Mangalavanam, a nesting ground for a large variety of migratory birds, is a paradise for birdwatchers. This green paradise is also a roosting place for resident as well as migratory birds. A survey conducted in 2006 revealed that there were 194 birds belonging to 32 species in Mangalavanam. It is an ecologically sensitive area situated at the centre of Kochi behind the Kerala High Court building, fittingly dubbed as the 'green lung of Kochi'. Primarily a bird refuge, the innate appeal of Mangalavanam is augmented by the Arabian Sea which borders the sanctuary and adds to it a panoramic ambience.
