"Ozzy Ostrich"
A few interesting Ostrich facts:
A zoo favorite of adults and children alike, the ostrich is truly an
interesting animal. From its large size to its odd feathers, this
flightless giant is unlike any other. An African native, the ostrich is
the sole surviving member of its biological family.
The ostrich is the world's largest living bird. The average adult male
is between 8 and 10 feet tall and weighs in at over 250 pounds. The vast
majority of the bird's body weight is encapsulated in its long and powerful
legs. A single ostrich stride will carry the bird 12 to 15 feet.
Ostriches are able to achieve speeds greater than 40 miles per hour when
running and they are able to maintain that speed for more than 30
minutes at a time. Unlike other birds, the ostrich has only two toes.
This adaptation reduces the drag coefficient of the limb, enabling the
bird to attain greater speeds than many of its predators. Also, each toe
ends in a sharp, formidable claw and each leg is capable of kicking
with enough force to crush a skull.
The ostrich is a member of an ancient bird family called the ratite. One
of the distinguishing characteristics of this group of birds is
although they have wings, they cannot fly. The wings of the ostrich are
used for balance instead. It extends its wings when running and then, if
the bird suddenly needs to change directions, the wings act as a
rudder, helping to smoothly steer the bird along a different route and
possibly evade predators. The wings are also used in mating rituals and
courtship displays. A domineering bird will raise its wings while a
subservient one will allow its wings to sag.
Ostrich feathers are not like ordinary bird feathers. The individual
fibers hang loose, rather than sticking together. The feathers of the male ostrich are generally
black with white showing on the tips of the wings. The male uses this
vivid color scheme to attract the attention of passing females. Holding
the wings as wide as possible, a male will approach a female, stamping
his large feet as he goes in hopes of impressing the light-brown lady.
If he manages to gain her approval, the two birds will mate.
The ostrich has a well-developed sense of sight and eyes that are almost as big as baseballs. The eye
orbs are large and so important to the bird's survival, that the
majority of the skull is used to house
and protect them. Accordingly, the brain is a good deal smaller than
either one of the eyeballs. This may explain why the ostrich is so
easily trapped by predators; it can run fast, but it can't think on its
feet.
