CANADA GOOSE (Branta canadensis) Among the sights and sounds of nature few are as hauntingly beautiful as a honking flock of wild geese silhouetted against a crisp autumn sky. Although the species is usually migratory, many Canada geese spend the entire winter in Yellowstone and Grand Teton. Courtship of both migra- tory and non-migratory birds usually begins in April. Canada geese mate for life, and both male and female share the responsibility of caring for the nest and young. During the incubation period the gander guards the female on the nest and aggressively drives intruders, including coyotes and even humans, away from the nest. Once the goslings hatch, geese feed on the shore or in open fields within commuting distance of the water. Geese graze, plucking up grass and other vegetation, or they collect food from the bottom of a stream or lake. Large numbers of Canada geese summer in Yellowstone's Hayden Valley, and at Oxbow Bend in Grand Teton, and the species is generally common on lakes and rivers of both Mallard Bruce Pitcher GREEN-WINGED TEAL (Anas carolinensis) In the shallow water of small lakes, ponds, and streams, and in marshy areas where small streams wander aimlessly through the tall grasses, the green-winged teal floats silently or turns bottoms up in search of aquatic plants and insects. Although this teal is primarily a surface-feeder, it can dive effectively if the occasion demands. Green-winged teals frequently leave the water and travel long distances in search of food. When flushed, the teal explodes from the water without the aid of a running takeoff. The flight of the teal is swift and direct, but often features unpredictable twisting and turning maneuvers. The smallest of Yellowstone and Grand Teton ducks, the green-winged teal is a common breeding bird, and an occasional winter resident in both parks. 20.
