Beavers

October 22, 2018

Walking on gravel in the dark, I was doing my best to not make any noise. I could kind-of-see where I was going but when you are carrying heavy and expensive camera gear and tripod, you always want to be extra careful. Approaching the edge of the clear-water pond, I sat down and started to organize all of the camera gear.

Thank goodness I was wearing my waterproof overalls. The ground at the edge of the pond was wet and muddy. My feet were resting in 2 to 3 inches of water, so I was also happy I had on my waterproof boots. Recent rains soaked the landscape and swelled the rivers.

Even though it was late summer, the morning temperatures in northern Alaska were in the low 40’s. Two layers of clothing and a winter hat and gloves were essential, especially when sitting for long periods of time.

It didn’t take long before I could see some movement on the opposite side of the pond. Coming out of the darkness, cutting through the glass-flat water, I could see a large branch with many leaves moving in my direction. Yes, that’s right, a branch with leaves was moving through the water.

As the branch got closer I could finally see what was moving the branch. An adult beaver was swimming in the pond bringing breakfast home to the family.

Beavers are one of my favorite critters. The North American Beaver, usually just called Beaver, is only one of two beaver species in the world. It’s native to North America but has been introduced to South America and also parts of Europe. It is the official symbol of Canada and the official mammal of the state of Oregon.

The beaver is the largest rodent species in North America and the second largest in the world. Adult beavers weigh from 25-70 pounds with the average adult beaver weighing about 40 pounds. They are semiaquatic animals that is very well suited for life in the water. It has a second eyelid that closes to protect the eye when swimming underwater but still allows the beaver to see. They have waterproof flaps that cover their nostrils and ears when submerged.

They have large webbed hind feet that propel them through the water but their front feet are unwebbed with five moveable fingers and sharp claws. Of course everyone knows about their large flat, paddle-shaped tail. By the way, they don’t use their tail to pat down or shape their stick and mud dams.

For five days, I showed up before dawn and sat on the wet ground at the edge of the pond. Each time I covered myself in camouflage material so I wouldn’t alert the beavers. During this time I was able to capture some amazing natural behaviors of this beaver family.

There was two adults and three juveniles. It was wonderful to watch the adults going about the business of gathering food for the coming winter. They would swim downstream from the pond to cut branches of willow. Then they would swim back to the den, which was just 50 yards away and around a corner.

Beavers don’t eat wood as many cartoons might portray. They eat green leaves and the soft bark from smaller branches. The left-over woody branches are used in the construction of the dam. So each day I would watch the adults bring back some fresh branches for the family to eat. Later they would carry the bare branches, stripped of their leaves and bark over to the dam.

The adults would also dive down to the bottom of the pond to scoop up mud and rocks and swim to the dam to add on top. They would also add more sticks. This dam was about 4 feet tall, holding back a wall of water. It was wonderful to watch the adults teaching the babies, called kits, to collect construction material for the dam. Each time the adult would dive underwater the kit would dive with the adult. They would both surface together and the kit would swim alongside the adult until they reached the dam, then watch the adult pile the rocks and mud on top of the dam.

Each morning they would work for about 2 to 3 hours allowing me ample time to capture some wonderful images and video before heading to their den to sleep the rest of the day. These were truly busy beavers. Until next time…

Fishing Spider

I’ve been spending a lot of time out on my boat photographing loons, grebes, pelicans and other birds this spring. So, it was fun when I came across something else that was just as photogenic but perhaps not as endearing. It doesn’t have any feathers and has considerably more legs....

Pileated Woodpecker

There are only a handful of birds that elicit pure excitement and joy when it shows up at your backyard feeding station. The Pileated Woodpecker (Dryocopus pileatus) is our largest woodpecker species in American and Canada. Some say it is the second largest woodpecker. It all depends upon if you...

Sage Grouse

I am no stranger to getting up pre-dawn, stumbling around in the dark and finding remote locations, far, far away that I have never been to before. So, it was “just another day at the office” when I recently went to Wyoming and Colorado to visit an old friend, the Greater Sage Grouse...

Hooded Merganser

The spring bird migration is like a high-speed race, or sprint when compared to the fall/autumn migration. Birds returning to the northlands are racing against others of its kind. The first to the best territories and habitat will win the reproductive lottery.

Waterfowl such as Snow Geese...
