“The birds are Hooded crows Corvus cornix (that's right, not the same species as the Carrion crow C. corone anymore: see Parkin et al. (2003)) [adjacent Hooded crow pic from wikipedia]. What the hell are they doing? It sure looks like they're harassing the cats purely for their own entertainment (I'd like to know if we can rule out other possibilities: are they defending a patch of territory?, for example). Their taunting, teamwork, and ability to pre-empt the cat's moves are all suggestive of a complex intelligence, but you already knew that this was true of crows. Pass me a New Caledonian crow C. moneduloides, I have some woodwork that needs doing. The video is also a nice introductory tutorial to domestic cat body language. Lesson 1: aggression and hostility.”
