I think volunteer work is more common in the US than Japan. There are many opportunities and people are willing to work as volunteers here, in the US. That is great!
So I also started volunteer. Since I like wildlife, I work at a bird center as a volunteer. At the center, we take care of wild birds that are injured or orphaned. I go to the center every week and I feed baby birds and clean cages. We have to feed them every 30 minutes! They are noisy but so cute. They are waiting for food with their mouths open. There are many kinds of birds including sparrows, finches, doves, blue jays, robins and geese. All those birds are brought by kind people who found a bird that cannot survive in the wild. There are about 100 birds at the center at a time, and a few hundreds birds during a entire summer season. After we take care of the birds and they become big and healthy, they are released into the wild again. That is happy and sad moment.
I like this work.
