Corvids have a basic grasp of the theory of mind - the ones who hide their food will remember who saw them bury it, and will come back to stash it elsewhere when they know they’re no longer watched. They are vaguely aware that others are also capable of thinking and planning, and anticipate that another bird would seize the treasure later, if ever given the opportunity.

Many corvids also mate for life. They have foods they prefer more than others, and it has been discovered that they can also know and remember their partner’s favourites, and bring those treats to each other, even if they personally don’t care for this food source.

Is that love? A crow cannot be forced to do something it does not want to do, they do as they please and it pleases them to bring gifts to their partners. What is love but joy that stems from the joy of another?

Do they know what love is? A jackdaw knows that another jackdaw it can see has seen it in return - do they know that a spouse that brings them treats does it as a treat to themselves as well?

Do these birds know what love is? Do they know that they love, and are loved in return?
