I have always believed that Ostriches when frightened bury their heads in the sand. Upon closer re-examination of this belief, I came to the following conclusions:

  1. Ostriches typically live in arid areas.
  2. Arid areas have dry surfaces.
  3. Dry surfaces need significant digging in order to create a depth in which an Ostrich can "bury" its head.

Is there any scientific research discussing this behavior and noting whether it indeed does or does not happen?

    I'm not really a skeptic per se, but I just looooove the question titles on this site :-) Commented May 17, 2011 at 15:57

1 Answer 1



From National Geographic:

Ostriches don't bury their heads in the sand—they wouldn't be able to breathe!

But they do dig holes in the dirt to use as nests for their eggs. Several times a day, a bird puts her head in the hole and turns the eggs. So it really does look like the birds are burying their heads in the sand!

From the San Diego Zoo:

.. 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.

From ABC Science:

The ostrich does many things, but hiding its head in the sand is not one of them.
Ostriches have three main strategies when attacked:

  • they can run away,
  • they can kick,
  • or they can try to hide (eg, when nursing the eggs).

When hiding, they will sometimes lay flat on the ground, with the long neck and head also on the ground. In the rippling heat haze of their native Africa, they can look just like a grassy mound.

From Straight Dope:

There are two theories about how this rumor got started.

According to the World Wide Fund for Nature, the ostrich lowers its head toward the ground in reaction to danger, especially when it's sitting on a nest (the female keeps the eggs warm during the day and the male sits on the eggs at night).

Male ostriches use their bills to dig shallow nests in the sand and move their eggs around. From a distance, this could look like the ostrich's head is disappearing in the sand. That's the other theory.

    This is a very well researched answer, and exactly what I was looking for. Thanks. Commented May 17, 2011 at 16:16

    To back this up, try to find a video of an ostrich burying its head in the sand on YouTube ;) Commented May 17, 2011 at 17:57

    interesting idea...check this out. It has a refutation of the behavior at (3:20) and theory as to why the myth began: youtube.com/watch?v=IfvmlDFxJZE Commented May 17, 2011 at 18:17
  • A lot of the images you see on Google Images also look as if they've been "digitally enhanced" or have things like shrubbery or a small mound in the way of the head to make it appear like that. Commented May 17, 2011 at 18:18
