Awesome Animals: The Ostrich

Source

Ostrich (Struthio camelus)

  • Ostriches are the largest living bird in the world.
  • Ostriches are flightless, but can run at speeds of up to 40 miles per hour.
  • Ostriches can live for up to 75 years, but the average life span is 50 years.
  • Ostriches are monogastric, meaning they only have one stomach compartment.
  • Ostriches mainly feed on seeds, roots and plant material, but are omnivores and will occasionally go for the small insect or lizard.
  • Like diving ducks, ostriches will swallow pebbles to assist the grinding of food in the gizzard.
  • Ostriches are nomadic, meaning they like to move from place to place.
  • Living in grassland and semi-desert areas, the ostrich can go for long periods of time without water and gets most of its required moisture from its food.
  • The ostrich spends 70 to 80 percent of its daylight hours feeding and digesting. Movement and the continuous ingestion of food are both essential components of their dietary physiology.
  • The color green stimulates the ostrich to peck.
  • Ostriches begin to breed between two and four years of age.
  • The average ostrich gestation length is 35-45 days.
  • The ostrich mating season begins in late March or early April and ends by September.
  • Ostriches live in grasslands and semi-desert areas.
  • In more urbanized areas and in captivity, ostriches sometimes suffer from Hardware Disease. Hardware Disease is caused by the ingestion of metal objects that interfere with digestion and can cause gastrointestinal trauma.
  • Ostriches have very strong, powerful legs with sharp claws. Ostriches in captivity are prone to kicking and scratching.
  • During the mating season male ostriches are especially aggressive, often fighting over a harem of three to five hens.
  • Ostriches like to live and travel in groups
  • Ostriches like the water and enjoy bathing.
  • Male ostriches can grow between eight and nine feet tall and can weigh up to 400 pounds (females tend to be smaller).
  • Ostriches are oviparous, meaning several females will lay their eggs in the same nest.
  • Both male and female ostriches share parental duties when caring for their young. Usually males will sit on the nest during the day then let the female take over at night.

I also believe they have genetic ties to dinosaurs also. Thank you for sharing.

I remember the scary ostrich. When I was little, on my grandfather's farm, they always used to chase me, and I would be scared to death!

I noticed in Indiana that the Aumish in Odon, imported Ostrich! It was quite spectacular to see an Ostrich in the country as you drove past them on the roads! I often wondered how the Aumish keep from getting injured when their giving them water or food!

It seems like ostrich husbandry would be a fine science- they get quite angry and I can only imagine all the dodging one must do while caring for them! lol
