Picked my nose, nobody even knows ...
Candid portrait of an old bison (Bison bison) cleaning its nose.
Bison often stick their long, rough tongues into their nostrils to clean them out. They use the tongue like a built-in wipe to remove mucus, dust, dirt, and insects that accumulate in their nasal passages, especially in dry, dusty prairie environments.
This behavior also helps keep their noses moist, preventing the sensitive nasal tissues from drying out and cracking, which maintains their excellent sense of smell for detecting predators, food, or mates.
In some cases, it’s part of the flehmen response, where they curl their lip and use the tongue/nose contact to better analyze scents and pheromones in the air. Overall, it’s a practical grooming habit that supports their survival in harsh conditions.
