Notes:
chestnut tiger アサギマダラ
—————————-
The autumn has been warm recently, so it is difficult to know what to wear. You can see some people in sweaters and jackets. Others are still wearing lighter clothes. The leaves on the trees in the city streets have started to change color, but they don’t seem as beautiful this year. The warm weather has also brought back butterflies. On a sunny day, you can see them flying around looking for flowers. Why are they still here? Some butterflies like the chestnut tiger fly south for the winter, but the butterflies we are seeing now usually sleep in winter. (by Prof. Douglas Jarrell)

Notes
Minnesota アメリカのミネソタ州;
ferment　発酵される;
—————————————
In a small town in the north of the United States, the birds have started acting strangely. This year, it got cold early in Minnesota. There was an early frost, and the berries on the trees started to ferment. The sugar in the berries turned to alcohol. Many birds eat these berries before they fly south for the winter. What happens to them? The alcohol makes them drunk. They can’t control themselves. Some birds fall out of trees and others fly into windows or cars. The police say that you shouldn’t worry if you see a drunk bird on the ground. It will wake up later and be fine. (by Douglas Jarrell)
