Every fall, black-capped chickadees will cover an enormous territory gathering seeds and storing them in hundreds of hiding places in preparation for winter. Thanks to an incredible spatial memory, these birds will make their way back to each of their caches throughout the winter to feed, but what is happening inside their bodies to enhance this survival skill is even more amazing. The bird’s hippocampus, the part of the brain that is responsible for organization and memory, actually expands in volume by 30% by adding new nerve cells. Once spring arrives and memory is needed less, the hippocampus reverts back to its normal size.
