Prince George may only be five years old, but he's already accomplished a longstanding royal tradition.

Prince William, Kate Middleton and their three children tagged along with Queen Elizabeth II to the Balmoral Castle in Scotland for the royal family's inaugural grouse hunt this past weekend.  

According to royal reporter Emily Andrews, George was accompanied by his mother Kate Middleton to the shoot lunch and was later joined by his extended family, including Prince Charles, Prince Edward, Sophie Wessex, Zara and Mike Tindall, and second cousins Lady Louise Windsor and James Viscount Severn.

Her Majesty also made an appearance when she drove up in her range rover.

"It was a very jolly family lunch. The men and Princess Anne all shoot in the morning, then the wives and children join the party for the shoot lunch on the moor," a source told The Sun.

However, when the public caught wind that the future King attended the annual event, they took to Twitter to voice their frustration over the longstanding tradition.

Not a fan of these so-called traditions. Didn't William visit a sanctuary in India and vowed to continue his crusade to protect Wildlife 🤷🏻"â™€ï¸. You can't have it both ways my dear William.

It's just too bad animals have to die in order for them to have fun. That's a terrible thing to teach children, especially at George's age. Modernize Royals. Join the human race.

It may be "˜tradition' but I really wish they would get called out more for these shootings. It's horrible and has no place today.

Absolutely disgusting! The 'royal' family should be setting an example, rather than slaughtering innocent birds - horrendous,  but so typically British!

Although this isn't the first time the British monarchy has been criticized for their annual participation in the grouse hunt, it doesn't look like they'll be canceling the event anytime soon.

Prince William was seen participating in the hunt at only 12 years old, where he shot his first bird in only a single shot.

However, that doesn't mean every member of the royal family made an appearance.

Prior to their marriage, Meghan Markle convinced the Prince Harry to give up the sport, and the Duke and Duchess of Sussex weren't seen at the grouse hunt, despite accompanying their relatives to Scotland.

"The Boxing Day shoot was always going to be a tricky issue," a royal insider told the Daily Mail. "Meghan is a keen animal rights campaigner and doesn't like hunting in any form."

"Harry loves it and has always been out there on Boxing Day. But if it means breaking with long-standing royal traditions to avoid upsetting her, so be it. It's fair to say that there are some pretty stunned faces around here."
