more so now that I am a father, which is why I get emotional.
"The last few weeks for me have been a very different emotional experience - something I never thought I would feel for myself."
The second-in-line to the throne - who is the patron for the charity Tusk - was reduced to tears after seeing distressing photographs of a slaughtered rhino bleeding to death and insists George's birth has made him re-evaluate how he views the world.
He explained: "I find, even though it's only been a short period, a lot of things affect me now - when I see a clip like that there's so much emotion and so much feeling wrapped up into conservation and environment. It's so powerful.
"The wildlife is incredibly vulnerable and I feel a real protective instinct, more so now that I am a father, which is why I get emotional about it... you want to stand up for what is very vulnerable and needs protecting. Elephants, rhinos and many other animals that are persecuted don't have a voice."
