Dachora
From Metroid Wiki
The Dachora are mysterious creatures somewhat resembling ostriches found in Super Metroid and Metroid Fusion. Samus meets one Dachora in Super Metroid and presumably the same one in Metroid Fusion.
In Super Metroid, they teach Samus how to perform the Shinespark technique. The fact that Dachora can run at incredible speeds further gives them resemblance to ostriches.
In Metroid Fusion, the Dachora, along with Etecoons, take refuge in Samus's Gunship.
