Chinese crested terns, one of the world's rarest seabird species, have been recorded in coastal wetlands in Nantong, east China's Jiangsu Province, for a seventh consecutive year.
Bird photographers captured images of the critically endangered birds on July 23 and 24, with sightings this season reported to be more frequent than in previous years.
With a global population of just over 200, the Chinese crested tern is under China's highest level of national protection. Its rarity and elusive nature have earned it the nickname "the mythical bird" in the country.
The species breeds mainly on uninhabited islands off the coasts of Zhejiang and Fujian provinces in east China. Between July and September, some birds stop in Nantong's coastal wetlands to rest and feed during their seasonal migration.
The repeated sightings underline the role of Nantong's wetlands as a stopover site for rare migratory birds, as Jiangsu continues efforts to restore wetland habitats.
