Hippocampal volume does not correlate with food-hoarding rates in the Black-capped Chickadee (Poecile atricapillus) and Willow Tit (Parus montanus)
Food-hoarding birds use memory to relocate caches, and species that store thousands of scattered food items must have an extraordinary memory capacity to be able to relocate them. Because the hippocampus is important in the functioning of spatial memory, it is logical to assume that the amount of food stored should correlate with hippocampal volume. Previously, food-hoarding capacity has been used
