Found this video clip of a rooster. It may be either a new Chinese siren in development. Or is this a JDI spy video?
We can't use sirens in IL. At one point I wanted to teach my SAR dog wail and yelp (howl and bark) on command when running calls through downtown.
The roo-Q-ster is a much better idea. Bonus feature, if the "siren" accidentally falls off while responding, you can always make fried chicken.
