There is a day called Keichitsu in the calendar.

This year, March 5th was Keisei.

Keisei means that insects that have been hibernating underground for the winter sense the arrival of spring and come out to the surface.

Well, it's already been three months since Bear Mountain's brown bears tried to stay in winter.

Up until now, the brown bears have been sleeping peacefully on the straw, but recently they have been moving around a lot and seem to be restless and fidgety.

It was March 5th when I started feeling this way.

As I was counting my breathing on the roof of the brown bear house as usual, I heard a metallic sound behind me.

Having had a similar experience last year, I thought to myself, ``No way!'' When I turned around, the vent cover began to move and the bear's paws came out.

The youngest Santa (male, 8 years old) stood up and opened the vent.

Also, when observing the bear inside the animal enclosure, he noticed the keeper and approached the door with steady steps.

It's hard to believe that the bear has been sleeping for three months without eating, and I'm amazed once again at how strong the brown bear's vitality is.

On March 11th, TV news reported that a wild brown bear appeared at a private house in Shari Town and ate ``Takuan.''

This news made me wonder if wild brown bears and captive captive brown bears wake up around the same time.

Based on this, if the time when captive brown bears finish their artificial winter confinement is the same as the time when wild brown bears start their activities, it would be possible, hypothetically, to predict the activities of wild brown bears by looking at the movements of artificially wintered individuals. By doing so, I think it will be possible to provide warning information in advance to spring climbers and those entering the mountains.

Bear Mountain conducts "artificial winter confinement" for large numbers of animals.

The observation data may be used for various purposes.
