The International Waterbird Census (IWC) includes the Asian Waterbird Census (AWC). In 143 nations, the international census is undertaken.


Wetlands International and the Bombay Natural History Society are co-hosting the AWC. Every year in January, the AWC takes place. 
The volunteers count the waterbirds in the marshes during the census. Southeast Asia, Australasia, the East Asian – Australasian Flyway, and the region between Afghanistan and Japan are among the primary regions covered by the AWC. 
It all began in 1987. In 2021, the AWC recorded a fourfold decrease in the entire waterbird population compared to 2020.

Delhi’s Sanjay Lake

In the lake, just 13 species were found. There were 17 species documented between 2019 and 2021. 
The number of birds, on the other hand, has climbed from 90 in 2021 to 132 in 2022. The lake’s biological richness is dwindling. The lake is deteriorating as a result of this.
Cormorant and Eurasian Coot were among the migratory bird species seen in Sanjay Lake. The Cormorant is a migratory bird that originates in Southeast Asia. 
Temperate Asia is where the Eurasian Coot migrates. The India Spot-Billed duck is a common species in Indian wetlands. 
Only one pair, however, was discovered. The arrival of migratory birds in the lake has been reduced due to human pollution and boating. Water availability is also an issue for the lake.

Hastinapur Wildlife Sanctuary

It is located in Hastinapur, India. It is part of the Central Asian Flyway. According to the census, the number of bar-headed geese, common teal, and gadwall has decreased. 
The diversity of species has risen. The total number of bords spotted, on the other hand, has reduced. Human intervention is causing the lake to deteriorate.
The Census is still being conducted and is expected to be completed in February 2022.


Estimates of the bird population are needed.
To keep track of changes in the distribution of waterbirds
To gain a better understanding of waterbirds and to monitor waterbird habitat
To provide information on waterbird conservation.
To raise public awareness about the importance of wetland environments and waterbirds
Parts of Delhi are currently participating in the Asian Waterbird Census.
