The snow goose's habitat, anatomy and behavior are shown in the first section of this program. It explains the ability of the snow goose to migrate, using its own 'navigation system' and details the bird's pulmonary system. The Great Blue Heron's anatomy begins the second section of this program. To fish for its prey the heron has the ability to stand still, while its eyes can move to search for prey. It also moves about or 'prowls' for fish. The heron's skeletal structure keeps it stable. The third section of this program details the egret's behavior and gives a comparison of the Cattle Egret's and the Snowy Egret's habitat and anatomy. The Egret's bone structure shows the ability of this bird to fly.
