The Jubjub bird is a dangerous creature mentioned in Lewis Carroll's nonsense poems "Jabberwocky" (1871) and "The Hunting of the Snark" (1876).
Its voice when heard is described as "a scream, shrill and high" like a pencil squeaking on a slate, and significantly scares those who hear it, including the Beaver, who "turn[s] pale to the tip of its tail."
During the final battle, after the Mad Hatter's interference the Jubjub bird joins to fight for the Red Queen, only to later have its head crushed by a giant boulder from a catapult.
The Bluetones recorded a song titled "The Jub-Jub Bird", which was released in 1998 on their second album Return to the Last Chance Saloon.
[1] The song "Alpenglow" by Nightwish on the 2015 album Endless Forms Most Beautiful includes the line "together we slay another fright, every Jubjub bird, spooks of the past".
