A sickening video shows a builder laughing and posing after biting the head off a live pigeon in front of his friends.
The grim clip shows the men, who appear to be on a building site in the UK, taunting the bird, which was roosting in the rafters.
The video, which has been viewed more than 200,000 times since it was posted on Facebook , starts with one of the builders shouting: "Don't let it out that window."
The man in a high-vis vest then says: "I'm not going to let it out the f***ing window, watch. It's coming down to daddy."
He is then seen hitting the ceiling where the bird was roosting with a rod, saying "come to daddy" as the bird falls to the ground.
