When an animal is shot but not entirely dead, it often leaves a blood trail as it moves away from the scene. This blood trail can be instrumental for hunters in tracking the animal to where it ultimately succumbs to its injuries. Blood trails can indicate the severity of the wound and help hunters assess their position and the direction in which the animal is heading. Following a blood trail requires knowledge and skill, as tracking an injured animal may lead to a successful retrieval if the trail is carefully followed.
The other options present less likely scenarios. While some animals may recover from injuries, this is not guaranteed and typically depends on the nature of the injury and the animal's health. An injured animal might become unpredictable due to fear and pain, which could affect how it behaves, making tracking more uncertain. Lastly, many animals do not hold still to die, as instinct usually drives them to seek refuge or escape when wounded. Instead, they may show various behaviors influenced by their condition and environmental factors.
