In recent days, one black concertina was recorded in Hainan Changgang Seatail National Wetlands Park. Experts at the Bird Records Centre in Hainan Province confirmed that this was the first time that the bird species had been recorded in Hainan Province.
Black concertinas are known to be a long-crowded waterbird with a similar appearance, mainly in freshwater lakes and rivers, occasionally at the entrance of mangrove swamps and tidal waves, preferring waters with scattered trees, forest margins or vegetation-intensive islands. The waterbird is now listed as an endangered species of the World Conservation Union Red List of Endangered Species, which is extremely rare in the country.
In this interview, which took place on the 13th day, the Black Concertary Recorder and Deputy Director of the Oceantail National Wetlands Park Centre of Heinnam, Xue Mei, described the rareness of black concertina in China, dating back to Fujian in 1931, after which no such species was recorded in the country for 90 years until 2021, when it was monitored in Yunnan. This was one of the few recorded in the country.
In Xue's view, the arrival of the "fruit" black cobra is an indirect recognition of the success of ecological conservation and restoration efforts in wetland parks in recent years.
The black cobra, which is a long-necked waterbird with a similar shape, eats mainly of fish and also of insects, aquatic reptiles and amphibians. Mainly inhabited by freshwater lakes and rivers, they occasionally appear in mangrove marshes and tidal estuaries, preferring the waters of scattered trees, forest margins or heavily vegetated islands.
To date, 213 species of birds have been recorded in Hainan Chang River Seatail National Wetlands Park, with a focus on 3 species of wildlife at the national level and 39 species of wildlife at the national level.
