The summer solar term in the twenty-four solar terms is approaching. At this time of year, many migratory birds leave northern China one after another and fly to the south; next spring, they will return as scheduled. They go back and forth every year, and this migration behavior can be called one of the most magnificent "fan dramas" in nature. Recently, summer migratory bird’s "vanguard"- gray-headed wheat chicken "comes" to Suzhou, where they search for food, trim and replenish their energy for the next "all the way to the south". Departure, also officially kicked off this year's migratory bird migration.
Today, the brand column "Twenty-Four Interests" of the Suzhou newspaper brand column, Zheng Wei, a special teacher and bird survey expert of the Solar Terms Nature School, told reporters that he and the Suzhou Forestry Society Fan Ruyu and Wu Xiaodan two days ago A bird survey expert observed a cluster of gray-headed wheat chickens migrating along the Yangtze River along the Yangtze River at Baimaokou in Taicang City. The number is as high as 1,910. This is the first group of migratory birds that Suzhou has ushered in. They rest, feed, and adjust to the best The state set off again. It is understood that the gray-headed wheat fowl is a bird belonging to the genus Alyssaidae of the Ploveridae family, and is a global non-dangerous bird species. "Grey-headed wheat chickens are good at flying, often turning up and down in the air, flying slowly, flapping their wings slowly, and flying at a low altitude. Sometimes they inhabit water or grass. When people approach, they stretch their necks and watch. If there is danger, take off immediately." Zheng Wei said, and the number of observations this time is the largest number of single observations in the history of Suzhou.
Why do the nearly two thousand gray-headed wheat chickens appear in groups on the lawns along the river? Zheng Wei told reporters that most of the gray-headed wheat chicken breeds in northeastern China and Japan, and moves south to India and the Philippines in autumn and winter. There are also a small number of breeding populations in Suzhou. "The gray-headed wheat chicken is the early bird migration, and their migration heralds the opening of the migratory bird migration scene.Zheng Wei said that this time nearly 2,000 gray-headed wheat chickens passed the Taicang area along the river, which is not accidental. It is an important habitat and'transit station' for birds. A large number of migratory birds pass by and stop here every year. The wetlands and green spaces along the river are of great significance to migratory birds, just like the gray-headed wheat chickens will continue to migrate south after foraging and resting here every year.
Like the gray-headed wheat chicken, many migratory birds will choose Suzhou, which has a good ecological environment and sufficient food, as the "transit station" of the "Long March". Observation data show that in recent years, the Suzhou area has observed There are 312 species of migratory birds, including house swallow, golden-waisted swallow, pond heron, cattle egret, grey-headed wheat chicken, water pheasant and summer migratory birds, Winter migratory birds such as blue-headed pochard, cygnets, coot chicken, ribbed duck, carduelis, and chaffinch are the main winter migratory birds, and sometimes transit birds such as plovers will stay for a short time. "In recent years, Suzhou City has been active. Carrying out the Party Central Committee's policy of “to protect the Yangtze River and not to engage in large-scale development” policy, the ecological protection work along the Yangtze River has been strengthened, and through continuous deepening of protection and scientific protection, more birds can be “visited” in Suzhou. Zheng Wei said.
It is reported that the bird survey experts also simultaneously observed and recorded 740 cattle egrets, 66 golden plover and 1 national secondary protected animal on the same day. ——Little Snipe, 2 National Class II protected animals—— Kestrel,And large flocks of migratory birds such as house swallows and golden waist swallows.
