{"fact":"Crows display \"mental time travel,\" remembering not just where they cached food but also what type of food it was and when they hid it, allowing them to prioritize retrieving perishable items first.","context":"While the autonoetic character of episodic memory is difficult to approach experimentally, episodic-like memory has been demonstrated in western scrub-jays, corvids that store food items and recover them for consumption, often months later. In recovering food items, they show memory for what food item was cached where and when. This enables the birds to retrieve perishable food earlier, while non-perishable items can be left in storage (Clayton et al., 2003; Clayton & Dickinson, 1998, 1999).","source":"Janina A.
