Reporter squatting 丨 The new "delivery room" of Oriental Baiji, why is it the Yellow Triangle

□ Our reporter Li Ming

In the midsummer season, a hundred birds in the National Nature Reserve of the Yellow River Delta in Shandong, a beautiful body, a beautiful body, a black -wing and red feet.

The reporter watched a bird's nest with a telescope. Three young birds were resting beside the bird, and from time to time, they turned their heads to sort out feathers. The staff next to said that there were only two birds last year. In February this year, they successfully breed three young birds in the wild. Now they are already a family of 5.

The traditional breeding place of Dongfang Baiyu is not in the Yellow River Delta. The reporter came to the Huang Triangle Nature Reserve and visited the story of Oriental Baiyu's house.

From showing to reproduction

Zhu Shuyu, a senior engineer who has worked in the protected area for nearly 30 years, has witnessed the breeding history of Oriental Baiya on this wetland.

He told reporters that the Oriental White Birds will become tall and long under the careful care of their parents. When the length of the young bird's wings is close to a bird, after a period of practice, you can follow his parents to go out and learn predation skills.

In summer, the vegetation in the protected area is lush and rich in food. The reporter followed the staff of the staff and saw that three young birds went to the nearby wetland to find food from time to time. The long legs were involved in the water. The long beak was accurately attacked and the posture was elegant. Around them, there were some oriental white ravioli or foraging on the water, or dancing huge wings, showing a beautiful dancing posture.

"Oriental white crickets usually reproduce in high latitudes north of 40 degrees north latitude, while overwintering is between the Yangtze River Basin to the Pearl River Basin. It provides a good foraging environment. "Zhu Shuyu said.

Dongfang Baiyu appeared in the yellow triangle wetland for the first time more than 20 years ago. In 1997, the International Wetland China Project Office cooperated with the Oceania Office to conduct a survey of Chinese coastal birds. On April 27, Zhu Shuyu and colleagues and two foreign experts were conducting investigations near the 1,000 -two management station. In the swamp wetland on the north side of the reservoir, a group of large white poultry attracted Zhu Shuyu's attention. Essence "It's Oriental Bai Yan!" Zhu Shuyu shouted excitedly, and then the investigation team quickly recorded this precious image. A total of 19 was the first field confirmation of Oriental Baiyu in the Huangtantiang area.

"When we go back, we analyze the reasons. It is generally considered that the wetland protection management is very good, and it provides them with a good search environment." Zhu Shuyu said that since then, the protected area organizes the investigation and monitoring of Oriental White Mo every year, and it is even more even more. Pay attention to the protection of wetlands.

Since then, the number of oriental white ravioli monitored in the Yellow River Delta has increased every year, and the scope and residence time have increased. In May 2003, a corporate owner who made reed planting and ecological tourism around the reserved area called Zhu Shuyu: "Lao Zhu, more than 700 meters southeast of the protected area, a large oil field abandoned electric pole The bird's nest, you come to see what it is. "Zhu Shuyu rushed to the scene immediately and found that it was the nest of the oriental white ravioli. A bird was incubating. "This is the first Oriental White Loin Nest that we discovered. Unfortunately, the final incubation was not successful. Until 2005, on the high -pressure pole on the west side of the 50,000 -mu wetland restoration area in the protected area, 5 nests were discovered at one time. Among them, 2 nests were successfully breed 5, and 5 nests were successfully breeded in 2006. Since then, the breeding process of the Oriental White Burmese in the Yellow Triangle area has been opened. "

Nest

It is the continuous increase in the Yellow River Delta with the continuous increase in the Yellow River Delta.

In early 2000, the wetland degraded due to the water replenishment of the wetlands and the pouring seawater. To this end, the Management Committee of the Nature Reserve applied for the second phase of renewal projects in the protected area, and planned a 50,000 -mu wetland restoration zone at the Dawen Liu Management Station.

"The wetland repair zone planned the deep and shallow water areas of the Dapo Bi, built a variety of micro -ground shapes, and built 3 dams, 4 water drainage canal, multiple connecting gates, and the water in the spring of 2003 was very good." Zhu Shuyu introduced it. At that time, there were nearly 200 oriental white -bellies, and rare birds such as red -crowned cranes, black -billed gulls, and big swans also increased significantly.

The continuous improvement of the environment has allowed more and more Oriental Baiyu to plan to settle here. However, there are no tall trees in the yellow triangle area. Oriental White 鹳 often choose to be a nest in high -voltage poles. This is a threat to power safety, and the lack of nest materials also makes some nests built by Oriental White Board less.

"I remember very clearly. On May 1, 2004, a strong wind was overturned to the ground with a pair of oriental white pupa on the top of the high -pressure thread. At that time, he began to think about how to build an artificial nest for them and attract more Bai Yan to come here.

Subsequently, Zhu Shuyu checked the literature, conducted a nest survey, and studied the breeding habits of Oriental White Burmese. In the end, the construction plan of the Oriental White Poor Point Point was designed: 15 meters of high poles, 3 meters buried, 12 meters above the ground, and nickel -plated steel on the top. The bird's nest skeleton has three models from 2.5 to 3 meters. In the winter of 2008, the 21 -person workers who invested 130,000 yuan set up.

"The effect of doing this is obvious. In the spring of 2009, nearly 70%of them were in. Until now we have made 115 people's nests, and the occupancy rate is nearly 80%." Zhu Shuyu said.

In addition, the protected area has also implemented the Eastern White Cycling Habitat Protection Project. Oriental white -crickets and black -mouth gull habitats create optimization projects have greatly improved the oriental white ravioli habitat environment. Build a monitoring network

Three tripods, cameras, telescope, positioning devices ... Wu Lixin, a 51 -year -old senior engineer at Dawenliu Management Station, the first thing after work every day is the backpack with nearly 10 kilograms of equipment on the back. Both must be "hit".

Tour more than 100 kilometers a day, and data such as inspection location, latitude and longitude, population status and quantity must be carefully recorded and uploaded to the scientific research center of the management committee. "The accumulation of these data is important to the protection of birds." Wu Lixin told reporters.

The process of patrol and monitoring is an important part of scientific research and protection. In 2006, the protected area issued the "Oriental White Cycling Protection Regulations", which made specific regulatory requirements in terms of protection scope, measures, systems, patrols, etc. At the same time, a detailed patrol monitoring system has been formulated, three management stations, and 5-6 routes for each station, which must be patrolled once a week. "By determining the sample line, sample point, sample recipe, observe records of bird status, vegetation distribution, water quality, soil, and food land resource status, so as to carry out more targeted protection." Essence

In order to better understand the information and biological characteristics of Oriental Baiya's habits, migration paths, health status, and providing more valuable information for protection, starting in 2010, the protected area cooperates with the Anhui University and the Chinese Academy of Forestry Sciences every year for Oriental White Board Installation Satellite Ring Zhi. "At present, 73 Oriental Baiyan wears satellite trackers, color rings, and metal rings. Through the Internet+global positioning system, in real time, the breeding and migration dynamics of wild birds." Zhao Yajie said, in addition, high -definition video surveillance was installed. More than 50 places.

Beginning last year, the construction of the "Sky and Sea" integrated monitoring network was also officially launched. The ecological monitoring platform with a total investment of 16.79 million yuan, comprehensively uses information technology methods such as the Internet, big data, the Internet of Things, remote sensing, radar, drone, and other information technology. Popular science platform.
