Why are sparrows disappearing?

Jeevan Sharma / nigrani Bureau । Bhangera is a Nepali word meaning “bird”. This word is especially used to refer to house sparrows found in Nepal. The sparrow is a small, usually gray bird with a white belly and black and white stripes on its wings.

It can be easily seen in rural and urban areas of Nepal. Sparrows like to live in groups and are often seen near human settlements. Sparrows usually survive by eating seeds, grains, small insects, and other food items. This bird builds its nest near people, especially in roofs, holes in walls, and trees.

The sparrow bird is also known as the “bird of the city” because of its close association with human settlements. A species of bird of brown color, as small as Kotero or Fisto, is called Bhangero. Its scientific name is Passer domesticus Linnaeus. In English it is called House Sparrow or Sparrow.

Sanskrit synonyms are Kalvinka, Kalakanthaka, Kulinga, Chatak, Pandavi, Potaki, Shakuni, Shyama and Shweta Pakshini. Properties of sparrow meat – Its meat is cooling, smooth, tasty, easy to digest, strong, spermatogenic, expectorant and Sanipat root destroyer. The meat of house sparrows is very spermatogenic. The meat of wild sparrows is easier to digest and nutritious than house sparrows. Although this is mentioned in Ayurveda, it is not suitable to eat the meat of this small bird for taste or to increase your meat.

World Sparrow Day has been celebrated since 2010 on March 20 to protect sparrows and raise public awareness about them. Sparrow Day is being celebrated every year in collaboration with various international organizations under the initiative of India’s Nature Forever Society. Sparrow Day has also been celebrated in Nepal since a few years ago. The slogan of this ye

a r’s sparrow day is that what is in sparrows. Since 2016, the Nepal Bird Conservation Association has been studying the birds found in urban areas in the Kathmandu Valley and found 1,000 to 1,500 house sparrows and 300 to 500 tree sparrows in 24 places in the valley. 

Nepal Bird Conservation Association has started to study the birds found in urban areas in Kathmandu Valley twice a year, in summer and winter since 2016. In the study conducted at 24 locations in Kathmandu valley divided into three parts – urban, urban and rural areas, the house sparrow is the third most common bird species and the tree sparrow is the sixth. In the five-year study, it is mentioned that 1,000 to 1,500 house sparrows and 300 to 500 tree sparrows were found in those 24 places in the valley. While the ongoing study will not predict future declines or increases in sparrows, its preliminary study has shown numbers to be stable over the past five years. Surprisingly, the number of house sparrows is higher in urban areas than in rural and urban areas. This could be due to the availability of suitable monasteries and food for sparrows in the city.

Among the 32 species of sparrows found in the world, only five types are found in Nepal, namely house sparrow, tree sparrow, black sparrow, Pitkanthe sparrow and Chitrapaj sparrow. Among these house and tree sparrows you prefer to live with people around our houses, settlements and karesabari. 
House sparrows mainly nest in man-made houses, buildings and monasteries, while the remaining three species mostly nest in trees. Chitrapaj Bhangera is a migratory species for Nepal. Eating spilled or scattered grains, eating some harmful insect larvae and larvae in grain crops, and the disappearance of sparrows in villages and cities due to the environmental health and balance around the house is a matter of concern and research in the field of nature conservation.
Since 2010, World Sparrow Day has been celebrated every year on March 20 to raise awareness for the conservation of the declining sparrow. The main objective of this day, which has been celebrated in Nepal since 2012, is to raise public awareness about the importance of sparrows, their condition, reasons for their decline, and public participation in conservation to ensure habitat and safe food.
  • The main cause of destruction

There are various reasons behind the decline in the number of sparrows. Here are the main reasons:

  • Loss of habitat: Urbanization and over-building have destroyed the sparrow’s natural habitats. Older house designs, which included places for nesting, are lacking in new construction Depletion of food sources: Excessive use of pesticides and other chemicals has reduced the number of insects, thereby reducing the sparrow’s main food source. In addition, changes in traditional farming systems have also affected sparrows.
  • Environmental Pollution: Pollution adversely affects the health of sparrows. Air, water, and noise pollution have negatively affected sparrow populations.
  • Mobile towers and radiation: Some studies have indicated that radiation from mobile towers can affect sparrow reproduction, leading to population declines.
  • Lack of food availability: The decline in traditional rice, wheat and other cereal crops in rural areas, and the lack of gardens and open spaces in urban areas have also made it difficult for sparrows to find food.
  • Loss of Biodiversity: Loss of biodiversity leads to an imbalance in the ecosystem, which can adversely affect the sparrow’s life cycle.

Conservation of sparrow populations requires measures such as reconstruction of habitats, reduction of pesticide use, conservation of biodiversity, and control of environmental pollution.
