Google Search of the Week: Return of the Turkey Vulture

Is there some issue I'm unaware of with respect to the anus of a turkey vulture? Some urban legend I'm not in on? Because this is the second time "turkey vulture anus" has landed someone on this site. And it's from a totally different part of the country, thus precluding the likelihood that its some high school kid doing a project on the anatomy of a turkey vulture.

Anyone? Anyone? Bueller?
