The nutcracker

The video explains the symbiotic relationship between Clark's Nutcracker and pine trees in Yellowstone. The Nutcracker eats pine nuts, which are seeds of pine trees. It disperses these seeds by hiding them, aiding in tree growth. The bird's actions help spread seeds over large areas, ensuring new trees grow. This mutual dependence highlights the importance of seed dispersal for both the Nutcracker's survival and the propagation of pine trees.
