A cockerel, Gullinkambi ("golden comb"), resident in Valhalla is, in Norse mythology, one of the three cockerels who crow to announce the beginning of Ragnarok.
"Crowed o'er the Æsir Gullinkambi,
which wakens heroes with the sire of hosts;
but another crows beneath the earth, a soot-red cock,
in the halls of Hel."
