Just a bear trying to leave a mark on this all too wild world! 🐻 Bears use rub trees to communicate with each other, assert dominance, or establish territory. By leaving their scent or hair behind, they can make their presence known: BEAR WAS HERE ❤️ NPS Video: A brown bear at @glacierbaynps exuberantly rubbing its back against a forest tree, pausing at one point to look around, before continuing his back scratching. The tree's bark is disturbed, indicating that this tree has served as a marker for scores of animals over the years. #mondaymood #bear #sway #itch #glacierbaynationalpark #greatoutdoors
