Great horned owl fledglings
Great horned owl fledglings
These little furballs will grow up to be great horned owls, fierce predators with camouflage coloring. For now, they sport a layer of fluffy light-colored down and have yet to grow their full "horns"—tufts of feathers known as plumicorns. But they will become voracious carnivores capable of hunting down prey larger than themselves, including other owls. Typical meals will consist of small animals like rabbits, squirrels, mice, and even scorpions.Desktop Version

International Womens Day
On International Women"s Day, we"re at Madrid"s iconic Cibeles Fountain and City Hall, which have been lit up in purple—one of the day"s official colors, representing justice and dignity. Each year, marchers pass by the Great Mother of the Gods on her chariot drawn by lions, as they turn out in their thousands to campaign for gender equality in Spain"s capital city.Desktop Version
Daylight saving time
Daylight saving time
Just like the European hare, we get a little more hop in our steps this time of year—and a bit more daylight as well. It"s the second Sunday of March, when most Americans and Canadians "spring forward," setting their clocks ahead one hour in observance of daylight saving time (DST). Then on the first Sunday of November, we"ll "fall back" by turning our clocks back an hour.Desktop Version
World Rainforest Day
World Rainforest Day
Welcome to the largest tropical rainforest on Earth. Our homepage image was taken in Peru, home to about 13% of the Amazon rainforest. Most of it, about 60%, is in Brazil, while 10% is in Colombia. Bolivia, Ecuador, French Guiana, Guyana, Suriname, and Venezuela also have sections within their borders. Covering nearly 40% of South America, the rainforest is teeming with life, including endangered species like jaguars and giant otters, more than 40,000 plants, and thousands of birds and butterflies. Millions of people also live in the Amazon.Desktop Version

Hawai i Volcanoes National Park at 106
The orange glow of a lava tube like the one pictured here is a frequent sight on Kīlauea, the youngest volcano on the island of Hawaii. In near constant eruption for the last 40 years, Kīlauea is widely considered the most active volcano in the world and is the main attraction at Hawai"i Volcanoes National Park, which was created on this day in 1916. The park, which was designated an International Biosphere Reserve and a World Heritage Site, also includes another active volcano, Mauna Loa, the world"s most massive shield volcano, which last erupted in 1984. Together, they are among the most studied volcanoes in the world.Desktop Version
International Women s Day
International Women s Day
This famous feisty girl stands her ground in front of the New York Stock Exchange in lower Manhattan, a striking reminder as we celebrate International Women"s Day that we still have work to do in the quest for gender equality. Kristen Visbal"s bronze sculpture "Fearless Girl" took up her power pose in 2017 facing down the iconic Wall Street bronze statue called "Charging Bull." For the 2021 observance of International Women"s Day, the corporate sponsor of "Fearless Girl" added broken glass around her, with a plaque that read: "Today"s broken glass ceilings are tomorrow"s stepping stones."Desktop Version
World Rainforest Day
World Rainforest Day
Perhaps no other place on Earth plays a more crucial role in sustaining life as we know it than the Amazon rainforest, the largest in the world. The Amazon spans nine countries in South America including Ecuador, where this pristine ecoregion is protected by the Yasuní National Park, shown here. Today is set aside as World Rainforest Day, to remember the vital role of this and other rainforests and to champion efforts to protect them. The world"s rainforests are under threat like never before from deforestation driven by agriculture and cattle ranching. Some studies indicate that humans have degraded or destroyed more than half of the world"s rainforests. Fewer trees means warmer temperatures, which increases the risk of drought and wildfire and compounds the damage of deforestation.Desktop Version
Leap day
Leap day
Are you a "leapling"? No, not like this Eurasian red squirrel; rather, that"s the term for anyone born on leap day. A leap year is a calendar oddity that exists because Earth"s orbit and our usual year count are slightly out of sync. Earth takes 365.25 days to revolve around the sun. To compensate for those extra 5 hours, February gets an extra day—leap day—every four years. The concept, dating back to the ancient Romans, was refined in the Gregorian calendar, introduced in 1582 by Pope Gregory XIII. While the purpose of the day is to keep our year aligned with the solar calendar, it can also serve as an extra day to prepare for spring! Cultures worldwide mark leap days and years with unique customs. In Ireland and Britain, women propose to men, in Greece, marrying during a leap year is said to bring misfortune, and in France, a satirical newspaper is published.Desktop Version
75th anniversary of the Spruce Goose
75th anniversary of the Spruce Goose
Today we"re looking back to a time when an eccentric billionaire"s dream of reaching new heights was still a novel idea. It was 75 years ago today that Howard Hughes" "flying boat," dubbed the "Spruce Goose," made its one and only flight. Officially named the Hughes H-4 Hercules, the press persisted in calling it the "Spruce Goose" even though it was constructed almost entirely of birch wood. The plane was commissioned in 1942 by American industrialist Henry Kaiser, who supplied ships to the US during World War II. Kaiser recruited Hughes—the film producer turned pilot, engineer, and business magnate—to build a flying cargo ship that could avoid German submarines while transporting troops and war supplies across the Atlantic. The contract called for three of the planes to be built within two years. Hughes was still working on the design when the war ended—in the end, he delivered only the one in our photo, two years after V-E Day.Desktop Version
Quiver trees in Namibia
Quiver trees in Namibia
The quiver trees pictured on our homepage are uniquely suited to Namibia"s hot, dry climate. They are not trees at all, but an endangered species of aloe plant. These succulents can grow up to 30 feet tall and live for 200 years. The name comes from the Indigenous San people who made quivers out of the plant"s tube-shaped branches to hold their arrows while hunting. You can see scattered quiver trees across southern Namibia, but for sheer numbers, head to the Quiver Tree Forest, where more than 200 of these distinctive plants grow among dolerite rock formations outside the city of Keetmanshoop. In June and July, during Namibia"s winter, you can see the plant"s flowers in bright, yellow bloom.Desktop Version

