This is the moment a hungry woodpecker smashes an expensive wildlife camera disguised to look like a piece of tree bark.
Scientists could only look on helplessly as the wildlife camera, that is triggered to film every time there is movement, was pecked repeatedly by the woodpecker, which left it damaged.
The image of the camera with pieces missing was then shared online after the incident was filmed in the Nizhnesvirsky Nature Reserve, in the Lodeynopolsky District in the Russian federal subject of Leningrad Oblast.
By packing, woodpeckers pierce the bark of the tree, which usually allows them to gain access to insects and larvae.
But the researchers jokingly noted that perhaps the woodpecker was trying to protect the privacy of woodland wildlife.
They said: ‘Vandalism in the reserve! The black woodpecker decided that there should be no interference with the personal life of animals and birds on his site – and destroyed the camera trap.
‘Zhelna [the name of the woodpecker] quickly discovered the camouflaged device, and for several days methodically hit the camera.
‘Researchers who arrived to check the camera trap had to state with regret that it would not be possible to get new frames from this place for a long time.’
The video that the camera managed to record before being badly damaged shows a black woodpecker pecking at the camera, with only its head visible.
They noted that once the camera had been broken, the woodpecker lost interest in it. The researchers could then only watch helplessly as it was destroyed and they had to go and retrieve it.
