One day, we were widely opening the door at the office because we couldn’t use an air conditioner for saving on electricity. Suddenly we heard something strange sound….and saw the floor unintentionally. Moving something near the desk. Wow, spot-billed duck (Anas poecilorhyncha) was walking the aisle! Mom was lead to one, two, EIGHT squabs!! When someone astonished and said “Oh!”, spot-billed ducks were also surprised and suddenly ran about this way and that in the office, then our office became the duck race stadium. In one hour, mother and her brood were captured and cheeped in the box. City hall’s officer took them to protect. I don’t know where they came from and why they entered in the office because there are no pond or river. There are only a road, houses, some restaurants and a public bath near the office. It’s the big mystery for me in this summer.
