The whole schtick about 'counts as a raven' is a bit whack, because those terms aren't really hardcore defined. Those are colloquial terms and depending on where you are in the world and who you're talking to, colloquial terms may refer to different species altogether. And when you put different languages into the mix, seemingly equivalent terms may suddenly agglomerate different species.
When you say raven, I as a European, think of the rather huge Corvus corax. But there are other big corvids in other parts of the world, that may qualify for the word.
When I say the equivalent word for raven or crow in my native language (German), it very much depends on the bird knowledge of the person I'm talking to, whether they understand this to mean a specific species or just a general term for all black birds of the Corvidae family. Then some people distinguish ravens and crows, even tough there are 3 species that would qualify as a crow, one of which would be called a rook in English.
That's why scientific names are useful.
That being said: you've got a beautiful picture of a jackdaw there. (Corvus monedula)
Edit: Crap. I just now read the comment thread about "Here's the thing" and feel like I just played into that. Gotta read up about that now.
Yeah as a kid i thought raven were much bigger and had orange beaks. Rather late I learned that ravens are usually just large crows. Personally, I don't care much but at least try to learn and use the proper names of things. At least in German, using Krähe seems to be a safe bet in any case.
