Winona's Swellow is a shiny Swellow that was the last Pokemon she used during her Gym battle with Ash.
It is unknown when or where Winona got this unusual specimin, but colour wasn't the only special thing about Swellow. It was also a formidable opponent in battle and although its endurance wasn't great it made up for this with its impressive speed and powerful attacks. During her battle with Ash, Winona's Swellow easily defeated Ash's Grovyle and hit his Swellow many times, exhausting the normal coloured Pokemon. However Ash's Swellow eventually defeated it by using Wing Attack on the ground, blinding the shiny Swellow with sand before finishing it with Wing Attack.
Winona's Swellow influenced Ash's Swellow to learn Aerial Ace, having almost defeated it by using this move along with its other attacks.
