OSTRICH FEATHER CATEGORIES
There are 5 types of feathers: tail feathers, short body feathers, long body feathers, and floss and wing plumes.
The chick feathers are of the wing
plumes category and appear soon after hatching. These plumes are ripe at
6 months and the quills 2 months later. They are brown on the top and
dark grey on the bottom of the plume.The chick feathers on the lower
part of the body and under the belly are white.
After about 5-6 months, the chick
feathers begin to lose these characteristics, and are plucked because
they are not of high quality. After 2 years, the sex of the ostrich is
clear, because the male has black body feathers, while those of the hen
are a dull grey.
The female feathers are a dull grey
colour, ideal for breeding during the day because she is
well-camouflaged. With the grey feathers, she has creamy-white wing,
tail and ventral plumes. The white on the feathers forms a unique
pattern along the shaft, like a human fingerprint.
The male feathers are black in colour,
with the exception of the white wing-tips and tail-plumes and this is
perfect camouflage for breeding at night. This is the reason why the
males will guard and breed the eggs at night, and the females, with
their dull grey feathers, breed during the day. Tail plumes are normally
a brownish-orange colour because of the red Oudtshoorn dust, which can
be easily washed off to return to its original white colour. The lower
30cm of the neck is covered with feathers, and the remainder with short
downy feathers and hairs, as well as the head that is covered with
short, straight hairs.
HOW FEATHERS ARE HARVESTED
A prize male ostrich yields around
40-50 plumes. Between 200 and 300 wing plumes would make 1kg, whereas
female wing plumes are even lighter. The total “harvest” from one bird
at one plucking weighs about 2kg including body feathers. IF the
feathers stay in the ostrich after they become “ripe”, they lose their
lustre and become dull (hence the bird must be plucked, while the quills
are still “green”). The quills are pulled out to prevent irritation to
the bird and damage to the new feathers starting to grow behind the
quills. The ostriches are never left completely bare at any stage, to
prevent sun burn and skin damage.
FEATHER PRODUCTS
Feather boas are wing plumes
“plucked” from the shaft of the feather and tied together with a needle
and string. Approximately 40 wing plumes are used to make a 1.5m boa,
and takes about a day and a half to make.
30 grams of body feathers are used to make one feather duster.
Feather dusters can be successfully washed and dried because the
ostrich has no oil glands and the feathers are therefore not oily. The
reason why ostrich feathers work so well as feather dusters is because
once they are stroked, they become charged with static electricity. This
helps the dust particles to stick to the feather, unlike other feather
dusters that just move the dust around.
