Also called the house sparrow, domestic sparrow, etc. But 1 would personally term it as the nostalgic bird. It takes me back to when I was a kid. We (In India) would see these little fliers feed, nest, and play around everywhere. Sparrows were a common sight in the courtyard of almost every house in India, but now it is hardly visible. The number of sparrows decreases day by day, or id rather say they are not to be found anywhere now!
The sparrow's scientific name is Passer domesticus, weighing about 25-40 grams, standing 16 cm tall! And has a wingspan of about 21cm.

Rapidly changing cities are no longer a suitable habitat for the house sparrow, as the new and modern designs of infrastructure do not give any room for the sparrow to nest.
pollution caused by microwave towers and pesticides;
the house sparrow loses its foraging grounds (natural grasslands) as the green spaces in our cities give way to more concrete constructions.
According to the 2018 report from the Royal Society of London, the bond between humans and the sparrows is 11,000 years old. This study said that similar adaptation started through agriculture in three different species - dogs, domestic sparrows, and humans.
According to a recent survey done by the Royal Society for the Protection of Birds, the number of other significant birds has increased in the last 40 years, but it's utterly opposite with the sparrow; their numbers have decreased by 60% in India. There are about 26 species of sparrow worldwide, out of which five can be seen in India.
The 2015 bird census showed only 5692 sparrows in Lucknow and 775 sparrows in Punjab. Whereas In 2017, only 29 sparrows were observed in Thiruvananthapuram.
Sparrow plays an essential role in balancing the environment.
Sparrows feed their little ones with insects such as alpha and catworm.
These insects are hazardous for crops. They destroy the leaves of crops and destroy the crops as well.
Besides, sparrow eats insects that appear during monsoon season.
WWF-India has been involved in raising awareness about the declining population of house sparrows. Custommade nest boxes for sparrows are distributed in various states to encourage sparrow breeding. A special study was commissioned in 2007 on the status of sparrow population in Delhi.
