CRITTERS OF NORTH IDAHO: Common Loon
Christian Ryan Correspondent | Hagadone News Network | UPDATED 5 years, 10 months AGO
When we think about “waterfowl,” ducks, geese and swans are usually the birds that come to mind. However, there is another Idaho bird that spends much of its time in the water. In fact, it spends so much time there it can barely get around on land. I am talking about the common loon, otherwise known as the great American diver (Gavia immer).
The common loon is a medium-sized bird, about 3 feet long, weighing up to 12 pounds, and they have a wingspan of 4 to almost 5 feet. They have a black head, neck and body, with a white “necklace” and distinctive white-spotted markings on its back and wings. If you ever find yourself in a staring contest with a loon, you’ll see it looking back at you with its large red eyes.
Common loons get their name from the awkward way they move about on land. Unlike ducks, their legs are situated at the rear of their bodies and they can’t be swiveled downward. This forces loons to adopt a clumsy-looking lumbering gait as they “walk.” Thankfully, the birds don’t need to be on land much; they are capable of flying away from land predators, and they’re much more at home in the water — so long as a body of water has low turbidity, plenty of food and is large enough for them to take off.
Common loons are not terribly picky about where they live. They are found in lakes and ponds all across the United States and Canada. Because the birds are migratory, they don’t live across this entire range all year long. They tend to breed in the northern United States and Canada, and they spend the winter along the Atlantic and Pacific coasts.
What they lack in their ability to move around on land, they more than make up for it in their ability to swim powerfully in the water while pursuing prey. Their legs are muscular and their feet are webbed, making it easy for them to plow through the water after the minnows, rock cod, kill fish, suckers and perch — basically any fish under 10 inches long — they want to eat. They won’t turn their beaks up for frogs, mollusks, aquatic insects or leeches either, and will even nibble on algae and pondweed from time to time. Amazingly, common loons can swallow small prey while underwater.
Predators are never far away when you’re a loon, and they come in all shapes and sizes. On land, they’ve got to watch out for raccoons, weasels and even skunks. Gulls, ravens and crows attack from above. Loons even have to be ready to zip away from predators in the water, like pike fish.
Loons are known for making wailing, tremolos and even yodeling-like calls that can be heard from a long way off. The calls are unique to individual birds, so ornithologists (scientists who study birds) can use them to tell whether their favorite loons happen to be in the area. As they migrate inland to their breeding grounds this spring, try to find them by listening for their calls!

If you see this bird swimming across the water’s surface from a distance, chances are you will mistake it for a duck.
Critters of North Idaho: Northern pike
When we talk about human disturbance of the environment, we usually think of the overharvesting of trees, overhunting and littering. But we can also disrupt the natural balance by introducing species of animals and plants into non-native habitats. This is what happened in the case of the northern pike.
Critters of North Idaho: Ye ol' vole
If you see a little rodent scurrying about in the thicket or under the snow, you may think it’s a mouse. And it may be a mouse, but at first glance it is very difficult to tell a mouse apart from another little rodent, the vole. So difficult, in fact, that voles are often mistakenly referred to as “field mice.” What makes these little scurriers so different from each other? For starters, they belong to different families.
