Why ostriches look like they bury their heads

The low motion of tending an ostrich nest

An ostrich’s nest is a shallow scrape in the ground, not a deep hole. To tend the eggs, the bird lowers its long neck and uses its beak to roll them within the scrape. From far away, its head can line up with the earth while the rest of its body remains upright, making the movement look like the bird has pushed its head underground.

Why eggs are turned

Turning eggs during incubation helps keep the developing embryo from sticking to the inner shell membranes and supports even development. The ostrich’s beak is close to the ground as it moves each large egg, so the practical work of tending the clutch creates the familiar misleading silhouette.

The distinction is simple: the head is lowered to reach the eggs, while the eggs sit in a shallow nest. What looks like burial is a brief view of a bird caring for its nest.
