There is a day called Enlightenment in the calendar. This year, March 5 was the day of enlightenment. The word "enlightenment" means that insects that have been wintering in the ground feel the arrival of spring and crawl out to the ground. By the way, the brown bears of Bear Mountain have also tried to "stay in winter", and three months have passed at the earliest. Until now, the brown bears have been sleeping calmly on the straw, but recently they seem to be moving their bodies and somehow restless and soothing. It was March 5th when I started to feel such a thing. As usual, I went up to the roof of the brown bear house and counted my breathing rate, and I heard a metallic sound behind me. I had a similar experience last year, and I thought, "No way," and when I looked back, the lid of the ventilation vent started to move, and the bear's forelimbs came out. The youngest Santa, an 8-year-old male, stood up and opened the ventilation opening. Also, when observing the bear in the animal barn, I noticed the keeper and approached with a firm step in front of the door. It moves so well that it is hard to believe that it has slept without eating for three months, and I am once again amazed at the strength of the brown bear's vitality. On March 11, TV news reported that a wild brown bear appeared in a private house in Shari Town and ate "Takuan". From this news, I wondered if the time when wild brown bears and "artificial wintering" brown bears in captivity wake up at the same time. From this, if it is assumed that the completion of artificial wintering by brown bears in captivity coincides with the start of activity of wild brown bears, it may be possible to predict the activity of wild brown bears by looking at the movements of artificial wintering individuals, although it is a hypothesis. If you do so, I think it will be possible to inform those who are climbing in the spring or entering the mountains in advance of cautionary information. Bear Mountain is conducting an "artificial winter" with a large number of animals. The observation data may be used for various things [Breeding Kurokawa]
