The sanctuary is one of the smallest protected areas in India, covering less than 3 hectares.
It acts as a natural carbon sink, significantly impacting the air quality of central Kochi.
The site hosts a diverse range of mangrove flora which are rare to find in such high-density urban environments.
It is a prominent habitat for the Indian flying fox, a species of bat often seen roosting in the canopy.
The central lake is tidal, meaning water levels fluctuate based on the influence of the nearby Arabian Sea backwaters.
Mangalavanam Bird Sanctuary is a 2.74-hectare ecologically sensitive area known as the 'green lung' of Kochi. It is a protected bird sanctuary located in the heart of the city, serving as a critical nesting site for various resident and migratory avian species. The sanctuary features a shallow tidal lake connected to the backwaters through a canal system. Vegetation consists primarily of mangrove species such as Avicennia officinalis and Rhizophora mucronata. It serves as a vital roosting ground for little cormorants, black-crowned night herons, and little egrets. The area is managed by the Kerala Forest Department to preserve the fragile urban ecosystem. Despite its small size, it provides a habitat for small mammals, including the Indian flying fox and the painted bat.

Use high-quality insect repellent, as the humid mangrove environment is home to significant mosquito populations.
Bring binoculars, as the dense canopy and foliage can make bird spotting difficult with the naked eye.
Wear muted, non-reflective clothing to avoid alarming the sensitive bird populations.
Do not visit during the peak of the monsoon season, as the walking paths often become waterlogged and muddy.
Maintain silence to avoid disturbing the bird nesting sites; do not litter or feed the wildlife.
