Chozo

The Chozo were an ancient, birdlike humanoids that are found in the Metroid video game series. They're a prominent part of the evolving story of the series and are credited for saving Samus Aran long ago. They're capable of space travel and traces of the species can be found on multiple planets including but not necessarily limited to Elysia, Tallon IV, Bryyo, SR388, and the now destroyed Zebes.

They're known as being a peaceful, albeit superior, species that traveled the worlds, trading their technology with other species such as the Luminoth and multiple others. They're knowledge of science and technology is unarguably beyond compare in the Metroid series, though how their species became extinct is unknown.
