As we entered the end of January and the cold was getting more severe day by day, I thought that all the bears in Bear Mountain were sleeping quietly, but there was one bear that was still restless (>). <) This is "Moko", which joined the ranks of Bear Mountain last fall. Moko is a bear that has never experienced winter sleeping, and she has not eaten anything for a month due to fasting for winter, so she needs to be very careful about managing her physical condition. This morning, he opened the lid of the ventilation vent on the roof with his forelimbs and appealed to us. This is something that bears often do when they have begun to wake up from winter slumber in early spring to appeal to them, but it is troublesome and very worrying to make this appeal at this time of year in the height of winter. As an aside, bears that are sleeping in winter store a lot of nutrients in their bodies in the fall, so if they are quiet, they can live without eating anything until spring, but they do not need water to sustain their lives. At Bear Mountain, we secure moisture by giving ice to bears that are sleeping in the winter, but it is also important to make ice to secure that moisture. Thanks to the recent cold weather, ice is forming more and more, and while I am grateful for the winter nature of Hokkaido, I continue to fight the cold every day. 【Breeding, Shigematsu】
