How is the House Sparrow Doing Now?

The good news is that though the House Sparrow has shown declines, with some interventions the populations seem to be rebounding.

In 2020, the first State of India’s birds report was released. This report is the first comprehensive look at how India’s birds are doing. There are over 1300 birds in India, and the report evaluated how both common and endangered Indian birds are doing. For this, it used a new tool: citizen science. 867 Indian birds were covered, by analysing 10 million observations uploaded by over 15,500 citizen scientists. Some of the records were current, and some were older, because birdwatchers were requested to share older bird lists.

The purpose was to understand how birds are doing currently and historically, in order to understand if they had declined, stayed at similar population thresholds, or increased. As per the findings of the report, 101 birds were listed as being of high conservation concern. Some of the birds that were considered common have had population declines. These include Cotton Teal, Short-toed Snake Eagle, Yellow-fronted Pied Woodpecker, the Indian Thick-knee, and Common Woodshrike. 

But it was also found that House sparrows are not doing too badly. The bird seems to be declining in metropolitan areas- with new buildings not providing traditional nesting areas, and an excess of pesticides killing insects that sparrow fledglings eat. But at the same time, in less built-up areas, sparrow populations appear stable. In areas within cities too, sparrows are returning wherever they are given chemical-free areas and nesting boxes.

How Can we Bring House Sparrows Back?

The decline of house sparrows points to the following things.

  • Overabundance and overuse of chemicals in our ecosystems and immediate environments, that kill insects which birds like House sparrows feed on. This ultimately poisons our own food chains. Thus, in order to control insects, we should use natural insecticides (like neem) rather than harsh chemicals. 
  • A loss of interaction between people and nature. House sparrows used mats on coolers to take nesting material. Houses built with traditional knowledge had cross-ventilation and open doors and windows. They were more indigenous, climate friendly, and sparrow friendly. Newer buildings have a lot of cement and glass facades. They take more energy to cool. Globally there is a movement to build more indigenous and sustainable housing. This means re-learning the cooling and building techniques of heritage architecture, the kind that sparrows used to nest in.

The Following Are Lessons in Bringing Back House Sparrows.

Firstly, using less chemicals in our life is generally a good way to reduce toxins in ecosystems. As insects come back to gardens, sparrows come back. Secondly, simple nests made out of shoe-boxes, waste material, pots, and wood are being used by sparrows in many cities. Thirdly, in our largely hot country, traditional architecture with locally sourced material should be used – not only does this reduce carbon footprints, but it will also bring nesting birds back. Finally, the case of the House Sparrow also reveals how important it is to study wildlife at a national level because this is an indicator of how the environment is doing.
