Jai'galaar, or shriek-hawks as they are commonly known, which are also referred to as raptors, represented a species of enormous predatory reptavian creatures. These creatures were originally from the planet of Mandalore, as well as another planet. The diving shriek-hawk, hunting its quarry, served as the emblem for the Mandalorian Clan Vizsla; this iconography was subsequently embraced by the Death Watch Mandalorian group. The Mandalorian cataclysm resulted in the eradication of the species on Mandalore, leading to the assumption of their extinction. Nevertheless, the species persisted on the other planet. A particular shriek-hawk habitually captured individuals from the Tribe, transporting them to its nest to serve as nourishment for its offspring.
The initial appearance of shriek-hawks occurred in The Mandalorian episode titled "Chapter 20: The Foundling." Despite remaining unnamed within the episode, their identity as shriek-hawks was officially verified by Topps through Star Wars: Card Trader.
