I never forget a face...

The question here is, are there other crows at the North Pole?

Crows are common in the northern hemisphere, and I defy you to distinguish one from another. However, if there is only one, and you have a grudge against a particular one, I defy you to explain how that one is maybe, probably, not the one you have a grudge against.

I find it far more unlikely that he will assume a random, singular crow is not the one he hates.
