What each game says about it, in the games' own words.

Black	These bird Pokémon are excellent divers. They swim around in the water eating their favorite food--peat moss.
White / X / Omega Ruby	When attacked, it uses its feathers to splash water, escaping under cover of the spray.
Black 2 / White 2 / Y / Alpha Sapphire	They are better at swimming than flying, and they happily eat their favorite food, peat moss, as they dive underwater.

Official data here is present-day reference data from PokéAPI, not a snapshot of any one game's era — the Fairy type and hidden abilities arrived partway through the series, so a difference against an older game can belong to the series rather than to that ROM hack.
