Happy Canada Day!
This one’s for all of our Canadian followers, celebrating Canada Day by examining the national animal, the Bibarel!
Well, the national animal is a beaver, but Bibarel is also a large dam-building semi-aquatic rodent. But yeah, beavers are totally unique in the way the build and manipulate their environments, second only to humans.
Beavers build homes in water, called lodges, out of wood. Their homes dam up water and can be absolutely gigantic. The largest ever recorded (850 meters) could be seen from space. They have a very particular method of construction, using their teeth (which never stop growing) to knock down and cut up trees to use in their lodges. Larger trees form the base of the dam near the bottom, and smaller trees fill in the rest, as well as provide the most food. They build all year round, not even stopping during the winter. The entrance to their home is underwater, and a dam usually consists of two dens: one for drying off, and one for living and socializing with their family.
Bibarel are very good swimmers, reaching speeds of about 5 miles an hour with their webbed feet and using their unique tails to steer. They can hold their breath for over 15 minutes and have a special pair of transparent eyelids, which act like goggles to help them see underwater.
Bibarel are industrious workers which build underwater nests out of trees they chop down with their teeth.
If there’s any upcoming holidays you’d like us to celebrate, let us know!
