Abstract: While the studies described so far often involve animals learning something about foraging environment, they were not designed as studies on foraging and learning per se(in itself). To even touch on the tip of the iceberg of studies done on learning and animal foraging would require a series of books. After all, these sorts of studies have been a mainstay in psychology over the last fifty years, and there have been thousands of studies examining learning in the context of foraging . Here we shall look at a tiny but important subsection of the work on the foraging and learning by focusing on:①brain size effects on the foraging and learning; ②learning and planning for the future; ③hippocampal size and caching ability; ④evolution and phylogeny of food caching.

Key words: food caching, planning for future, hippocampus, foraging, , phylogen
