Incredible images by a British holidaymaker show the moment a 595-pound Grizzly bear took on a pack of wolves as they munched down on a deer carcass.
The spectacular action shots show the pack of wolves enjoying their prey until they are interrupted by a six-and-a-half-foot long bear. To protect their dinner, the brave wolves attempted to warn off the bear but one by one were swatted away by the bear's giant paws.
One close-up picture shows one wolf baring its teeth on the blood-stained snow as the bear continues to fight. Other photos show the lone bear enjoying a deer supper after scaring off its rivals.
The amazing photographs were taken by Logistics Consultant, Tom Littlejohns, 75, from Guildford on a visit to the Crazy Mountains in the Rocky Mountains, Montana. To take the spectacular shots, Tom used a Canon EOS 1D Mark 4 camera.
"In these particular images, I saw the change from relatively docile and almost large cuddly wolves become unbelievably ferocious both with each other and prepared to take on a fully grown Grizzly," said Tom.
"The environment was very hostile, hungry wolves and aggressive Grizzlies are to be treated with serious respect.
"There were five of us plus I recall three guides armed with a kind of cattle prod in case the Grizzly became too friendly.
"Interestingly enough the wildlife, as is often the case, took little interest in us humans although I'm quite sure the wolves were aware because most of the time they kept the carcass between them and us."
It is estimated that there are around 1,800 Grizzly bears in North America with those that live in the Rocky Mountains spending most of their time in dens.
"Shooting wildlife is a passion, I think you have to be a little light in the head to put up with all the inconveniences it brings," added Tom.
"The results make it worthwhile and I predominantly shoot for what I want and what I see.
"There is an amazing world out there and it will still be there in one-hundred-years and then another one-hundred-years, there is so much to see and experience and I have been so fortunate in being able to see and photograph so much wildlife in its environment.
"When I'm photographing it's that species that I see and at that moment and it's my favourite.
"People are amazed sometimes at the photographs but I see it as the result of technical development by Canon and how lucky I have been to have the opportunities."
