Why do ostriches bury their head in the ground?

Actually, that’s 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. From a distance, it just looks like the ostrich has buried its head in the sand, because only the body is visible.

who cares, you ever get chased by an ostrich. its not fun. When I was little me and my cousin were on this trail when 2 escaped ostriches came out of nowhere and chased us down the trail... You can't even make that kind of sh*t up
