Most passerines are small, agile birds with strong feet. They are capable of beautiful singing and chirping. The most common is the house sparrow, which thrives in nearly all habitats and is a familiar sight in parks and gardens. The passerine family is the most diverse among birds, with over 6,500 species. More than 5,200 of these are songbirds, including the American goldfinch, the house finch, and the Carolina chickadee.

3. They Sing and Chirp

90-95% of all passerines love to sing and chirp. They enchant us with their lovely voices when courting a mate. All birds possess a vocal organ called the syrinx, located between the trachea and lungs. In sparrows, this organ is particularly flexible, enabling them to sing beautifully.
