Mangalavanam Bird Sanctuary, the “green lung of Kochi,” is an ecologically sensitive area behind the Kerala High Court in Kochi. A haven for birdwatchers, it hosts a diverse array of migratory and resident birds. A 2006 survey recorded 194 birds across 32 species. The sanctuary is also rich in flora, including endangered mangrove species like Acanthus ilicifolius and vulnerable Rhizophora mucronata.
