This deer looked a bit of a fool when he picked a fight with a plastic model he thought was a real-life rival.
The animal attacked after spotting the fake deer apparently trespassing on its territory.
I'll show you! The buck goes on to the attack as its rival stands its ground
This extraordinary set of pictures, taken by photographer Don Jones, show how the buck fronts up the plastic model.
When the model shows no sign of stepping down, the deer launches at it with his impressive antlers.
He doesn't back down until his rival has been floored - but appears quite bemused when its head pops off.
One last push: The fake deer apparently trespassing on its territory, is overturned
The bizarre spectacle was captured in the Kootenai National Forest in Northwest Montana, America.
Mr Jones snapped the pictures after setting up the 'decoy' deer in the area to see what reaction it would get from the resident bucks.
The 52-year-old, from Troy in Montana, said: 'I knew that once the bucks saw this smaller decoy buck they would not stand for it.
Finished: The plastic model lies in bits, its head knocked off
