According to Wikipedia:
Recent research has suggested that Western Scrub Jays, along with several other corvids, are among the most intelligent of animals. The brain-to-body mass ratio of adult Scrub Jays rivals that of chimpanzees and cetaceans, and is dwarfed only by that of humans. Scrub Jays are also the only non-primate shown to plan ahead for the future, which was previously thought of as a uniquely human trait. Other studies have shown that they can remember locations of over 200 food caches, as well as the food item in each cache and its rate of decay. Western scrub jays also summon others to screech over the body of a dead jay, according to new research from the University of California, Davis. The birds’ cacophonous “funerals” can last for up to half an hour.

The jay has quite the look, wondering perhaps where to put the pile of ‘tapioca pudding’; and how long it will keep…

Yeah, and my dog sometimes has difficulty discovering that there IS food in her bowl, and it is to be found in the same place it was yesterday, and the day before, and the day before. Once she finds it though, there’s no need figuring out how long it will keep.
