For all we know they are in but they're lying by saying they aren't and they're really hidden in secret places.
Articuno at the top point of Alaska or in Antarctica, Moltres in the circle of fire or Hawaii, Zapdos appears near nuclear power plants but only during massive thunderstorms... 
Mewtwo of course is located on the moon, so good fucking luck with that.

Articuno is canonically northern, I believe. But I think they stated that title would catch legends in events, like the games. Mew would be on the moon, Mewtwo on an abandoned island where an experimental failure took place, preferably with a mansion.
