Waterbirds of Jurong Lake Gardens
Waterbirds refer to birds that live on or around water. Many species have specialised adaptations like webbed feet, long legs and serrated bills for life in the wetlands. Waterbirds encompass many bird families including herons and egrets, shorebirds, ducks and rails to name a few. Listed here are some of the more commonly seen waterbirds in Jurong Lake Gardens.
Herons, Bitterns and Egrets
A varied group of birds found in both freshwater and coastal wetlands, they are carnivores that feed on a variety of aquatic prey and small animals. They differ from storks and cranes in their curved “S” shaped necks, which are retracted completely when flying.
