The line between a sophisticated toy and simple automaton is not a clear one. My thinking is that it boils down to the target market. If it was for adults (and costly) it is probably an automaton. If it is for kids (and inexpensive) it is a mechanical toy. The turkey in the video is much like one currently for sale on ebay. It may have crossed this imaginary divide of mine.
From the eBay description:
Made in germany by Kohler. Wind-up lithographed Turkey circa 1950, blue leg version. The best I've seen in years...works very well. Key is included. Walks very deliberately forward while legs articulate as if strutting along, while plumage spreads out & raises up. Nothing missing, very excellent condition. Very few produced, no loose wheels or bent shafts or broken or loose tabs. 7" long.
I am guessing it started out as a fairly inexpensive toy for children.My visits to antique stores have shown that these tin toys are no longer inexpensive -- especially if they work and are in nice condition. I doubt many kids are spending hundreds of dollars on these antiques. By my definition above, this might suggest that it started life as a toy that has, over the years, become an automaton because it is now collected by adults. There is probably a flaw in this logic, but it's an interesting notion at least.
Here is where you can see more nice photographs of this German made wind-up turkey in toy.
