relationship between ostriches and zebras diet

The common ostrich (Struthio camelus), or simply ostrich, is a species of large flightless bird The common ostrich's diet consists mainly of plant matter, though it also eats invertebrates. .. nomadic groups of five to birds (led by a top hen ) that often travel together with other grazing animals, such as zebras or antelopes. Africa field is home to several species including Ostrich, Eland, have great eyesight and will often alert other animals of predators in the area. Belfast Zoo's ostriches live in a mixed African exhibit, with our Rothschild's giraffes and Grant's zebras. Habitat Savannah and grasslands. Diet - Omnivore.

She will drop to the ground and he will mount for copulation.

Common ostrich

The dominant female lays her eggs first, and when it is time to cover them for incubation she discards extra eggs from the weaker females, leaving about 20 in most cases. This uses the colouration of the two sexes to escape detection of the nest, as the drab female blends in with the sand, while the black male is nearly undetectable in the night.

This is believed to be the case due to the high rate of predation. Common ostriches in captivity have lived to 62 years and 7 months. Animals that prey on ostriches of all ages may include cheetahslionsleopardsAfrican hunting dogsand spotted hyenas.

A notable exception is the cheetah, which is the most prolific predator of adult common ostriches due to its own great running speeds. While the caudal end of the mesobronchus branches into several dorsobronchi. Together, the ventrobronchi and dorsobronchi are connected by intra-pulmonary airways, the parabronchiwhich form an arcade structure within the lung called the paleopulmo. It is the only structure found in primitive birds such as ratites.

Due to this the lack of connective tissue surrounding the parabronchi and adjacent parabronchial lumen, they exchange blood capillaries or avascular epithelial plates.

The use of air sacs forms the basis for the three main avian respiratory characteristics: Air is able to flow continuously in one direction through the lung, making it more efficient than the mammalian lung. It provides birds with a large residual volume, allowing them to breathe much more slowly and deeply than a mammal of the same body mass.

It provides a large source of air that is used not only for gaseous exchange, but also for the transfer of heat by evaporation. The air then flows through the anatomical dead space of a highly vascular trachea c. Inspired air moves into the respiratory system as a result of the expansion of thoraco abdominal cavity; controlled by inspiratory muscles. During expiration, oxygen poor air flows to the anterior air sacs [62] and is expelled by the action of the expiratory muscles.

The common ostrich air sacs play a key role in respiration since they are capacious, and increase surface area as described by the Fick Principle. Birds lack sweat glands, so when placed under stress due to heat, they heavily rely upon increased evaporation from the respiratory system for heat transfer. This rise in respiration rate however is not necessarily associated with a greater rate of oxygen consumption.

They can run about 40 miles an hour covering feet with a single stride. The ostrich will often use their wings as rudders to help change direction quickly while running. Ostriches will live in groups of about 12 birds. All the females of the group will place their eggs in the nest of the dominant female. A single ostrich egg is equivalent to 24 chicken eggs! Ostriches can often be found around other grazing animals like antelope and zebras.

Ostriches have great eyesight and will often alert other animals of predators in the area. It is myth that ostriches head their heads in the sand.

They will put their necks close to the ground to try and hide from predators, from a distance it appears that their head is in the sand. Eland are one of the largest hooved animals in the world. They are very adaptable animals with the ability to live in all environments except deserts, forests, and swamps.

They are some of the slowest antelope, running only 25 miles per hour.
