Recently, the so-called "giant panda in bird" Brucea Javanica was found in Niukouyu City, Beijing. What's the matter with the discovery of Brucea Javanica in Beijing? What does it look like? Let's learn about it with Xiaobian.
What's the matter with the discovery of Brucea Javanica in Beijing
Recently, the so-called "giant panda among birds" Brucea Javanica appeared near Niukouyu in Fangshan District, which is the first time that this kind of bird has been found in this area. The population of Brucea Javanica is very rare, which belongs to the endangered bird species in the world. Before that, a new orchid variety named "Beijing beakless orchid" was found in Beijing.
The city's landscape Bureau said that these rare species were gradually found in Beijing, reflecting the continuous improvement of the city's ecological environment in recent years. According to statistics, in recent years, the number of wild animal species in the city has increased, reaching about 600 at present.
In order to better monitor the living conditions of wild animals, Beijing has set up 89 monitoring stations for epidemic focus and disease of wild animals. Not long ago, a rare bird named "Zhendan Brucea Javanica" was found in the monitoring station of the epidemic focus of terrestrial wildlife in Niukouyu City, Fangshan District.
The idiom '& lsquo; silent & rsquo; is believed to be familiar to all of us. It's very quiet, even the voice of crows and sparrows can't be heard. However, the newly discovered "Brucea Javanica" is not a crow or sparrow, but another kind of bird. Guan Xiangyu, consultant of the China Youth birdwatching Federation, said that the name "Zhendan Brucea" sounds strange. In fact, the word "Zhendan" comes from ancient India, which means the land of China, indicating that it is a unique species in China. At the same time, the number of Brucea Javanica is very rare, known as "giant panda among birds", which is a globally endangered bird species and has been listed in the international bird red book.
What kind of bird is Brucea Javanica
Guan Xiangyu used seven words to summarize the appearance characteristics of the Brucea Javanica -- round head, thick mouth and no neck. Among the Brucea javanica, the Sinian Brucea Javanica is of medium size, with a body length of about 19cm. Its living space is limited to reed marshes and mainly feeds on insects in reed clusters. Once insects are found, they will crack open reed stalks with their hard beaks and pick out the insects hidden in them to eat. Therefore, they are also called 'woodpeckers in Reed'. In recent years, plankton, plants, insects and a variety of fish and shrimps in the water of Niukouyu area of Fangshan have been massively propagated, attracting birds to come to live and overwinter.
Birds generally choose places with less human interference, good surrounding ecological environment, complete food chain and sufficient food. The diversity of bird species reflects the continuous improvement of ecological environment in this area to a certain extent. "Zhang Zhiming, director of the wildlife protection department of Beijing Municipal Bureau of landscape architecture and afforestation, said. The monitoring data of 89 monitoring stations of wildlife epidemic focus in Beijing also provide evidence. In recent years, the number of wild animal species in the city has increased, reaching about 600 at present.
In addition to birds, other rare wild animals are also frequently found. At the end of 2016, at the junction of Fangshan and Yesanpo, an environmental protection organization named 'Panther wildlife protection station' once photographed the national second-class protected animal - Wild impala. Local villagers said that they had not seen wild impala for more than ten years. In addition, large and medium-sized animals such as wild boar, impala and macaque, as well as small animals such as Chinese forest frog, tiger spot neck groove snake, grey forest owl and kestrel, have been found in Fangshan Mountain area.
In November last year, a new species of orchid without a litmus beak was accidentally discovered in Yanqing mountain area and named it 'Beijing beakless orchid', which is the only orchid named after Beijing in China. Up to now, only 17 Beijing beakless orchids have been found. The discovery also increased the number of wild orchids in Beijing to 24 species in 18 genera, industry insiders said.
According to the relevant person in charge of the Municipal Bureau of landscape architecture and afforestation, in addition to the 'Beijing beakless orchid', the 'Fanyu shady fern' has been found for the first time in Beijing, which is a relatively primitive fern with a very small number and both rarity and scientific research value. In addition, according to the field survey, the population and habitat of Ranunculus japonicus, a first-class protected plant in Beijing, are expanding. At the same time, rare plants, such as Shanxi Cypripedium, which have not been living in the past 40 years, and rare and excellent timber species, such as iron wood, which have not been recorded in Beijing, have also been found.
