For Royals, bird hunting may be a centuries old royal tradition but for PETA, the People for the Ethical Treatment of Animals it is not.

PETA has reportedly sent a letter to Kate Middleton, the Duchess of Cambridge, to put an end to her husband Prince William's hobby of bird hunting.

The multiple reports which said that Prince William, the Duke of Cambridge bought 250 pheasants, ducks, and partridges to celebrate younger brother Prince Harry's 27th birthday prompted PETA to send letter to Kate requesting to stop her hubby’s bird hunting hobby.

We understand that Prince William has given a gift of 'game birds' to Prince Harry for his birthday. There is no honour in buying birds and reducing them, as if they were clay pigeons, to shooting targets. Those who aren't killed outright are often dispatched by having their necks wrung, which does not cause an instant or painless death, PETA President Ingrid Newkirk wrote letter to Kate.

May I ask you to use your influence on the Princes and ask them to reconsider this gift? You are in a unique position to be able to wield considerable influence over whether people everywhere view animals and their place in the world with kindness or blithely ignore their suffering. Please ask the princes to open their hearts to the suffering of birds casually used as skeet and make the compassionate decision not to kill for fun. By cancelling the planned 'day's sport' in favour of a more enlightened, fitting and humane pursuit, they will win hearts and commendations and spare hundreds of birds a terrifying end, making it clear that the monarchy is in tune with the social movement against cruelty to animals.

Newkirk also influenced Kate Middleton by saying that the monarch might suffer some public objection if the bird shooting is continued.

The Buckingham Palace representatives were not available for the comments.
