Original title: "the most mysterious bird in the world" Hainan oyster is now in Changting, Fujian Province
'This is the first time in Fujian Province to record the breeding process of Hainan oyster completely. ' Lin Qingxian, a well-known bird expert and doctor of School of environment and ecology of Xiamen University, led a team to Shifu village, Datong Town, Changting County, Fujian Province for the third time on the 26th to continue to observe the rare breeding process of Hainan oyster. Zhu Yusen, a retired photographer from Minxi daily, discovered Hainan oyster in Changting and observed its breeding process. Since his retirement in 2016, Zhu Yusen has carried out bird survey and shooting in Changting at his own expense. Over the past three years, he has photographed and recorded more than 280 kinds of birds in 64 families of 18 orders.
On the morning of April 20, 2019, Zhu Yusen and Local Forestry Bureau cadres Qiu Jiarui and Liu Hui conducted a bird survey in Shifu village, Datong town. In a pine forest near a water area, two adult Hainan oyster birds and their nests were found. There were two newly hatched young birds and an egg in the nests. Afterwards, they set up an observation point in a hidden place about 100 meters away from the bird's nest. Now they have been observing for 37 days. Every day from early morning to dusk, they insist on shooting and recording. The video and image data are more than 400g. Finally, they have found out the developmental process of Hainan oyster, such as the emergence of its shell, the growth of its fledgling, the flight of its feathers, the fading of its fledgling, begging for food, practicing its balance and flying ability, as well as the parent birds' going out to hunt, the growth of its young The laws of homing have improved the breeding data of Hainan mangrove, which is extremely rare in the world. Hainan oyster, also known as Hainan tiger spot oyster and Hainan night oyster, is named after the first type specimen collected by the British from Wuzhishan, Hainan Island in 1899. At present, Mystus hainanensis is in an endangered state. It is listed in the World Red Book of endangered birds by the International Committee for the protection of birds. It is one of the 30 most endangered birds in the world; Birds is listed as an endangered species, is the second class national protected animals.
According to the literature, since Hainan oyster was first discovered in 1899, it was not until the 1920s and 1930s that it was found in Zhejiang, Guangxi, Fujian, Hainan and other places. However, there are few image records, and the breeding data are even rare. For a long time, Hainan has only kept one specimen in the British Museum. It is difficult to be observed because it has the habit of ambushing in the day and coming out at night and acting mysteriously. Therefore, it is called 'the most mysterious bird in the world'. Because of its small number and narrow geographical distribution, it is also known as' Panda in birds'. In the 1960s and 1970s, zoologists once thought that Hainan oyster had been extinct. It was not until 1990 that it was rediscovered.
"Hainan oysters have high requirements for their living environment. The Hainan oysters found in Changting this time belong to resident birds rather than migratory birds, which proves that Changting's ecological environment is getting better and better and has become an ideal habitat for more and more birds." Lin Qingxian told reporters. The picture shows a pair of Hainan minnow adult birds.
In recent years, remarkable achievements have been made in soil erosion control and ecological environment protection in Changting County. Compared with 2000, the area of soil erosion in Changting decreased from 1056600 Mu to 369000 mu; The rate of soil erosion decreased from 22.74% to 7.9%; The forest coverage rate increased from 59.8% to 79.8%. " Cao Weiqing, director of Changting County Forestry Bureau, is very proud of this. The picture shows a family in Hainan.
