Galarian Forms of Legendary Birds

These must be the Galarian Forms of Legendary Bird Pokémon. 

This is a Galarian Articuno, 

the Psychic and Flying Type, 

This is a Galarian Zapdos, 

the Fighting and Flying Type, 

And this is a Galarian Moltres, 

The Dark and Flying Type. 

I think a Galarian Articuno was different than 

a regular Articuno the Ice and Flying Type, 

a Galarian Zapdos was different than 

a regular Zapdos the Electric and Flying Type, 

and a Galarian Moltres was different than 

a regular Moltres the Fire and Flying Type.
