Trying to remember 1970's film with Bighorn Sheep clashing horns and other wildlife in Mountains?

Think it was a Disney Sunday Movie. My hubby and I remember it was played on television once a year, came out in the the theaters in the early 70's, could have been a documentary. Thought it was ';Call of the Wild';, but as it turned out, it's not. DH remembers it playing on the theater at the same time as ';Song of the South.'; Can you help???Trying to remember 1970's film with Bighorn Sheep clashing horns and other wildlife in Mountains?
It may be ';The Vanishing Prairie'; which is part of the Walt Disney Legacy Collection - True Life Adventures, Vol. 2 (1953). It originally aired in 1954, winning an Oscar to boot! Check out the details here on the Amazon link. Make sure to scroll down and read the second user review on this one, as it specifically mentions the bighorn sheep and other mountain animals.
