Where is the shrine located in the "The Bird in the Mountains" shrine quest in The Legend of Zelda: Breath of the Wild?

The "The Bird in the Mountains" shrine quest in The Legend of Zelda: Breath of the Wild is a shrine quest that leads you to the hidden Tena Ko'sah Shrine. This quest is located in the Tabantha region, specifically near the Rito Village. The quest is given by a Rito named Kass, who can be found playing his accordion on a small hill southwest of Rito Village. Kass will provide you with a riddle that hints at the location of the shrine. The riddle goes like this: "The bird in the mountains, now forgotten by the world, spreads its wings toward the heavens. The grove of its chest is the key to the shrine."

To solve this riddle and find the shrine, you need to understand the clues provided. The "bird in the mountains" refers to the Rito Village itself, which is shaped like a bird. The "grove of its chest" is a specific location on the bird-shaped village that you need to investigate. The shrine is hidden beneath the ground, and you need to perform a specific action to reveal it.

Here are the step-by-step instructions to complete the quest and find the shrine:

1. Start by traveling to Rito Village. You can reach this area by heading northwest from the Central Hyrule region. The village is located on a high plateau, and you can use the nearby Tabantha Tower to glide into the village if you have already activated it.

2. Once in Rito Village, locate Kass. He is usually found on a small hill southwest of the village, playing his accordion. Speak to him to initiate the shrine quest and receive the riddle.

3. After receiving the riddle, head to the center of Rito Village. Look for the large wooden structure that resembles a bird. This is the "bird in the mountains" mentioned in the riddle.

4. The "grove of its chest" refers to the area directly beneath the bird's chest. You will notice a circular platform with a pattern on it. This platform is the key to revealing the shrine.

5. To reveal the shrine, you need to perform a specific action on the platform. Stand on the platform and use a fire-based attack or item to ignite the pattern. This can be done using a fire arrow, a flame weapon, or by dropping a piece of flint and striking it with a metal weapon to create a spark.

6. Once the pattern is ignited, the ground will shake, and the Tena Ko'sah Shrine will rise from beneath the platform. Approach the shrine to enter it and complete the quest.

Important tips and considerations:
- Make sure you have a fire-based item or weapon before attempting to ignite the platform. If you don't have any, you can find flint in various locations throughout the game, or purchase fire arrows from certain merchants.
- Be cautious of the weather. If it is raining, it will be difficult to ignite the platform, as rain extinguishes flames. Wait for clear weather before attempting the quest.
- If you are having trouble finding Kass, listen for the sound of his accordion. He is usually easy to spot due to his distinctive music.

Common mistakes to avoid:
- Do not confuse the "grove of its chest" with other parts of the bird-shaped village. The platform you need to ignite is specifically located beneath the chest area.
- Avoid using ice-based attacks or items, as they will not ignite the platform. Stick to fire-based methods.

Advanced techniques or optimizations:
- If you have the Revali's Gale ability from the Vah Medoh Divine Beast, you can use it to quickly reach the platform from a higher vantage point.
- You can also use the updrafts created by the nearby fires in Rito Village to glide directly to the platform, saving time and stamina.

Required items and preparation:
- A fire-based item or weapon, such as fire arrows, a flameblade, or flint and a metal weapon.
- Optional: Revali's Gale for quicker access to the platform.

Alternative approaches:
- If you do not have any fire-based items, you can use a campfire or a nearby torch to ignite the platform. Simply carry the flame from the campfire or torch to the platform using a wooden weapon or a bundle of wood.

Specific examples and scenarios:
- Imagine you are standing on the platform, and it starts to rain. In this scenario, you should wait for the rain to stop before attempting to ignite the platform. Alternatively, you can use a fire arrow, as it can still ignite the platform even in light rain.
- If you are low on stamina and cannot reach the platform from the ground, use the nearby updrafts to glide to the platform without expending too much stamina.

By following these steps and tips, you will successfully complete "The Bird in the Mountains" shrine quest and uncover the hidden Tena Ko'sah Shrine. This quest not only rewards you with a new shrine to explore but also provides a deeper understanding of the game's environmental puzzles and the importance of paying attention to clues provided by NPCs.
