Одне гніздо — кілька самиць і двоє батьків | One nest, several females, and two caregivers

Ostriches may share a communal nest among several females. A male mates with one or more females, and the dominant female and others may lay eggs in the same nest. Incubation and care are not handled by the male alone: typically the dominant female incubates by day, the male by night, and both help protect the chicks.
