The Mummy-nest Flyer is a small flying creature native to planet Darwin IV's northern tundra. It has a pair of fast-moving wings, which allow it to hover like a hummingbird; and a long rigid tail which is bent downwards. The Mummy-nest Flyer is so named because it makes its nest inside the mummified corpse of a much larger creature, dried out by the constant arctic wind. The nest's entrance is located where the corpse's head should be. Near it is a small bioluminescent appendage which likely helps the flyer to find its way to the mummy-nest.
