Meet the rat control brigade

These birds help you keep the rat population under control. And yet they are considered to bring ill luck.

We have a lot of birds around us in the city. Some eat seeds, some fruits and some eat live prey. We’ve all seen sparrows pecking at the grain in the market areas, or seen parakeets pecking at ripe fruit…but some birds are predators.

Even in the city, we have several predators; the most common, of course, is the crow, which will often raid the nests of other birds to eat up their eggs. But there are two common birds that actually help human beings in our city….and at least one does not deserve the bad reputation it has.

Here’s the Barn Owl. It often roosts and nests in groups near apartment buildings, or homes with gardens. For some reason, it is traditionally considered a bird of ill omen. A valid reason that many people don’t like them is that they often bring dead rats and mice, and make a very disturbing “chirring” noise all night. But have we considered why the dead rats and mice are there?

Our urban lifestyle generates a lot of trash, much of it food waste. And rodents – rats, mice, bandicoots, thrive on this trash. They live in the underground and open sewers of our city, and since many of them are rabid, they propogate disease, too.

When the population of rodents increases, Nature’s way of maintaining the balance is to get birds like the Barn Owls to the spot! These birds, which are active at night, prey upon the rodents, and actually help us stem the rising rodent population. So, they should be thought of as good omens, not bad!

Several Barn Owls hunt around my building and I love watching their noiseless flight as they swoop down upon their prey!

Another bird that controls rodents is the Shikra.

Shikras are one of the raptors that are smaller in size. They have the typical hooked beaks and sharp claws that birds of prey have. They are active at dawn or dusk, but can sometimes be seen in daylight, also, sitting quietly on the branch of a tree, or any other roost where they feel comfortable.

So…when going for a walk, especially at dawn or dusk…do look around and see if you can spot these members of the Rat Control Brigade! Yes, both of them are fairly common in Bangalore.⊕

Explained: How Mumbai is losing its tree cover to infrastructure projects

Mumbai's landscape is changing with big infra projects. Experts suggest better use of government plots and improved street design to retain green cover.

Long before Mumbai’s relentless summer even began this year, the city was already simmering. In March, Mumbai was hit by a severe heatwave, with the temperature reaching a five-year high of 40° Celsius. As rapid urbanisation and a flurry of infrastructure projects replace dense tree cover with steel and mortar, heatwaves seem to have gone from being rare occurrences to an annual threat.   The Mumbai Metro Rail Corporation Limited (MMRCL) cut a whopping 3,093 trees in Aarey Colony to make way for Mumbai’s Aqua Line ( Metro 3). For environmentalist Stalin Dayanand, this is not just a temporary problem.…

Notes from the field: Why Begur Lake is losing its waterbirds

71% of waterbirds at Begur Lake are declining. A visit to one of Bengaluru’s rapidly deteriorating lakes shows what's causing the collapse.

During the Open City biodiversity datajam held in December 2025, our group examined the ecological trends around Bengaluru’s lakes. Our analysis suggests a majority of waterbirds are declining across the city's lakes. Earlier, we addressed crucial questions on how migrant and resident waterbirds are surviving across 14 of Bengaluru’s lakes, how the shape of the lakes influence microhabitats, and how a scoring system can be used to record the decline in lake quality and bird populations. The last of our four-part series turns its attention to an individual site. As part of this study of waterbirds in 14 city lakes,…
