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.
There are six subspecies of sandhill cranes; three migrate, three do not. The lesser sandhill crane is the most numerous subspecies and the most common crane in the Platte River area. In fact, 80-90 percent of the worldâs population migrates through the region.andhill cranes do not reach sexual maturity until they are 3 to 5 years old; in the wild they can live to be more than 25 years old. Once on their nesting grounds, the pair builds a ground nest and the female lays two eggs.
