Tram chim: A flock of spot-billed pelicans (Pelecanus philippensis), a rare and endangered bird species, has reappeared in the Tram Chim National Park, located in the Mekong Delta of Dong Thap, after a six-year absence. The spot-billed pelican is listed in both the Vietnam Red Data Book and the IUCN Red List due to its declining global population. The species is identifiable by its grey legs, large body length of about 1.2-1.4 metres, webbed feet, and a long bill with a distinctive expandable throat pouch used to scoop fish. Pelicans typically live and feed in groups. Their return is considered a positive sign that ecological conditions in Tram Chim are gradually improving. According to Vietnam News Agency, Tram Chim National Park spans more than 7,313 hectares and is one of Vietnam's most important biodiversity sites. The park is home to 139 plant species, more than 250 species of waterbirds (including 22 rare species), 67 fish species, 174 phytoplankton species, and 110 zooplankton species. The reappearanc e of the spot-billed pelicans is a notable event for the park, highlighting its role as a sanctuary for various threatened and endangered species.
