The Kolleru wetland ecosystem provides valuable habitat for a wide variety of birds. During the migratory season, the area becomes particularly attractive to birdwatchers as numerous waterbirds and other species gather around the lake and wetlands.

The sanctuary landscape combines shallow waters, marshes, vegetation and open wetland areas, creating an excellent environment for observing birds in their natural surroundings.

Birdwatching enthusiasts can look for a variety of waterbirds, including pelicans, painted storks, herons, egrets, ibises and other wetland species, depending on season and local conditions.

Kolleru is especially suitable for eco-tourism, bird photography, nature education and wildlife awareness. It is an excellent destination to showcase Andhra Pradesh's lesser-known natural heritage.
