The Jiuduansha Wetland Nature Reserve in Shanghai recently set a record for the number of Dalmatian pelicans (Pelecanus crispus), one of the world's largest freshwater birds, according to the Shanghai Landscaping and City Appearance Administrative Bureau.

Located only a few kilometers from Shanghai Pudong International Airport, Jiuduansha is one of the city's few remaining natural wetlands. Known as "the last virgin land in Shanghai", it sits at the mouth of the Yangtze River and is a haven for migratory birds.

On Feb 14, surveyors from the reserve recorded an impressive 26 Dalmatian pelicans, classified as a national first-class protected wild animal. This is the highest number of such birds to ever be sighted at the reserve since its establishment in 2000.

When the pelicans were spotted, they were flying in formation toward the survey team's boat, creating the impression of an aerial parade.

This followed previous sightings of 13 individuals on Jan 13 and four on Jan 22.

Dalmatian pelicans typically measure between 1.6 and 1.8 meters in length, with a wingspan exceeding 3 meters and a weight of up to 15 kilograms.

The latest research estimates that the population of Dalmatian pelicans overwintering in southeastern China is just over 160 individuals.

The recent large-scale sightings at Jiuduansha suggest that the reserve's pristine environment, with abundant food and minimal human disturbance, provides an ideal habitat for these birds to rest and forage, according to the bureau.
