I met with Jennifer Ackerman when she was in Australia promoting the book - hanging out at gatherings with my birder friends. We talked about the section (hopefully I am remembering correctly) about chickadees and the way they cache food. Jennifer was likening it to them using a memory palace because of the way the retrieve them not by the order they were buried but by first retrieving the ones which will rot first.
When you read it, deeptravel, you might like to correct my recollection, and / or offer an opinion on whether birds use memory palaces. Or I could check the copy I have of the book. Shall do if necessary.
