House sparrows are often found in urban areas, where they thrive in close proximity to humans, making them one of the most familiar bird species worldwide. These birds are social creatures, often seen in flocks. They build nests in various locations, including buildings and trees. The house sparrow's adaptability to different environments and its ability to exploit human resources have contributed to its widespread distribution across the globe.
