The wings of birds.—Describe the different kinds, as short and round, or long and slender, and the effect of the wing-shape upon the bird's motion in the air. Describe the flights of different birds.

Songs of birds.—Write the syllables which seem to you to express the different songs of birds. Notice the different songs of the same bird. A song sparrow was observed to have twelve different songs. He sang each one several times over, as if each song had a number of verses. Then changing his position, he would sing another. To most ears the robin's song is always the same, but close attention discovers that there are variations. Many birds are genuine musicians and compose as they sing, not having formal songs.
