Ratites-Ostrich, Rhea & Emu
Ratites are a group of birds named for their flat or "raft-like" sternum. Unlike most birds, their bones have no air cavities and their wings are vestigial in size, making flight impossible. Unable to fly, they have highly muscular legs and are well adapted to running.
Ostriches are the largest living birds, coming from the deserts and savannahs of Africa. Some males weigh as much as 155 kg and stand 244 cm. They are capable of running at speeds of 40 to 60 km/hr. Ostriches are primarily vegetarian, but can easily kill attacking predators with their powerful kicking ability. Females are a dusty, grey-brown in color, while males are black. They are polygamous, the senior hen sitting on the nest during the day, and the cock tending the nest during the night. Eggs are 15 cm long and 12 cm in diameter. The chicks are born precocial after incubating for 42 to 48 days. In frames 1:24 to 1:30, a male is doing its courtship dance.
Rheas live in flocks on the pampas and savannahs of South America, where they feed on vegetable matter or small creatures. Males get to the height of 170 cm. In spring, the cocks become very aggressive as they select and segregate their harems of 3 to 7 hens. The cock will incubate some 50 eggs by those in his harem. Incubation takes 40 days. In frames 2:40 to 2:47, a male rhea is attacking me.
Emus are the 2nd largest living bird, and reside throughout mainland Australia. They are relatively monogamous during breeding season and have an extended courtship coupled with more aggressive activities, but (as with rhea) the males solely incubate the eggs for a period of about 2 months.
Also a ratite, but not shown, are cassowary, which are similar to emu and are found in Northern Australia and New Guinea. They are normally solitary by nature and live in forests.

emu chicks hatching, a complete success!
3:33
This is a continuation of my other short video "Emu Egg Facts". Now, 51 days later, here is the hatching sequence. I will post a longer version of this hatch later, for those of you who want to hear everything and have the time to watch a 10 minute video. All five baby emu are recovering nicely in the brooder and will soon be transferred to the Emu cottage. タグ:emuincubationbrooderhatchingsecond 投稿日: April 20, 2008, 12:33 pm 閲覧数: 672 投票: 5.00(５点満点) 5 人の平均
emu egg facts, size and weight
1:55
These are Emu Eggs, the Emu is native to Australia and is the second largest bird in the world. The largest is the Ostrich. These are fertile Emu eggs, which are prepared for incubation. Incubation can take up to 52 days and requires lower incubation temperatures than chicken eggs. A chicken egg hatches in 21 days. IF the incubation process is successful, you'll see a new video post in April 2008, showing the hatchling Emu. An adult Emu may stand 6 feet tall and weigh up to 150 pounds. タグ:emueggssecondlargestegg 投稿日: March 5, 2008, 3:00 am 閲覧数: 1712 投票: 4.70(５点満点) 6 人の平均
