To show dominance, an ostrich holds its head up high and lifts its wings and tail feathers; to show submission, the head, wings, and tail droop down. Unlike most birdsâ feathers, ostrich feathers are loose, soft, and smooth. They donât hook together the way feathers of other birds do, giving ostriches a shaggy look.The feathers can also get soaked in the rain, because ostriches do not have the special gland many birds have to waterproof their feathers while preening.ctually, thatâs a myth: ostriches do not bury their heads in the sand! When an ostrich senses danger and cannot run away, it flops to the ground and remains still, with its head and neck flat on the ground in front of it. Because the head and neck are lightly colored, they blend in with the color of the soil.
