To ask Zhengzhou what animal attracts the most attention this year, it is not the introduction of new species in the zoo, but the arrival of verrucose swans in Beilong lake and Jialu River in front of their homes.
At present, there are 7 adult verrucosa swans in Zhengzhou, including 5 in Beilong Lake Wetland and 2 in the upper reaches of Jialu river. With the newly hatched baby swans, the total number of Verrucosa swans in Zhengzhou has reached 20.
Before that, there was a phenomenon that swans died after giving birth in Sanmenxia. Can Zhengzhou born Swan babies survive smoothly?
[surprise] photography lovers' dream come true: to shoot swans at home
In the words of photography enthusiasts, "it's really a dream come true. I didn't expect that swans could be photographed at home." It is understood that in the past, if you want to get close contact with swans, you often have to drive for hours to Sanmenxia Wetland Park.
Since late February this year, a group of photographers carrying "long guns and short cannons" in Beilong Lake Wetland Park have been on time at the shore before dawn. Photography enthusiast ou junzhan is one of them. Over the past few months, as long as he was free, the European Army wanted to run to Beilong lake with photographic equipment on his back. There was a group of wild verruca swans, which had been affecting his heart.
"Other birds are different. Swans are not afraid of people, and they are particularly flattering," the European military said This is because this kind of swan is relatively large, and it will have a long sliding distance before taking off. Every morning, the warty nosed swan will slowly stretch its wings to practice flying, which is also the best time for photography lovers to capture the camera.
In the process of love, a pair of warty nosed swans often act in the same way. Sometimes, they step on their backs, compare their hearts, and bathe each other, which makes the photographers enjoy themselves.
In addition, verrucosa Swan itself is a rare species, and it is a national second-class protected animal. Its migration route is mainly in western provinces of China, such as Mongolia, Gansu, Qinghai and so on.
[episode] eggs were laid five days after being rescued because of kite string
Different from other photography enthusiasts, the European army war preferred to use a video to record the warty nosed swans in Beilong Lake Wetland Park. In his computer, the materials of the swans alone stored more than 500g, covering the whole process of love, mating, egg production and hatching of the two swans.
On March 22, European soldiers and other photographers who came to observe the swans as usual found that the warty nosed Swan couple, who used to be very punctual, suddenly disappeared today. Did they fly away? Or did something happen?
Later, the European military UAV aerial photography, and finally found two swans in the grass of autumn leaf island. "When you zoom in, there seems to be something wrapped around the left leg of the female swan. If you look closer, it's a kite line." The European army recalled.
After the swan was found in distress, nearby birdwatchers contacted the water police station in Zhengdong New District. Finally, with the help of Zhengzhou wildlife protection station, the injured verrucosa swan was successfully rescued.
Five days after the incident, on March 27, the European army found that the couple laid a turquoise egg in the nest. In the following days, the female Swan laid six more eggs. After two swans hatched in turn, on May 12, four swans broke their shells and on the 13th, two swans stuck their heads out of the eggshells.
[reason] environmental improvement is the key for Swan to choose to settle down
In the past ten years, the water environment of Jialong lake has been improved gradually from the introduction of the Yellow River basin to the comprehensive improvement of the water environment in the north of the Yellow River. People in Zhengzhou were surprised to find that the water in the river became clear and there were more birds.
"According to the migratory habits of migratory birds, after a short stay here, they should leave in February, but they did not leave and settled here. This shows that Beilong lake, with its rich water and grass and pleasant scenery, has made swans fall in love with it." Zhengzhou City Forestry Bureau wildlife protection director shangguangzhu said.
"Verrucosa swans have strict requirements on water quality and environment. They can choose here, which indicates that the water quality and ecological environment of Beilong lake and Jialu River are very good." Dong Chaowei mentioned that verrucosa swans have strict requirements on water quality and environment. For example, swans from the Jialu River swam along the river from the downstream to the upstream before nesting and breeding. As a kind of migratory bird, verrucosa swan can not rule out the possibility of migration along with the change of seasons in the future. "But the situation that migratory birds have left behind has appeared in Sanmenxia. If the verrucosa swan family falls in love with the beautiful city of Zhengzhou, it is not ruled out that they will settle down here for a long time in the future." Dong said.
[question] can Swan babies living in high latitude survive the summer in Zhengzhou?
On May 26, two verrucosa swans in the upper reaches of the Jialu river successfully hatched 7 Cygnus. So far, the total number of "Zhengzhou native" verrucosa swans has come to 13.
"These 13 baby swans need at least one and a half months to be able to take care of themselves and five months to be able to fly." Dong Chaowei, director of Zhengzhou wildlife rescue station, said that the group of Cygnus are always following their parents. When they are tired, they will step on the swan's back and enter their parents' arms like a coquettish.
It is understood that the reproduction of wild verrucosa swans in beilonghu Wetland Park is the second case of successful habitat and reproduction of wild swans in Henan Province after Sanmenxia Wetland Park. Unfortunately, some wild swan babies in Sanmenxia did not survive due to various reasons.
In order to provide a comfortable growth environment for "Swan babies" from Zhengzhou, on May 29, Zhengzhou Forestry Bureau, Zhengzhou Forest Public Security Bureau, Zhengzhou wildlife rescue station and other relevant departments put forward protection suggestions on strengthening the protection of swans and creating excellent habitats in Beilong Lake wetland, and set up special warning lines and warning signs in the living areas of Verrucosa swans.
With the coming summer heat, can verrucosa swans and baby swans, who usually live in high latitudes, adapt to the temperature and humidity in Zhengzhou? Dong Zhaowei told Henan Business Daily that as long as there is enough food and a suitable place to enjoy the cool, the survival of verrucose swans in Zhengzhou is not a problem. "Verrucosa swans are wild species and should not be interfered with too much. We will monitor their situation at any time and solve them in time." Dong said.
