Wild Turkey in Metropolis?

As I took a stroll on my lunch break through Battery Park and on my way back to the office, I see a turkey. No tags on it. No signs saying "Beware of Turkey" or the like. The only wild turkey I expected to see in Battery Park was an empty bottle of the product of the same name. Moreover, it has been frequenting those grounds since approximately November of 2003! The bird's name is Zelda. I knew New York was a diverse place, but this is ridiculous. Thanks to Krystl for the image (taken May 04, 2005).
