Crows are highly territorial in my experience and will 'have a go' at other birds if the opportunity arises. There's no doubt - I have seen them in action here in the UK locally. Gangs of crows regularly hassle young buzzards, perhaps not injuring them but letting them know who is boss!
A little owl that set up nest in an old oak close to a family of crows was definitely knobbled - we saw that for ourselves - one evening back in April.
