Thanks so much Denise and for your generosity! The buffalo are normally quite peacefully unless there is a baby calf in their midst. They are very protective then or if anyone invades their territory.
The sepia could have been taken in the olden days when the buffalo freely roamed the plains before they were senseless slaughtered at a terrible rate.
Tha calf stays an orange color for awhile. This is part of the same herd.
