Why Bird sanctuary?

Roughly 170 bird species have been recorded. Of these, the painted stork, Asian openbill stork, common spoonbill, woolly-necked stork, black-headed ibis, lesser whistling duck, Indian shag, stork-billed kingfisher, egret, cormorant, Oriental darter, spot-billed pelican and heron breed at Ranganathittu regularly.
During winter months, starting from mid-December, as many as 40,000 birds congregate at Ranganathittu, some migrating from Siberia, Latin America and parts of north Indi. During January and February, more than 30 species of migratory birds can be found in the sanctuary.

The problem faced by Ranganathittu:

The sanctuary with its islets experiences heavy flooding during certain rainy seasons when water is released from Krishna Raja Sagara dam upstream, due to heavy rains. During heavy flooding, boating is suspended and tourists are allowed to watch the nesting birds from a distance. Frequent flooding has also damaged some portions of three islands over the past few decades.
