Geese live in a great many habitats near lakes, rivers, ponds, or other small or large bodies of water, and in yards, park, and fields. In the spring, pairs break away from the flocks and begin defending territories with threatening displays, which may involve head pumping, hissing, honking, and vibrating of the neck feathers. The females select a nest site, builds the nest, and incubates eggs. Soon after hatching, goslings spend most of their time sleeping and feeding and often remain with their parents for their entire first year. As summer wanes, birds tend to become more social, gather in larger flocks. And with the approaching winter, they migrate shorter distances or not at all, even in extremely cold temperatures, depending upon open water and food resources.
