He explains that Divine Beast Vah Medoh has become hostile and is terrorizing the skies above the village. Make your way there and climbing the ascending platforms until you find Kaneli, the Rito elder. They're present and accounted for in Breath of the Wild as well, and keep a village in the northwest quadrant of your map.
The Rito are an avian race introduced in 2011's Skyward Sword. Not only will Ganon assume fewer forms at the end of the game, you'll have plenty of opportunities to amass a staggering supply of weapons. Taking down Divine Beast Vah Medoh is no small feat, but you're better off getting it over with now. There's a price to pay for cutting in line, however: you'll have to fight Ganon in his four Divine Beast forms before you challenge his final form, to make up for skipping the game's four main dungeons. Zelda: Breath of the Wild grants you the freedom to go right from the Shrine of Awakening to Hyrule Castle and a final showdown with Ganon, even in your skivvies.
