The sparrow, especially the common house sparrow, is one of the most ubiquitous birds on earth and is also one of the oldest companions of human beings. It has, over a period of time, evolved with us. Fortunately, they are still found in abundance in many parts of the world.
The house sparrow was once the most common bird in the world, but in the past few years, this bird has been on the decline over much of its natural range, both in the urban and rural habitats. The decline of the house sparrow is an indicator of the continuous degradation the environment around us is facing. It is also a warning bell that alerts us about the possible detrimental effects on our health and wellbeing. We need to know the health risks of the increasing amount of microwave pollution and what is decimating the population of the house sparrow, which co-existed with us, so that we can estimate the effect on all forms of life, including ours.
The house sparrow also represents many of the common bird species and is, in a sense, their ambassador. Therefore, the conservation of the house sparrow and its habitat will also help save much of the common biodiversity, which shares the habitat of the house sparrows.
