Major Fact: Brilliant Burrows

Marmots live in places that are cold and even frozen for long periods, so they spend most of their life sleeping through it. 

Marmots spend 80% of their lives asleep and 60% is in hibernation. To sleep that much, you have to have an excellent bedroom. 

Marmots live in daily burrows that can be three feet deep and up to 50 feet long. During the winter, their hibernation burrows can be as deep as 23 feet (7 m). In the spring and summer, they are most active during the day, but they take siestas at noon to avoid the heat of the day.

If you’d like to visit one today, you’ll have to come back later. They start to hibernate around September and sleep all the way to May. 

Two-year-old males that emerge from their burrows in the spring immediately start digging their own burrows to prepare for mating season. A great burrow can earn the male marmot many maidens. They mate with two or three females each year. When pups reach a year old, the male will vacate the family burrow but stick close to the area to defend one or two of the females and their pups. 

Ending: So whistle if you hear danger, sleep as much as you can, and dig a tunnel dig dig a tunnel like the marmot here in LDT.
