		The Trip to Bald Eagles’ World

	Narrator:	An instructor and his assistant take two students to the national museum to tour the bald eagles’ section of the museum.
	Setting:	Entrance to the national bird museum
	Instructor:	Today’s trip to this national bird museum is to give you a better understanding about the bald eagles. Remember to stay together as a group.
	Assistant:	Please prepare to take notes as we walk through the bald eagle section since a majority of today’s lesson will be on the final exam.
	Setting:	In the bald eagle section of the national bird museum
	Instructor:	Let's begin with something interesting. Who can tell me why bald eagles are called "bald eagles"?
	Student A:	Because they are bald!
	Student B:	That is wrong! Bald eagles are not really bald. Bald comes from the word “balde” (B-A-L-D-E), an Old English word, meaning white. Bald eagles were named for their white feathers instead for the lack of feathers.
	Assistant:	That is correct!
	Instructor:	A bald eagle's body consists of a blackish- brown back and breast; a white head, neck, and tail; and yellow feet and bill.
	Student B:	Is the male bald eagle bigger than the female in terms of size?
	Student A:	Of course it is, males are supposed to be bigger and stronger than females.
	Assistant:	Again, you’re wrong! Female bald eagles are slightly larger than male bald eagles.
	Instructor:	An eagle's wings are long and broad, making them effective soaring. Soaring enables the eagles to conserve energy.
	Assistant:	Who can tell me how many feathers does a bald eagle have?
	Student A:	five! One for the head, one for the body, two for the wings, and one for the tail!
	Instructor:	Now stop fooling around. Bald eagles have about seven thousand feathers. They are lightweight yet extremely strong and highly flexible.
	Assistant:	They also protect the bird from the cold as well as the heat of the sun, by trapping layers of air.
	Student B:	What are the eagle’s talons used for?
	Student A:	This I know. Talons are important tools for hunting and defense. Bald eagles kill their prey by puncturing its flesh with their talons.
	Instructor:	That is very good. Let's continue to the diet and feeding habits of bald eagles.
	Assistant:	Bald eagles feed mainly on fish. Their lifting power is about four pounds or about kilograms.
	Student B:	Teacher, how does a bald eagle eat its prey?
	Instructor:	Good question. First, the eagle holds its prey with one talon, and the other onto its perch. Finally, it tears off each bite with its break.
	Student A:	And did you know that a bald eagle can consume one pound of fish in about four minutes.
	Student B:	What?! Are you serious?
	Assistant:	As Yes, that’s true. This is how strong a bald eagle is.
	Instructor:	It's about time to leave now. Before we leave, let's have a trivia question. The person who anwer correctly will get bonus points. The question is "can bald eagles swim"?
	Student B:	So easy! Of course not, bald eagles fly, not swim!
	Student A:	I think bald eagles can swim.
	Instructor:	The correct answer is "yes". They swim by using and overhand movement of the wings similar to the butterfly stroke. Ok, that's it for today's lesson. See you tomorrow.
