Mama Ostrich turning her eggs, Chiang Mai, Thailand
As flightless birds, ostriches are unable to build nests in trees, so they lay their eggs in holes dug in the ground. To make sure that the eggs are evenly heated, they occasionally stick their heads into the nest to rotate the eggs. Ostrich eggs are incubated by the females by day and by the males by night. This uses the coloration of the two sexes to escape detection of the nest, as the drab female blends in with the sand, while the dark-colored male is nearly undetectable in the night.
