In our very first episode, we’ve got owls and turtles and bears, oh my! It’s all about animals.
But Why: A Podcast for Curious Kids is a show led by you. Kids ask questions and we find someone who can give you an answer. And that way all the rest of us listening get to learn something cool!
Our answer comes from naturalist Mary Holland. Her book is called, Naturally Curious.
"Black bears sleep all winter because they can sort of shut their bodies down. In late summer, before they go to sleep, they go on an eating binge. They eat, and eat and eat, lots and lots of plants and fruits and insects. They get fatter and fatter and fatter. Sometimes they even double their weight!
"When they get all big and fat, they find a den to sleep in. Sometimes it’s under a root or in the snow under a broken branch or sometimes they even sleep out in the open under evergreen trees.
"They slow down their bodies. Their hearts beat much slower. They breathe much less frequently. They take a breath almost every minute, much slower than normal.
"Once they go into hibernation they don’t eat, they don’t drink, they don’t pee and they don’t poop. They’re in hibernation four or five months, sometimes even longer. They have a plug in their butt that keeps them from going to the bathroom. When they wake up, in spring the plug comes out naturally and they start eating again."
"While they are sleeping, they are using up their fat. Those cells break down and provide them with water and calories. They also break down some of their muscle and organ tissues and those turn into protein to keep the bear alive.
"Female black bears give birth in January to tiny little cubs, two to five of them.
"They are not completely asleep, their sleep is quite shallow so that when the baby cubs need to nurse the mother wakes up and arranges herself so that the babies can get her milk. When the baby cubs nap, the mothers nap.
"The babies weigh about half a pound and are seven inches long when they are born, when the mother comes out of hibernation in April, the babies look like miniature adults. They can walk or climb, and eat some food, like green vegetation, but they are not completely weaned."
— Mary Holland, naturalist and author of Naturally Curious
