Pokédex entries

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

Ruby	TAILLOW courageously stands its ground against foes, however strong they may be. This gutsy POKéMON will remain defiant even after a loss. On the other hand, it cries loudly if it becomes hungry.
Sapphire	TAILLOW is young - it has only just left its nest. As a result, it sometimes becomes lonesome and cries at night. This POKéMON feeds on WURMPLE that live in forests.
Emerald	Although it is small, it is very courageous. It will take on a larger SKARMORY on an equal footing. However, its will weakens if it becomes hungry.
FireRed / LeafGreen / Y	It dislikes cold seasons. They migrate to other lands in search of warmth, flying over 180 miles a day.
Diamond / Pearl / Platinum / Black / White / Black 2 / White 2 / X	It has a gutsy spirit that makes it bravely take on tough foes. It flies in search of warm climates.
HeartGold / SoulSilver	When it gets cold, they migrate, flying over 180 miles a day. It hunts for tasty prey.
Omega Ruby	Taillow courageously stands its ground against foes, however strong they may be. This gutsy Pokémon will remain defiant even after a loss. On the other hand, it cries loudly if it becomes hungry.
Alpha Sapphire	Taillow is young—it has only just left its nest. As a result, it sometimes becomes lonesome and cries at night. This Pokémon feeds on Wurmple that live in forests.

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.
