Ostriches appear to sleep out in the open with other members of their herd.

How do ostriches sleep?

Ostriches exhibit a heterogeneous REM sleep state characterized by eye closure, rapid eye movements, reduced muscle tone, and a forward falling head, occurring with forebrain activity that flips between REM sleep-like activation and SWS-like slow waves.

Do ostriches need shelter?

Ostriches require between one and three acres of land in order to run and remain healthy. Build a simple shelter to protect the birds from harsh weather, and construct a fence to prevent the ostriches from escaping.
