Abstract: Although numerous birds have been found impaled on barbed wire fences, a female Northern Harrier (Circus cyaneus) impaled on a fence at Vancouver International Airport in 2005 appears to be only the third documented case of such impalement for that species and the fourth for any harrier species in spite of their habit of frequently flying back and forth just above such fences.
