Aquatic Wildlife Species of Bangalore

Bangalore was once a lake city, with around 1000 lakes spread across the city and outskirts. Today, there are only 80 lakes left, and with the diminishing of lakes, we have also lost our aquatic wildlife.

Bangalore is rich in urban wildlife, but over the years, this richness has been subsumed by urbanisation. Once a sprawling city for turtles, terrapins, fishes and migratory birds, the city now has very few habitats for aquatic wildlife. Let's explore some of the species which still call Bangalore their home!

Turtles

The most common species found in Bangalore is the Indian Pond Terrapin. We have rescued quite a few of them over the years. Their shells vary from reddish to dark brown and have black streaks. Next is the Indian Flapshell Turtle, with an olive green shell.

These species have been native to Bangalore for a long time. However, recent urbanisation is causing a lot of issues for their sustenance. Over the years, we have rescued turtles with broken shells, from conditions of dehydration, and confiscated a few from illegal trade.

There are also superstitions surrounding turtles which makes them more exposed to trading and illegal pet keeping. Until a few years back, people in famous temples used to buy turtles only to release them in small lakes or wells as turtles are believed to bring good fortune. They were being fed with vegetables, rice, and biscuits which shortened their lifespan.

People also buy turtles as exotic and status symbols. When they are unable to take care of them, they are released into lakes. Often, these turtles either do not survive or destroy the ecosystem of the lake.

Aquatic birds

Bangalore is home to many water birds like herons and storks. A lot of these birds are migratory and visit our city during winters. Over the years, we have rescued herons, storks, kites, and pelicans. Some of these were found dehydrated, and some came to us with injuries.

The Black Headed Ibis is found in South and Southeast Asia. They have a large white body and a black head and neck. They feed on insects, larva and fish, and thus maintain the health of the lake.

The Little Grebe is another aquatic bird which lives in lakes. They are skittish in nature and hide as soon as someone comes near. They are excellent at keeping themselves out of sight! They are very active during the night.

The Night Heron is another bird found in Bangalore. They have thick necks, large, flat heads, and heavy, pointed bills. The legs are short and, in flight, barely reach the end of the tail. They feed on fish, frogs, snakes, and carrion.

A report published by Deccan Herald in October, 2021 talks about the importance of lake rejuvenation projects. A study conducted around the aquatic birds revealed that as a result of lake rejuvenation projects, the native water birds such as painted storks, pelicans, cormorants, Brahminy kites and egrets are thriving!

The study also concluded that lakes which were further from the city center have richer habitats. Unfortunately, the population of migratory birds has reduced over the years, and is likely because of urbanisation in the whole country.

It is of paramount importance to keep the lakes clean and habitable for our rich aquatic wildlife. Lake rejuvenation projects are proving to be successful and there is a need to support and fund more such endeavours. Decline in lakes will eventually lead to imbalance in the ecosystem, which can cause drought, uneven monsoons, and lack of drinking water. As long as our aquatic wildlife is in peace, we will be in peace too!
