Analysis: All belong to the kingdom Animalia-Chordates-Vertebrate subphylum-Ornithischia.

Ostriches belong to the kingdom Animalia: Phylum Chordates-Subphylum Vertebrates-Ornithischia-Platycophya-Ostrichidae.

Chickens belong to the kingdom Animalia - Chordates - Vertebrate subphylum - Ornithischia - Thrust - Chiniformes.

The classification of animals is according to the large to small kingdoms-phylum-class-order-family-genus-species! Let's classify!

Birds are divided into flat-chested, penguin, and protruding!

Protruding thorax is divided into two orders: Gooseformes, Falconformes, Chickens, Cranes, Gulls, Ospreyformes, Ospreyformes, Nighthawks, Buddhist Sangha, Schizomorphes, Passerinees, etc.

Like ostriches, there is also the Australian kiwi!

Ostriches are avian animals. Ostrich generally refers to the African ostrich, which belongs to the ostrich family Ostrich family and is one of the largest birds in the world. The ostrich is about 183-300 cm long, 240-280 cm tall, weighs 130-150 kg, has a triangular beak, a stubby trunk, and a flattened sternum.

Ostriches are on the verge of extinction in most areas due to human hunting. In 2016, the ostrich was included in the IUCN Red List of Threatened Species.

Ostrich evolutionThe ancestor of the ostrich was also a flying bird, and how it became what it is today is very closely related to the environment in which it lives. The ostrich is a primitive remnant of a bird, which represents an evolutionary direction in which animals gradually develop in the direction of tallness and running in open grassland and desert environments. At the same time, the ability to fly gradually weakens until it is lost.

The African ostrich's ability to run is amazing. Its toes tend to be reduced due to its suitability for running, and it is the only bird in the world with only two toes, and its outer toes are smaller and its inner toes are particularly developed. It jumps meters into the air and sprints at speeds of more than 70 kilometers per hour.

At the same time, the thick legs are also the main defense of the African ostrich**, and can even kill lions and leopards.

Habits of chickens

The hatching chicks, the body temperature is lower than that of the adult chickens3, it takes 10 days to reach normal body temperature, and the chicks are short and thin, can not keep out the cold, so the adaptability to the environment is not strong, must rely on artificial insulation, the chicks can grow and develop normally.

1 Chicks for 30 days old should be kept warm and kept in a clean and hygienic environment. Chicks that are more than 30 days old have feathers that are basically overgrown and accompanied by a long coat, so they do not need to keep warm. High body temperature and rapid development.
