context_page_description: Passer is a genus of sparrows, also known as the true sparrows. The genus includes the house sparrow and the Eurasian tree sparrow, two of the most common birds in the world. They are small birds with thick bills for eating seeds, and are mostly coloured grey or brown. Native to the Old World, some species have been introduced throughout the world.
context_section_description: These sparrows are plump little brown or greyish birds, often with black, yellow or white markings. Typically 10–20 centimetres (3.9–7.9 in) long, they range in size from the chestnut sparrow (Passer eminibey), at 11.4 centimetres (4.5 in) and 13.4 grams (0.47 oz), to the parrot-billed sparrow (Passer gongonensis), at 18 centimetres (7.1 in) and 42 grams (1.5 oz). They have strong, stubby conical beaks with decurved culmens and blunter tips. All species have calls similar to the house sparrow's chirrup or tschilp call, and some, though not the house sparrow, have elaborate songs.
