Due to the rapid urbanization, it has been observed that the number of sparrows has been decreasing for some years. As concrete houses are being built in place of old houses, the habitat of sparrows is disappearing. When you hear the chirping of sparrows, you know it's morning.

Sparrows were seen playing and enjoying in the yard. Now all that has passed," said Dahit, a resident of Shuklaphanta Municipality-3, "Now you don't hear the chirping sound of sparrows, nor do they come to eat the biscuits in the yard like before."

He says that sparrows are seen only by surprise. He considers the rapid urbanization as the cause of sparrow destruction. He says that it is natural for sparrows to decrease in number as there is no place to nest. He says that the declining number of sparrows is a matter of concern.

According to ornithologist Hirulal Dagoura, the radiation coming out from mobile phone towers affects the sparrow's direction finding system. Fertility is adversely affected. It has also been found that sparrows die when radiation affects the brain. 'Sound pollution also affects sparrows,' he said, 'sparrows die when farmers use pesticides excessively in the fields.'

He said that sparrows are also getting less food because they are dying due to pesticides in the fields. According to him, there is a decrease in the number of sparrows because crows, cats and other predatory birds prey on them. According to him, sparrows are important for biodiversity and ecosystems. Arrangements should be made to nest in houses to protect sparrows. We can protect the sparrows by doing small things such as arranging the grains and water on the roof along with creating a nesting environment.
