Did they forget to fly south?

Native to North America, trumpeter swans live near rivers, lakes, and coastal byways in northern and western US states in the lower 48, as well as in Canada and Alaska. Depending on where they live, these swans are either resident birds or medium-range migrators. What they all require, though, is open water during winter, since their diet consists almost entirely of aquatic plants. That may be why the swans in this image are drawn to the waters of Kelly Warm Springs in Wyoming, which won't freeze even as snow lines the banks.

Trumpeters are the largest living species of waterfowl in North America. The biggest known cob—that's a male swan--weighed almost 40 pounds and had a wingspan of 10 feet. Although in the early 20th century they came perilously close to extinction, today there's an estimated 35,000 trumpeters. Even with the tremendous recovery, it remains illegal to hunt them. And yes, their calls do sound like trumpets, but Miles Davis they aren't. Click below to listen.

It's Slovenia's Independence and Unity Day

Today we're featuring an image of the Slovenian village of Praprotno and its Church of St. Thomas for the country's Independence and Unity Day. On December 26, 1990 the results of a Slovenian vote on the country's independence were announced. More than 95 percent of voters answered 'Yes' to the question: Should the Republic of Slovenia become an independent and sovereign state?

Six months later, on June 25, 1991, Slovenia's Constitutional Charter passed, and Slovenians declared themselves citizens of an independent country. A few days after, a brief conflict between the Yugoslav People's Army and Slovenian Territorial Defense occurred, known as the Ten-Day War, but was brought to a swift end with the signing of the Brioni Agreement on July 7, 1991.

Merry and bright

Germans began decorating Christmas trees with candles as far back as the 1700s, but people wouldn't begin stringing trees with electric lights until the late 1800s. Thomas Edison created the first practical incandescent lights and used them to decorate his Menlo Park Laboratory in 1880. Then three years later, the vice president of Edison's company, Edward H. Johnson, had Christmas tree bulbs especially made for him and he used them to decorate the Christmas tree in his New York City home. But they weren't popularized as a holiday decoration until President Grover Cleveland used them on the White House Christmas tree in 1894. Today, bright scenes like this one in Warsaw, Poland, wouldn't be complete without holiday lights.

If you're celebrating Christmas today, we wish you a merry one.

Seventeen arches at sunset

When it's winter solstice time in the Northern Hemisphere, the setting sun shines under the Seventeen-Arch Bridge of the Summer Palace in Beijing, causing this romantic glow. In the 18th century, during the reign of the Qing dynasty of China, Emperor Qianlong ordered the construction of this 1.1 square mile collection of gardens, lakes, and various structures including temples and small palaces. Today it's one of Beijing's premier attractions and will be crowded today with visitors headed to the bridge in time for sunset.

You've never seen anything like this

This macrophotograph of a snowflake shows the classic, six-sided structure that we've all come to associate with this tiny winter marvel. Until the advent of macro- and micro-photography in the late 1800s, it was impossible to study the structure of snowflakes—they melted too quickly to be accurately sketched under a microscope. Enter Wilson 'Snowflake' Bentley.

A farmer and self-trained scientist from Jericho, Vermont, Bentley was the first person to successfully photograph an individual snowflake. Over his lifetime, he would produce over 5,000 different images, a feat that led him to be the first to observe that every snowflake is unique. He backed up his observation with some math and meteorology as well. He understood that snowflakes form as they fall through the sky, and their growth and appearance are shaped by hundreds of changing conditions, from altitude, temperature, humidity, and more. The combinations multiply exponentially until there are more design possibilities than molecules on earth.

Tree of many colors

Hold the tinsel—the rainbow eucalyptus tree doesn't need decorations to appear festive for the holidays. Its bark displays a palette of bright colors by design. As older layers of bark peel away in strips, new layers packed with green chlorophyll are revealed. These exposed areas eventually transition to hues of blue, purple, and orange as tannins accumulate. The continual peeling allows the tree to shed mosses, lichen, fungi, or parasites along with the bark, while also exposing the chlorophyll underneath, which boosts the tree's ability to photosynthesize. The bark isn't the only unusual thing about this species. While most people associate eucalyptus with koalas and Australia, the rainbow eucalyptus is native to the Philippines and Indonesia. It thrives in tropical climates like Hawaii, where our homepage trees were photographed.

Winter at Valley Forge

Valley Forge, Pennsylvania, is the site of the winter encampment of the Continental Army under General George Washington. On December 19, 1777, about 12,000 soldiers and 400 women and children started to build 1,500 log huts where they would live for the next six months. At the time, the British were occupying the patriot capital of Philadelphia, just a day's march away. Already two and a half years into the war, troops knew the harsh winter would stop the fighting, allowing them to organize and avoid mobilizing for several months. Life, however, was still challenging as they lacked funds for fresh food and clothing. There were no battles at Valley Forge, but nearly 2,000 people died from disease during the encampment.

Washington's leadership was being questioned by some members of the Continental Congress after losing two key battles, and the encampment gave him a chance to regroup. Some have called Valley Forge the birthplace of the American Army, as concepts like basic training started there. In June, the army left Valley Forge, and while the war wasn't won until 1783, many consider the encampment to be a turning point on the way to victory.
