Another Funny English Headline

Today my husband set aside a page from our local newspaper because of a very funny headline. This one got by the editor(s), but there must have been numerous readers who called in about the error in word choice/word form.  The headline in the paper edition was

"Day Two of Furious Turkey Demonstrations" 

I looked for the link online before photographing the newspaper.  The online edition had been correct(ed) as you can see here.  

Do non-native speakers understand why the original headline is so hilarious or strange?  Do you know the bird "turkey," which Americans eat at Thanksgiving?  This headline seems to be announcing that turkeys are furious and demonstrating for the second day.  I wonder if UT San Diego will make a formal apology since the above use of English error makes the reader start off laughing about something serious.
