Although they are more visually distinct and don’t overlap geographically, American crows are more closely related to the collard crows of China, or the carrion crows of Europe, than they are to common ravens. I don’t know if crows see our vocalizations as an attempt at communication, but they might see it as step one in a series of steps that ends with them being fed- they are vocalizing back to the person because the last time they tried, the person fed them afterwards. While that’s certainly cool in and of itself, what makes it interesting from the perspective of their calls is that although their alarm call in this instance does not sound different to me, they almost never draw the crowds the initial stimulus day does. Do crows try and get the attention of their human feeders with sounds?
