This is the moment two bears were caught grappling with each other in remarkable photographs taken in a national park.
Mark Buckler, 54, captured the pair of bears mid-scrap showing off their best wrestling moves.
The brown bears were caught fighting in Katmai National Park, Alaska, US.
Standing up in a playful tussle, some of the snaps show the bears stood on two paws and grappling with each other.
Other photographs captured the pair tumbling on the ground, wrapping their limbs around each other in a scuffle.

Brown bears are some of the biggest carnivores alive and can communicate with one another by scratching on trees, according to WWF.
There is an estimated population of 2,200 brown bears at Katmai National Park and hikers often see them when in the area.
The park was established in 1918 in an effort to preserve the area and is now an important habitat for salmon and brown bears.
Mark, from North Carolina, said: ‘These bears are simply playing, possibly for just fun or recreation.
‘Play behaviour in many animals, especially younger animals, helps prepare them to gain some of the skills necessary for survival.’
