The enzymes that act inside the small intestine are amylase, protease, and lipase. Amylase acts on starch and breaks it down into small carbohydrate molecules. Protease acts on proteins and breaks them down into amino acids. Lipase breaks down dietary fats into smaller molecules called fatty acids and glycerol.
Sandhill Cranes mate for life, choosing their partners based on dancing displays. Displaying birds stretch their wings, pump their heads, bow, and leap into the air. Although each female usually lays two eggs, only one nestling typically survives to fledge.
Sandhill cranes (Grus canadensis) are long-legged, long-necked, gray, heron-like birds with a patch of bald, red skin on top of their head. Cranes fly with necks outstretched like geese, whereas herons fly with necks tucked in on their backs.For positive identification, look for reddish skin on top of the crane's head.ranes are quite omnivorous feeding on seeds, grain, berries, insects, earthworms, mice, small birds, snakes, lizards, frogs, crayfish, but do not fish like herons. Resident sandhill cranes are usually seen in very small groups or pairs.
