Tip 1: Which bird lays the largest eggs
The largest of the birds is the African ostrich. The name of this flightless bird is translated from Greek as a "sparrow-camel". This giant lays the largest eggs.
Very often the size of eggs laid by birds,is not proportional to the size of the bird itself. Usually large-sized eggs with a large amount of nutritive yolk lay those species in which the chicks hatch relatively developed and capable of almost immediately taking care of themselves. Of the small eggs, the chicks are born helpless and weak.
Ostrich chicks
The ostrich chick shows strength in the egg. He pierces the thick shell within an hour, resting his legs on both ends of the egg and pecking his beak until a hole appears. Having made several such holes, the chick strikes the shell with the back of the head, getting at the same time the hematoma, but achieving the goal. The ostriches appear from the eye sighted and active, weighing up to 1.2 kg. The next day they are able to travel with their parents in search of food, and at a month's age to run at a decent speed - 50 km / h. It is interesting that the chickens of ostriches from different groups can mix at a meeting, and there is no way to divide them. Parents are fighting for chicks and the winners take care of the whole group.Lifestyle ostriches
An adult ostrich has an increase of up to 250 cm and a weight of about150 kg. He has a long naked neck and a small head with big eyes. On the back of the ostriches there are underdeveloped wings, on the legs - only two fingers, one of which at the end contains the resemblance of a horn hoof. Strikes of a powerful ostrich's leg are terrible even for lions, if these birds are protected in the protection of their territory. Usually, in case of danger, the ostriches fling, making huge three-four-meter steps at a speed of about 70 km / h. As a rule, ostriches are kept by small families. This is a kind of harem with one male, four or five females and chicks. Ostriches are fed with plant food, but sometimes they eat insects and small animals. At a young age, ostriches eat animal food. The ostriches do not have teeth, so they grind stones, pieces of wood and other objects to grind and digest food in the stomach. The life span of an ostrich is about the same as that of a man - 70 years.Eggs of ostrich
The male forms a pair with one female from the harem, withwhich then incubates the chicks. The remaining females lay eggs in a pit about 60 cm deep, which the male prepared. Eggs of straw-yellow, white or dark green color weighing 1.5-2 kg in length reach 15 - 21 cm. The masonry can contain from 15 to 60 eggs. Nasizhivanie lasts from 35 to 45 days. Many embryos die from hypothermia, as they often remain unattended. Spoiled eggs are broken by ostriches, and flies that fly on them serve as an animal food for hatched chicks. There are ostrich farms on which birds are raised for meat, feathers and eggs. Due to the thick shell eggs do not deteriorate for three months, and in the refrigerator can be stored and up to 6 months. The taste of ostrich eggs resembles that of chicken.Tip 2: Which bird is the most beautiful in the world
