An Etymological Dictionary of the German Language/Annotated/Krähe
Krähe, feminine, ‘crow,’ from the equivalent Middle High German krœ̂e (rare), feminine (usually krâ and krâwe, feminine), Old High German chrâia, chrâwa, and chrâ, feminine; compare Dutch kraai, Old Saxon krâia, feminine, Anglo-Saxon crâwe, feminine, English crow; a West Teutonic word allied to krähen, which was originally a strong verb. The Scandinavian term kráka, feminine, ‘crow,’ cannot be immediately connected with the cognates adduced; it is only very remotely allied.
