SPARROW

The sparrow (চড়ুই) is a widespread bird species with 25 known varieties, two of which can be found in Bangladesh: the House Sparrow and the Eurasian Tree Sparrow. While most sparrows shy away from human interaction, the House Sparrow is unique in its ability to live in close proximity to humans while still maintaining its wild nature. This bird has become widespread, being one of only four species to reach a population of over a billion. The House Sparrow is typically 6 inches in length, with a brown and black plumage. Males have a distinguishable black “bib” on their chin that sets them apart from the females.

The House Sparrow has adapted to human environments, with its diet relying heavily on human activity. It feeds on leftover food and crumbs, as well as scavenging in garbage containers. For hygiene, the House Sparrow engages in sand bathing instead of water bathing, and does so in a social manner, often taking turns with other birds. In terms of reproduction, the bird has adapted by building its nests in hollow areas of buildings, such as roof overhangs and crevices.
