How do you catch legendary bird trio in X/Y?

Question

So I looked it up on the site & yeah yeah it talks about the starter & bird relation but it doesn't talk about how to actually catch please type out answer & only use links for siting at the end.

Answer 1

Encounter your respective legendary bird ten times by following it as well as tracking it via your map. After encountering it 10x, visit Sea Spirit's Den in the cave portion to finally capture it.

It appears on random routes after the player beats the Pokémon League and cannot be battled, but once it is found ten times, it retreats to the Sea Spirit's Den where it can be battled.

Please note that the birds vary based on your starter.

Articuno=Chespin
Zapdos=Fennekin
Moltres=Froakie
