I'm not a contributor but I do see some of these are different in Japanese. I thought some of the English titles where a bit different from the Japanese one on purpose (like that what they used in the English version of that media). Sorry.
Correct term is "Hell Crow". Nowhere do they use the term raven (ワタリガラス) only the term for crow when referring to Reiuji Utsuho. This is an unfortunate mistake perpetuated by a 'touhou wiki' contributor, but has no basis in Touhou canon.
