Scientific name: Passer domesticus
From an introduction into New York City, the adaptable House Sparrow has expanded to occupy most of the coterminous U.S. and southern Canada. A diet of grains and weed seeds, and a tolerance for close human habitation have contributed to the House Sparrow’s success.
Very social in nature, House Sparrows occur in flocks during the winter, and even nest close together, defending only a small area immediately around their nest. Males chase other males away from the nest, and females chase other females away.
