Ostriches
usually weigh 63-145 kg (140-320 kg), East African Ostrich Race (S. c.
Massaicus) with an average of 115 kg (250 lb) for males and 100 kg (220
lb) in women, and the name subspecies is pounds (240) on an average of
111 kg in adults unsexed. Exceptional male ostriches (nominal
subspecies) weigh up to 156.8 kg (346 lb). When they reach sexual
maturity (2-4 years), male Ostriches can be from 2.1 to 2.8 m (6 feet 11
inches to 9 ft 2 in) to be in height, while female Ostriches range from
1.7 to 2 m (5 ft 7.6 ft 7 in) tall.
New girls are yellow-brown, with
dark brown spots. Age, ostriches weigh around 45 kg (99 lbs). The
feathers of adult males are mostly black, with white primaries and a
white tail. Women and young men are gray-brown and white. The head and
neck of both male and female ostriches is almost naked, with a
thin layer below. The skin of the neck and thighs is pinkish gray
females, while the male is blue-gray, gray or pink, depending on
subspecies.
The legs of the Ostrich are unfeathered and show bare skin,
with the tarsus (the lowest part of the straight leg) is covered with
scales: red to black women. The hock ostrich is the largest of all
birds, measuring 39-53 cm (15-21 inches) in length. The bird has only
two fingers for each foot (most birds have four).
Ostriches can be run at a speed of over 70 km / h (43 mph) and
able to cover 3-5 m (9.8 to 16 feet) in a single step. The wings are
used in mating displays and chicks shadow.
The feathers lack the tiny
hooks that bind together the smooth external feathers of flying birds,
and so are soft and fluffy and serve as insulation. It can tolerate a
wide range of temperatures ostriches. Ostrich sternum is flat, lacking
the keel to the wing to bring the muscles, birds in flight. Like all
ratites, the Ostrich has no crop, and it also lacks a gallbladder.
Unlike all the birds, the Ostrich secretes urine separately from
faeces. All the other birds Store urine and feces were combined in
coprodeum, but the shops chair ostrich in the rectum terminal.
Unlike most birds, with males. The first fossil ostrich-like birds is the Palaeotis live close to the Asian steppes, from the Middle Eocene, a ratite size initially believed to be a bustard. While the relationship between the African species is relatively simple, a large number of Asian species of ostrich from fragmentary remains, and their relations are described and their relationship with the African ostriches is confusing.
