You can help Wiktionary by providing a proper etymology. Strix, when used for the genus of owls, is a reference to the ancient Strix featured in ancient Greek and Roman legends. The term was used both for the bird itself, and for a monster resembling an owl that would suck the blood of children and was an ill omen. The word was first featured in Boios' Ornithologia and later in Plautus' Pseudolus. Citation: http://muse.jhu.edu/article/257998 I'm not sure how to format this as a proper citation below.
