Hibird

This bird used to be one of Birds' birds. After Hibari taught him the anthem of Namimori Middle School, the bird became attached to Hibari, often sitting on his head or shoulder throughout the series. The bird was subsequently nicknamed Hibird due to its connection to Hibari. It has been shown that Hibird understands Hibari's commands and what he says. An example of this is as Hibari is going to sleep atop Namimori Middle School, he says to Hibird, "Don't disturb me." Hibird flies away singing the school's anthem.
