Various forms of cooperation, for example food and information sharing, are frequently observed in corvids, and they can engage in exchange interactions with human experimenters and accept delayed rewards. Here, we tested whether crows and common ravens would reciprocally exchange tokens with a conspecific in an exchange task. Birds received a set of three different types of tokens, some valuable for themselves, that is, they could exchange them for a food reward with a human experimenter, some
