So, many animals have developed ways to store food for later. They find extra food and save it for times when less food is available.This process of storing food for later is known as hoarding. But, not all the hoarding is the same.

Different animal species use different hoarding strategies,depending on their abilities. So let's look at two different hoarding strategies and why different animals may use them.

So, they may use another hoarding strategy dispersing the food, um...dividing it up and hiding it in many different locations. With this dispersal strategy, even if other animals find some of the food, they are unlikely to find all of it. For this strategy to work, the animal must have a good memory.

In the lecture, the professor mainly talks about two different hoarding strategies for animals. The first kind of animals may hoard the food in one location and this strategy can work for animals that are competent to defend the food supply. For example, a kind of squirrels that eat the seeds in Pine Cones will store a big amount of pine cones under a tree.And they are aggressive and good at chasing other animals away when they try to steal their food. The second strategy for animals that are not able to defend the stored food is to disperse it and hide it in many different locations. Because the competitors are unlikely to find all of it.
