Holotori

Holobirds, called Holotori (ホロ鳥) in Japanese, is an inter-branch subunit within Hololive, consisting of all talents who are canonically birds (with the sole exception of Oozora Subaru). The name "Holobirds" (ホロ鳥, Holotori) is a portmanteau of "Hololive" (ホロライブ), and "bird" (鳥, tori).

History
Holobirds originally formed as a trio consisting of Oozora Subaru, Takanashi Kiara, and Pavolia Reine, who are canonically a tomboy, a phoenix, and a peafowl respectively. This original trio is also nicknamed Turducken.

Oozora Subaru
Subaru was not a bird according to her official canon. However, Subaru is jokingly called a "duck" by fans owing to her voice's timbre and has fully embraced this aspect into her persona, and is thus fully considered a bird.

Takanashi Kiara
Although Kiara is canonically a phoenix, Kiara is also jokingly referred to as a "chicken", a reference to her being the owner of KFP, a chicken fast-food restaurant chain.

Pavolia Reine
A peafowl princess, Reine was nicknamed a "turkey" by fans as early as her debut stream. Peafowls and turkeys are distantly related and both are members of the family Phasianidae.

Nananshi Mumei
As a barn owl, Mumei was immediately considered a member of Holobirds upon debut by the other members.

Turducken
Turducken is an unoffical, self-declared subunit in Hololive. The Subunit was formed by Takanashi Kiara, Oozora Subaru, and Pavolia Reine. This group is a variant of the main HoloTori unofficial subgroup.

Naming
The Tur refers to Reine, who is based on a Peafowl, but has mistakenly called herself Turkey in occasions, the Duck refers to Subaru who has also been portrayed as a duck wearing her hat , lastly the Ken refers to Kiara who despite being a phoenix, has been called "chicken" and her mascot "Kotori" is a small chick. While not official under Hololive Production, their first appearance as Turducken was during a Worms stream on October 17, 2021.

Trivia
