"Whoa! B-birds? TINY birds?! Wh-what... ARE they?!"

— Groose

Chirris are creatures from The Legend of Zelda: Skyward Sword. A species of small birds native to the Faron Woods, they are desired for their plumage, which may be used as a material for upgrading items, or sold for profit. In order to obtain such a feather, Link must sneak up on Chirris congregating on the ground, and catch one in his Bug Net. Blue Chirris are the rarest variety of their kind, and when caught, yield Blue Bird Feathers. When Groose first lands in the Sealed Grounds, he is initially scared of the Chirris due to their unfamiliar appearance and size.
