This is a young or possibly juvenile bird, and based on the physical characteristics visible in the image — such as its small size, short beak, and brown-grayish plumage — it looks like a sparrow chick, likely a house sparrow (Passer domesticus), which is very common in many parts of the world, including South Asia. A few details: Species: Likely House Sparrow Age: Juvenile (still has soft, fluffy feathers and appears slightly wet or just ruffled, suggesting recent rain or possibly having fallen from a nest) Habitat: Sparrows are commonly found around human settlements — they nest in buildings, under roofs, or in small cavities. Diet: Seeds, grains, and small insects — young ones are usually fed insects by their parents.
