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.
Based on past research, approximately 90% of the nest will contain 2 eggs, 9% will contain 1 egg and 1% will contain 3 eggs. Eggs average 100 mm in length and 63 mm in width. Whooping crane pairs share in incubation of the eggs.Incubation lasts from 29 to 31 days.ortunately, egg predation is uncommon, and re-nesting by whooping cranes is believed to be rare. So, normally whooping cranes usually produce clutches of 2 eggs laid 48 to 60 hours apart. Incubation begins with the first egg laid. Therefore, hatching of the eggs does not occur at the same time.
