This guide will let you know how to catch a Legendary Galarian Articuno in Pokemon Crown Tundra. Go through the guide and follow the step-by-step instructions to catch the pokemon.
You can find this in Crown Tundra Map near the Snowslide Slope, as shown in the image below.
When you get there, you have to aggro the Articuno, and it will fly to the top of the mountain, so you have to follow him till he stops. It will split into three versions of itself when you get closer to it, and they will start rotating.
You will need to spot the real one from them and follow him. To spot the real one, you have to look carefully at the one who lifts his wing in the air while others don’t, as shown in the image below.
When they stop rotating and come back on the ground, you have to get closer to the real one and fly to the sky. He will attack you after coming back, triggering a fight. Then you have to defeat and catch him.