Milford Sound/Piopiotahi rainforest in New Zealand
Today we"re taking a tramping trip to New Zealand"s South Island to visit the place Rudyard Kipling once called the eighth wonder of the world, Milford Sound and its surrounding rainforest. Tramping, New Zealand-speak for hiking, is incredibly popular at Milford Sound. Nearly a million tourists visit the fjord every year, despite its somewhat remote location. Originally overlooked by European explorers, the area is now known for its beauty and abundance of wildlife. It"s not uncommon for visitors to spot dolphins, humpback whales, and native Fiordland penguins.Desktop Version

Pumpkin field, Victoria, British Columbia, Canada
As fall covers the landscape with amber hues and the chill of Halloween approaches, it"s time to start carving some spooky jack-o"-lanterns. Originally from Ireland and Scotland, this craft was brought to America by immigrants who initially made lanterns from turnips and potatoes but later found pumpkins more plentiful and easier to carve. Once hollowed out and lit with candles, the gourds were transformed into flickering defenses against evil spirits.Desktop Version
Apple Tree Day
Apple Tree Day
Apple Tree Day is a nationwide ode to the art of apple cultivation and the health benefits this beloved fruit brings to our lives. Apples made their way to North America with European colonists in the 17th century. In 1625, the first apple orchard in North America was planted in Boston by William Blaxton. Today, from Red Delicious to Honeycrisp to Pink Lady, some 200 varieties are grown in the US. The chaffinch on our homepage today is pictured amid tiny crab apples. Sure, they can be a bit tart, but they make for a lovely display in winter and some birds depend on them when other food is scarce. Sliced, baked, in a salad, or as cider, how do you like them apples?Desktop Version
Halemaumau Crater, Hawaii Volcanoes National Park
Halemaumau Crater, Hawaii Volcanoes National Park
As National Park Week wraps up today, let"s explore a park in a land sculpted by fire and time—Hawai"i Volcanoes National Park on the Big Island. The Halema"uma"u Crater is an intermittent lava lake in Kīlauea, one of Earth"s most active volcanoes. Since it was first documented in 1823, volcanic activity has caused the crater to fill with lava, partially collapse, erupt in fountains of lava, expand to twice its size on two occasions, and at times fill with groundwater. All this activity demonstrates the unpredictable raw power that lies below the surface of the Earth. The natural and cultural importance of this site led to the establishment of Hawai"i Volcanoes National Park in 1916, and to it being named a UNESCO International Biosphere Reserve and World Heritage Site in the 1980s.Desktop Version
International Day of Mangrove Conservation
International Day of Mangrove Conservation
Natural vegetation is sparse in the United Arab Emirates, due to its hot and dry desert climate. But along its coast, mangroves have taken root. These hardy trees and shrubs are halophytes, salt-tolerant plants that can filter 90% of the salt from the seawater they live in. Despite their resilience, mangroves are threatened globally, largely due to human activity. Mangrove coverage is thought to have halved over the past 40 years, and they are dwindling much faster than forests overall. The UN has established the International Day of Mangrove Conservation, scientific funding, Global Geoparks, and World Heritage sites to try to reverse these trends. These efforts are vital; mangroves help prevent erosion and protect against storm surges, as well as providing a home for fish, crustaceans, and other wildlife.Desktop Version
Chestnut-eared aracari in the Pantanal, Brazil
Chestnut-eared aracari in the Pantanal, Brazil
Today we"re following our nose to the Pantanal in Brazil to visit this member of the toucan family named for the brownish plumage around its ears. What, you"ve never heard of a chestnut-eared aracari? That could be because aracaris don"t really stand out among toucans at a glance: They have long, colorful bills, and they mate for life, always laying eggs in the same nest year after year. But aracaris are much more social nesters: Up to six aracari adults and all their babies might live in one nest.Desktop Version
Bearded reedlings in Flevoland
Bearded reedlings in Flevoland
Flevoland, the 12th and newest province in the Netherlands, has only been around since 1986. Not only was it not established until this late date, but before the mid-20th century, much of the land here simply didn"t exist. Flevoland was created through vast land reclamation projects in the 1950s and "60s. While the Dutch had been reforming their landscape to meet their changing needs for hundreds of years, the 20th century would see their most dramatic and ambitious projects realized. The province"s anthem is the fitting "Waar Wij Steden Doen Verrijzen" ("Where We Let Cities Arise"). It"s an ode to pushing back the sea and creating a "province that"s not bad, youngest part of the Netherlands. Where it is nice to live, my beloved Flevoland!"Desktop Version
Mount Rainier National Park
Mount Rainier National Park
In the shadow of Mount Rainier, a carpet of wildflowers bursts into life. Every summer, the meadows around this mountain are colored with vivid shades of blooming subalpine flowers: purple asters, pink coralroot, and yellow tiger lilies, and more. Also known as Tahoma, at over 14,400 feet, Mount Rainier is the tallest mountain in the state of Washington. It is covered by 36 square miles of glaciers and permanent snowfields, the highest glacier ice cover of any mountain in the lower 48 states.Desktop Version
Arc de Triomphe du Carrousel and the Louvre Pyramid
Arc de Triomphe du Carrousel and the Louvre Pyramid
Paris features an impressive stretch of parks, gardens, and monuments called the Axe historique, or historical axis, that starts at the Louvre Museum, in the city center, and extends west, ending at La Grande Arche. Today"s image shows the Arc de Triomphe du Carrousel at the eastern end of the route, with the embodiment of Peace riding a chariot atop it. It shouldn"t be confused with the better-known and much larger Arc de Triomphe de l"Étoile, which stands 2 miles away, halfway along the Axe historique. It"s a lovely walk from one to the other, through the Jardin Des Tuileries and along the famous Avenue des Champs-Élysées. If the statue on the left side of the photo caught your eye, wave hello to King Louis XIV on horseback.Desktop Version

