This page explains how to start and complete the Recital at Warbler's Nest shrine quest.
How to Start the Quest
Before you can start this quest, you have to complete the Divine Beast Vah Medoh dungeon first. Then talk to Kheel at Rito Village to start the quest.
How to Complete the Quest
Teleport to Akh Va'quot Shrine in Rito Village, then you can optionally talk to Amali near the shrine if you haven't already, to complete the quest Find Kheel.
Kheel said her sisters are all in Rito Village, and she said Genli is in the kitchen asking for salmon meunière. First, from the shrine, go downward on the walkway in the village until you find a hut with a cookpot in it. Go into the hut and talk to Genli. She mentions the Slippery Falcon, which is the item shop in the village.
Make your way farther down the walkway until you find the item shop. Talk to Cree, the young girl in the item shop, and she gives you Goat Butter, one of the ingredients for salmon meunière. She also mentions that her sister Notts is practicing her songs up high, and Kotts went to catch hearty salmon and is probably at the pond near the entrance to the village.
Go downward along the walkway until you reach the bottom, and follow the path down all the wooden stairs and bridges until you find Kotts in a pond on the left. Talk to her to get hearty salmon, another ingredient for salmon meunière.
Then teleport back to the shrine in the village, and look upward at the village to see some musical notes floating up from one of the rock ledges on the southeast part of the rock spire that the village is built around. You can climb or use Revali's Gale to reach that ledge. When you get there, talk to Notts to get Tabantha wheat, another ingredient for salmon meunière.
Then go back down to the hut where Genli is standing next to the cookpot, hold a Tabantha Wheat, Goat Butter, and Hearty Salmon, and cook them in the cookpot to get Salmon Meunière. Then talk to Genli and give her the food.
Now go back to the Warbler's Nest and talk to one of the girls. They will sing in the following order: . Stand on the shrine platform, and look around at the stones with holes in them. Each stone has a certain number of short stones sticking up out of the top. If you don't have a Korok Leaf, go northwest and chop down trees until you get one. Then stand on the shrine platform, and use the Korok Leaf to blow air through the holes in the stones, in the order that the girls sang in (see above). This will make Voo Lota Shrine appear.
