The video shows a black porcupine with sharp quills on its back, climbing up a tree. The porcupine is seen gripping onto the branches with its claws and moving slowly and deliberately. The tree has a rough bark and is leafless, indicating it may be winter or early spring. The porcupine's quills are prominently displayed as it moves, and its small eyes and nose are visible. The background is a clear blue sky, and there are no other animals or people in the video.
