This bird is a Chirri. Although very
Chirri is a type of bird that appears on the Surface in Skyward Sword. They are notably much smaller than Loftwings and cannot be found in The Sky. Link can use the Bug Catching Net to capture Chirris and obtain their feathers. They come in many different colors, the most common being red and yellow, although blue varieties exist as well. These Blue Chirris are much rarer, and they will yield Blue Bird Feathers instead of the normal kind, which have different uses. The birds are usually found in different areas of the Faron Woods, such as the Sealed Grounds and Deep Woods. Some can also be found in Skyview Spring.
