Delhi Zoo conducted a census of its aquatic birds on Wednesday, documenting them across five water bodies within the premises and categorising them into 10 groups, officials said.
The “Asian Water Bird Census 2025” recorded 609 birds representing 19 species, they added.
Conducted from 10 am to 12.30 pm, the census was carried out in partnership with ecologist and conservationist T.K. Roy, along with volunteers from educational institutions, universities, and NGOs, according to a statement.
Among the key findings were 382 painted storks, the highest count for any single species, along with 58 Indian cormorants and 41 great white pelicans, the statement noted.

Other species observed included the little grebe, grey heron, and red-wattled lapwing.
The census underscored the zoo’s role as a vital habitat for both migratory and resident water birds, the statement highlighted.
Bird groups such as herons, egrets, ducks, plovers, and kingfishers were also documented, with experts stressing the importance of conserving urban biodiversity hubs.
Meanwhile, the National Zoological Park (Delhi Zoo) has introduced a range of measures to safeguard its animal residents.
As part of a comprehensive winter management plan, the zoo has adopted eco-friendly practices, such as replacing diesel vehicles with cleaner alternatives and using fogger machines to spray water and suppress airborne dust, particularly in pollution-prone areas.
Located in a relatively lower-lying area, the zoo benefits from some natural protection against pollution.
In addition to combating air pollution, the zoo has revamped its winter care practices to ensure the comfort of its animals while minimising environmental harm. Previously relying on firewood for heating enclosures, the zoo has switched to non-polluting heaters and uses stubble as bedding, simultaneously providing warmth for animals and addressing pollution caused by stubble burning.
