Sparrows, today there is 30 species of sparrows. Sparrows are omnivores they eat mostly seeds and insects. Mostly sparrows live near houses or on the roof of buildings. They are about 11-18 cm long and weigh 13-42. Sparrows are usually gray or brown. They sing songs to each other but I don’t know how they talk normally. They do not migrate at all they will only move a few kilometers in their lifetime. Sparrow eggs are small. Sparrows will lay 3 to 7 eggs but commonly 4 to 5 eggs.
