Whether it is a nest of grass or an elaborately woven home, these animals feel at home in houses of their own making!
We build ourselves many different types of houses, but Nature provides a great variety of housing for Her creatures, too! Let’s look at some of the smaller beings…
Here’s a Weaver Ants’ nest; the ants “weave” together the leaves with a paste that they generate, and make a water-proof home. Pic: Deepa Mohan
Here are two Paper Wasps, beginning the construction of their nest (yes, it is a kind of papery material, hence their name. Pic: Deepa Mohan
When they finish, the wasps’ nest looks like this… such a beautiful globe, with its crescent-shaped patterns. However, do not approach too
close, for fear of being stung! Pic: Deepa Mohan
Several birds do much more than stack twigs together; one of the most famous “architects” is the Baya Weaver, Here is a male Baya Weaver (it’s the males who build the nest…the females inspect them, and if they are not good enough, they don’t accept!) weaving the nest
expertly. Pic: Deepa Mohan
Another very common bird is the Tailorbird. When you see the nest of a Tailorbird, it’s obvious why it’s called that. Can you see the neat
“stitching” of the leaf and the nest material, in this photograph? Pic: Deepa Mohan
Here are two Grey Tits (I often see them in the Bannerghatta zoo area)… these two are actually checking out an old “junction box” left by humans, to see if it is fit to nest in! So what we leave behind is
sometimes useful to birds, too. Pic: Deepa Mohan
Even the most “fearsome” of creatures need the protection of a nest, sometimes. Here is the nest of an Indian Tarantula…. females which
have just-hatched eggs spin this “silk screen” in front of their holes, to prevent predators such as wasps and ants from coming in! Pic: Deepa Mohan
High-density traffic corridors and industrial hubs cause PM2.5 pollution in localised hotspots of Bengaluru.
Hazy mornings with the air thickened by vehicular smoke during peak-hour traffic are synonymous with Bengaluru winters. The city may have lower PM2.5 levels overall when compared to other mega cities, but high-density traffic corridors and emissions in industrial hubs are causing localised pollution spikes. A November 2024 study by Respirer Living Sciences, analysing PM2.5 pollution levels across ten Indian cities, revealed this data. The study examined AQI information from 13 Continuous Ambient Air Quality Monitoring (CAAQM) sites in Bengaluru that recorded an average of 39 micrograms per cubic metre (µg/m3) of PM2.5 air pollutants in November 2024. This is…
In Part II of our ongoing series on lake systems, we look at the 'assets' that make these complex ecosystems sustainable, and the role of each.
A lake is much more than a mere water body, it is a complex ecosystem. All those resources or features that make this ecosystem complete and sustainable can be considered lake assets. Assets are generally classified into core zone assets (ecological zone assets) and social zone assets (recreational zone assets). Each serves a set of distinct purposes, supporting the ecological, infrastructural and social functions of a lake system. Here is an overview of the kind of assets that come under each category and the role they play in the lake ecosystem: Core zone assets (Ecological zone assets) These assets are…
