As the north part of China endures the coldest days of the year, a large batch of migratory birds has started their trips to the south. Recently, however, a total of more than 3,000 world endangered migratory birds and first level national protective birds chose not to migrate to the south but stay in the Sino-Singapore Tianjin Eco-City in Binhai New Area to spend the winter.
Â
Taking up almost a quarter of the total existing number of species, such a large flock of gulls is extremely rare and has been seen in Tianjin for the first time.
Â
This kind of gull is a mid-sized aquatic bird, with a body length of around 40 centimetres. The head color of the gull is black in the summer, and looks like it is wearing a black scarf, while in the winter, their heads turn white.
Â
It is reported that the volunteers have found this kind of gull successively flying to the wetland in the eco-city to take rests and find food since the end of 2014. A bird protection expert explained that the arrival of large amounts of gulls in Tianjin is highly related to the premium ecological environment and the diversified wet land of Tianjin.
Â
The expert added that it is possible that more and more precious migratory birds will visit Tianjin in the future.
