Passeridae is a family of small birds commonly known as sparrows. This family includes various species, such as the house sparrow and the tree sparrow, which are found in diverse habitats around the world. They are characterized by their stout bodies, short tails, and conical beaks, which are well-suited for seed eating. These birds are social creatures, often seen in flocks, and they typically build nests in trees, shrubs, or human-made structures. Passeridae plays an important role in ecosystems by helping with seed dispersal and controlling insect populations. Their adaptability has allowed them to thrive in urban environments.
