Ostriches nest communally, one cock bird to several hens. Once a clutch is laid, the dominant female incubates the eggs during the day. This lead hen will expel the eggs of weaker females that do not fit within the nest scrape. Her eggs are also at the center, making them less vulnerable to predation. The male sits at night, his black color making him undetectable in the darkness. I’ll share a look at the male brooding this nest in a future post.
