Dino-Birds (tentative name) are a species of flying creature that inhabits numerous former Forerunner worlds. They appear in Halo 2 and Halo 3.

The Dino-Birds were first seen on Installation 05 on the level Delta Halo. They appeared again in Halo 3 on the multiplayer maps Guardian and Epitaph.

Despite being of presumably alien nature, these creatures bear a surprising similatity to ancient terran "pterosaur" species. A double set of wings and a long, rigid tail give them a striking resemblance to Earth's dragonflies as well. It is unknown how they came to populate so many worlds, but the fact that their habitats are in areas once inhabited, or at least visited, by the Forerunners suggests that they were transplanted either purposely or accidentally (like terran rats) by the Forerunners, or, given their pterosaurine nature, an even older civilization.

Trivia

 * In Halo 2 and Halo 3, players can shoot these creatures on several campaign and multiplayer levels. If you shoot them they will explode and fall to bloody pieces in mid-air.
