These dramatic images show the moment a bitter feud erupted between a group of red squirrels.
Captured by 27-year-old Julian Rad, photographer in Austria, the pictures show a group of squirrels fighting with one another.
He said: “There was so much action going on, it seemed like I was in the middle of an action movie, there was dust whirling everywhere and I could hear them squeak.”
The images show the squirrels attacking one another through the air, claws held out.
Julian said that the squirrels live close to each other.
He said: “Normally they are friendly to each other but sometimes it comes to territorial fights when two territories of two individuals overlap.
“I have never seen images of fighting European ground squirrels and I am proud to be the only one or one of only few photographers who could caption such behaviour and I can call myself lucky for having witnessed and captured such a rare moment.”
