Crow-killing owl model

Darren Naish at Tetrapod Zoology cites a paper's title:

Incidentally, I'm greatly intrigued by the title of Conover's paper: 'Protecting vegetables from crows using an animated crow-killing owl model'. Sadly I haven't seen this paper.

I'm also intrigued: surely there's a missing hyphen? Or is this more sinister, more deadly, more ... lasery, perhaps, than the kind of model that just flaps its wings and turns its head every so often? 'Cause crows do get used to those pretty fast...

update: Darren has obtained pictures!
