When I first moved out West, I was impressed by the large black-and-white bird I noticed strutting around my yard and campsites, its long black tail dragging on the ground behind it. The bird’s loud “mag-mag-mag” calls slowly became a familiar sound. Now the black-billed magpie has become an important symbol of the West to me, and whenever I see or hear it, I’m reminded how lucky I am to call the Rocky Mountains home.

North America Has Lost 3 Billion Birds, Scientists Say

Sep 19, 2019

Over the past half-century, North America has lost more than a quarter of its entire bird population, or around 3 billion birds.

That's according to a new estimate published in the journal Science by researchers who brought together a variety of information that has been collected on 529 bird species since 1970.

Squirrels eavesdrop on the casual chitchat of birds to figure out when it's safe enough to be out in the open and foraging for food.

Researchers have found that a squirrel becomes incredibly vigilant when it hears the shriek of a red-tailed hawk, but it will relax and resume its food-seeking behavior more quickly if the predator's call is immediately followed by the easygoing tweets of unconcerned birds.

More than 11,000 waterfowl and wetland birds were killed by hail Sunday at the Big Lake Wildlife Management Area west of Billings.

Loon Calls: From Inquisitive To Bone-Chilling

Jul 29, 2019
When a boat steers too close to a nest, the owner loon will snap its bill open and closed, transforming air into wavy notes that writer John McPhee described: “If he were human, it would be the laugh of the deeply insane.”

Loon calls flow through our veins, seep into our bones and sinew. For a moment, we become the wild flute music that curls into every recess of the lake. The echo pulses within us long after the stillness returns.

Loons call in four ways, each carrying a meaning that, at some level, humans have come to understand.

Viktoriia Radchuk, an evolutionary ecologist at Berlin's Leibniz Institute for Zoo and Wildlife Research, wanted to know how animals were responding to climate change.

So she scoured the results of more than 10,000 animal studies — on species from frogs to snakes, from insects to birds to mammals — looking for information on how changing environments were affecting animal behavior. Based on the available data, she decided to focus on birds in the Northern Hemisphere.

Birds Of A Feather Flock Together ... To Bathe In Ants?

Anting is a bizarre form of bird behavior that has often been observed but is not well understood. It typically involves a bird picking up ants and rubbing or jabbing them into the feathers, especially under the wings and tail. The action is so rapid and vigorous that the bird will often knock itself over onto the ground.

As a bird biologist who studies bird songs, I immediately recognize most sounds I come across in nature: the winnowing of a Wilson’s Snipe, the smack of a Dark-eyed Junco, the zee-chubbity-chub of a Rufous Hummingbird, just to name a few. For me it is a matrix of sound, as diverse and varied as the surrounding landscape. When I hear a strange sound in nature, I can’t give up until I determine its source.

It’s spring in the Rocky Mountains, the air is filled with birdsong and my feathered neighbors are back again. Recently, a pair of American robins arrived and set up housekeeping in the neighbor’s maple tree, just as a pair did last year. There’s a song sparrow in residence again in the lilacs near the creek, belting out its bubbling song. Riding my bike to work takes me past a small field, and sure enough, there’s a western meadowlark back again singing from the same telephone pole and claiming that field for his own.

I’m not sure if I’ve ever been on a river, at any time of year, and not seen a Great Blue Heron. They seem to stand as solitary sentries on the rivers of Montana, but also on rivers from Canada to South America.
