How do tigers know to bite on the neck or throat for an execution? How do they understand all these tactics like suffocation etc. while hunting for food?

Tigers, like many other big cats, exhibit natural hunting behaviors that are instinctual rather than learned through experience. These behaviors are often hardwired in their genetics and are crucial for their survival in the wild. While they may not consciously think about tactics like biting the neck or throat for an execution, these behaviors are ingrained in their hunting instincts.

Here are a few reasons why big cats, including tigers, may exhibit these behaviors:

1. **Efficiency:** Biting the neck or throat is an efficient and effective way to subdue prey. The neck contains vital structures such as the spinal cord and major blood vessels. By targeting these areas, a predator can quickly incapacitate its prey.

2. **Minimizing risk:** Biting the neck or throat helps minimize the risk of injury to the predator. Going for the throat allows the big cat to subdue its prey swiftly and avoid potential retaliatory strikes from the prey's powerful limbs or horns.

3. **Instinctual knowledge:** Hunting behaviors are often hardwired in the genetics of big cats. They are born with an instinctual understanding of how to catch and kill prey. These behaviors have evolved over generations to optimize the chances of survival and successful hunting.

4. **Observational learning:** While big cats may not have a teacher to show them specific hunting tactics, they can learn from observing their mothers or other adult cats during the early stages of their lives. Young cubs often learn by mimicking the hunting behaviors of their mother.

It's important to note that these behaviors are not learned through conscious thought or reasoning but are deeply rooted in the instincts developed through evolution. Over time, individuals with successful hunting instincts are more likely to survive and pass on their genes, leading to the perpetuation of these behaviors in the species.