"There is no friend as loyal as a book," Ernest Hemingway once wrote. On World Book Day, we are honoring these loyal friends in the German city of Stuttgart, where a huge monolithic cube is both a modern landmark and home to the city library. Opened in 2011, this striking building was designed by architect Eun Young Yi to be a calming, meditative space in a bustling city. Its interior is white, with splashes of color provided by the books that line its walls.Desktop Version

Today we"re heading to the Netherlands to visit the red foxes at the Amsterdamse Waterleidingduinen Nature Reserve. This protected area about 8 miles west of Amsterdam is host to not only a diverse assortment of plants and animals, but also hundreds of specially designed sand dunes that help filter rainwater. The Waterleidingduinen ("water supply dunes") have been the source of the city"s drinking water since the 19th century.Desktop Version

Molokini Crater, Maui, Hawaii
Today we"re at Molokini Crater. This pleasant crescent in the Pacific Ocean lies in the "Alalākeiki Channel between the Hawaiian islands of Maui and Kaho"olawe. The islet is all that remains of a volcano that erupted about 230,000 years ago. According to Hawaiian mythology, Pele the fire goddess was in love with a man named Mo"o. The trouble was that Mo"o was in love with another woman. Pele"s revenge was typically violent: She cut her rival in two, her body becoming Molokini, while her head became Pu"u Olai, a cinder cone on Maui.Desktop Version
National Trails Day
National Trails Day
Today is a great day to take a hike! Each year, National Trails Day brings together nature lovers, government agencies, and businesses to preserve hiking trails for everyone to enjoy. Looking for a stunning spot to stretch your legs? We suggest South Kaibab Trail in the Grand Canyon, seen here. The trail starts with a series of switchbacks known as "The Chimney," which leads to a steep, narrow descent—prepare for an invigorating workout! All that hard work will pay off though—fresh air and exertion can boost your mood, improve sleep, and reduce the risk of heart disease. Not to mention the panoramic views you can enjoy from the trail"s scenic viewpoints.Desktop Version
Grand Canyon National Park turns 105
Grand Canyon National Park turns 105
Happy birthday to Grand Canyon National Park! It"s been 105 years since this Arizona landmark was designated a national park by President Woodrow Wilson in 1919. The origins of this exceptional landscape, carved by the Colorado River, wind, and landslides, date back up to 6 million years. Alongside its steep valleys and colorful rock formations, the canyon holds the stories of Native Americans, European, and American pioneers—the oldest human artifacts found here date back nearly 12,000 years. In addition to tourist adventures such as cruising on the Colorado River, joining the Trail of Time walking tour, or climbing up to the Desert View Watchtower, the park is also a UNESCO World Heritage Site and a registered International Dark Sky Park for crystal-clear stargazing.Desktop Version
