Shedded Mummy Nest

This 3.5-meter-tall mummy has something strange in its "head." There is a dark opening just beneath the dimly glowing bio-light. The emptiness in the hole seems to confirm that this is nothing more than a mummified carcass. But why is the bio-light still glowing? The answer is very strange. A mummy-nest flyer will often appear and circle the mummy-nest. Within a minute or so, the black flyer swoops down; with blurred wings it hovers, then lands upon the mummy's "head" and disappears into the hole. The flyer then never seems to reappear. So convincing is the carcass's moribund appearance. In spite of the bio-light, the frozen husk appears as wind-desiccated as any dead creature on the tundra. It turns out that this cryptobiotic mummy-nest is providing warmth and shelter to the little flyer.
