About DuDu Bird:
DuDu bird has always been regarded as a big stupid bird. It weighs about 20 to 30 kilograms. It has a big hooked beak, bright feathers and a small tail to decorate it. In fact, DuDu birds are easily distinguished from other birds for the simple reason that they can't fly.
1598, Portuguese sailors landed in mauritius island, Indian Ocean, and suddenly discovered a unique and unknown bird-DuDu Bird.
Some people say that the DuDu bird evolved from an African Trelon pigeon that ate fruit. They stayed in mauritius island. Because there were no other kinds of biological interference at that time, there was a lot of food around, so they didn't fly around in the sky for food, and their wings naturally degenerated. Just because they can't fly, their nests are naturally built on the ground. It is said that the larger the territory of birds, the stronger their defense ability will be. A person who has been to mauritius island described that DuDu birds protect their nests by stacking palm leaves about 18 inches, and parents take turns to hatch eggs. In fact, their chicks also have the ability to resist intruders, but they are no match for intruders and the dogs and pigs they bring. So both their eggs and themselves were sacrificed to the five zang-organs temple or destroyed. There is another factor that makes DuDu birds extinct, that is, deforestation, which greatly reduces the food of DuDu birds. top
Looking for a bird:
After the extinction of DuDu bird, several scientists tried their best to find information about DuDu bird, some through bird eggs, some through remnants, and some through paintings left at that time.
Among the people who painted it, they were surprised to find that in the sketches, watercolors and oil paintings about the bird in 1598- 1655, the bird in the picture after 1626 is the bird in the general impression, and some pictures show that the shape of the bird will change seasonally with the passage of time. Duckbirds feed on some seasonal foods, fruits and things on the ground, but strangely, almost all the Duckbirds painted by European painters are chubby. In this regard, they think that the DuDu birds brought back are "fattening" because they are fed indefinitely.
Others explained why the DuDu bird is fat. They say that the body shape of the DuDu bird does change with the seasons, but it also makes the DuDu bird need to store more fat for a rainy day. Before enough food arrives (about five months), they will be hungry, and with their low metabolic rate in the body, on a subtropical Indian Ocean island,
John reed is the last protected bird in Britain. After his death, his friends collected it for him. But he didn't keep it properly and donated it to Oxford University. Oxford University didn't keep it properly (except the bones of the head and feet), and everything else was burned as garbage. So it can be said that it is easy to find bandits!
In fact, it is a bit sad that for more than 350 years, the general impression of the largest and most famous pigeon in the world comes from the existing paintings, and the DuDu bird is wrongly described as a plump and slow-moving bird. In fact, like other birds living in Mauritius, they also have seasonal fat changes to cope with climate change, but it should not be as exaggerated as in oil paintings. top
What if there are no birds?
The tragedy of the DuDu bird once again illustrates the irreparable impact of human beings on the environment, and it is also a living and bloody example. However, the DuDu bird didn't walk alone, but also took away a tree called Calvaria. The seeds of this tree need to be digested by the DuDu bird to germinate. Shortly after the DuDu bird left, the Calvaria tree disappeared.
Therefore, we gradually face up to the importance of ecological protection and set up a common saying about the ecological environment: I hope it is not too late for us to act!
