This crow thinks he's pretty sneaky. It's hard to say what exactly the crow's motive for wanting to get closer is, and in the case of a crow it could be a lot of things. Crows (and other members for the Corvidae family such as ravens and jackdaws) are the smartest birds on the planet and regularly in the running for being one of the smartest animals in general. It's a good thing that this guy didn't do anything to get on this crow's bad side. In a study in Seattle, scientists wore masks as they abducted several crows around campus and then released them. Anytime a scientist went out wearing that style of mask, he/she was attacked by all the local crows - which means not only did they remember, they also accurately described the mask to all their friends. This knowledge was even passed down over generations, but the crows never attacked anyone wearing any other type of mask.
