Lesson IV

Eyes and Ears of Birds

Leading thought—The eyes and ears of birds are peculiar and very efficient.

Methods—The hen or chicken and the rooster should be observed for this lesson; notes may be made in the poultry yard or in the schoolroom when the birds are brought there for study.

Observations—1. Why does the hen turn her head first this side and that as she looks at you? Can she see an object with both eyes at once? Can she see well?

2. How many colors are there in a hen’s eye? Describe the pupil and the iris.

3. Does the hen wink as we do? Has she any eyelids?

4. Can you see the film lid? Does it come from above or below or the inner or outer corner? When do you see this film lid?

5. Where are the hen’s ears? How do they look? How can you tell where the rooster’s ears are?

6. Do you think the hen can see and hear well?
