For species to reproduce and survive, they depend on the acquisition of energy. The optimal foraging theory is focused on explaining the feeding strategies among carnivores and herbivores. Foraging involves actions that are related to the acquisition of food by the species, and these behaviors are critical in the evolutionary and ecological feedbacks between the species and their environments (Sovie et al., 2019). For instance, the theory is concerned about how an individual could maximize the intake of energy through foraging while minimizing expenditure to determine where, when, and how long to forage. There are other species of animals cache food, including several birds and other small mammals. People exhibit several caching behaviors, securing food quantities to use in the future and hoarding unnecessary objects. The caching presence in the animal kingdom indicates many species have adapted the behavior as a strategy (Newbury & Hodges, 2018). Squirrels require essential resources for many urban animals as their populations change with the same predators and environmental conditions. Fox Squirrel, as many animals in the wild, changes their behavior patterns with the seasons. Similarly, the eastern grey squirrel (Sciurus carolinensis) shows the scatter-hoarding behavior, keeping food in small hoards underground. This study reviews various researches conducted over the years on the foraging and storing behavior of the Fox Squirrel compared to the Eastern Gray Squirrel (Sciurus carolinensis). Fox squirrels are a group of North American tree squirrels that are the largest and most ground-dwelling, which have raised conservation concerns due to their declining population. These squirrels act as crucial agents of dispersal for hypogeous fungi. Eastern gray squirrels, on the other hand, use forested habitats by relying on similar resources such as fox squirrels (Newbury & Hodges, 2018). The interaction of these two categories of squirrels was limited because of the partitioning of habitat. As the interaction between the two species changes, it causes an opportunity to examine the predation effects of sublethal since it relates to the risk of a perception of species and habitat structure (Amspacher et al., 2019). Unlike eastern gray squirrels, fox squirrels are found in areas where the predator densities are higher. This shows that the vigilance is increased for fox squirrels as an adaptation behavior. Thus, the foraging and food storing decisions are made by the squirrels in line with minimizing the risk of predation in their habitat. This is because, with caching, squirrels are able to survive when there is scarcity and helps reduce the foraging time in the future while searching for food that may expose them to risks. Significant research of scatter-hoarding among tree squirrels has focused on the gray and fox squirrels because of the similar morphology and behavior, especially in handling and bury food. Both the squirrels do little to no hibernation and have to intensely cache during fall masting to have what is considered enough food to continue surviving even in winter, which goes for almost nine months (Haverland & Veech, 2017). Thus, these two types of tree squirrels make economic investments in a short period and amidst social competition, which affects their survival and reproduction fitness over an extended term. They tailor their cache investment that includes the amount of
