Red-necked grebes during breeding season
Red-necked grebes during breeding season
The red-necked grebe has a bit of a split personality—in fact, it only lives up to its name about half the year. Its feathers are not red but brambly brown and gray throughout the winter, when it lives a low-key, quiet life in salt water along North American and European coasts. But just before it migrates to a northerly lake, pond, or swamp for breeding season, the plumage around the grebe"s throat turns a distinctive rust-red. Both males and females undergo the plumage change.Desktop Version
Happy birthday, Capitol Reef National Park
Happy birthday, Capitol Reef National Park
You won"t find a lot of solitude on the Hickman Bridge Trail, a 1.7-mile route in Capitol Reef National Park that leads to this magnificent natural arch. The trail is used by hikers, runners, and nature lovers drawn by incredible rock formations, gullies, and remnants from the ancient Fremont Culture civilization. Hickman Bridge itself is one of the best-known geologic features of the park.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
Noctilucent clouds
Noctilucent clouds
It"s around this time of year when some lucky people get to witness these rare, wondrous clouds. Known as noctilucent, or "night-shining," clouds, they"re the highest clouds in our sky and are only visible during summer. They"re made up of icy dust glowing at the edge of space, roughly 50 miles above the planet"s surface. The trick to seeing them is to gaze up into the sky at twilight, when sunlight is not reaching the Earth"s surface, but is still shining through the high-altitude noctilucent clouds. These clouds occur more often at high latitudes but have been seen lower than 50° north and south.Desktop Version
Milford Sound/Piopiotahi rainforest in New Zealand
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
International Tiger Day
International Tiger Day
Famously solitary, tigers seldom live in groups unless they"re still cubs staying close to their mother. This rare "streak," as a group of tigers is called, is an exception. So much so, they became the subjects of a TV documentary called "Girl Gang of Telia." Today, on International Tiger Day, we"re featuring these tigress sisters from the Tadoba Andhari Tiger Reserve in central India, a protected area that includes Tadoba National Park.Desktop Version
Longs Peak, Rocky Mountain National Park
Longs Peak, Rocky Mountain National Park
One of the 53 "fourteeners" in Colorado—mountains that exceed 14,000 feet—Longs Peak still manages to reach higher into the heavens than any other mountain in Rocky Mountain National Park at 14,259 feet. Thousands of climbers set off every year to attempt the summit. Some climbers will try to reach the peak of every fourteener in the US during their lifetimes—that"s 96 different mountains.Desktop Version
Mada in Saleh, Saudi Arabia
Mada in Saleh, Saudi Arabia
About 2,000 years ago, Mada"in Saleh, or Hegra as the Romans called it, was a thriving city of the Nabataean Kingdom, and a center for the trade of spices, incense, and myrrh, a valuable tree resin used to make perfume and medicine. The Nabataeans were Arab people whose precise origins are unknown. They lived in northern Arabia and the Southern Levant. Mada"in Saleh was their second-largest and southernmost city after Petra, their capital city to the north. About halfway between Petra and Mecca, Mada"in Saleh served primarily as a trading crossroads and was instrumental in establishing the Nabataeans as prosperous middlemen to the rest of the ancient world.Desktop Version
Mangrove Conservation Day
Mangrove Conservation Day
Although we think of forests as trees on land, some of the most important trees grow in water, or more precisely, marshland. Mangrove forests, like this one in Saloum Delta National Park in Senegal, are vital components of the world"s coastal ecosystems. Mangroves survive where no other trees can, in salty, low-oxygen coastal waters exposed to tides and storms. They grow up to 30 feet high primarily in tropical and subtropical regions and are able to store vast amounts of carbon, making them crucial to moderating our climate. Mangroves also act as nurseries for fish and aquatic life. And with their complex, interwoven root systems, they protect coastlines from erosion. Today we join the UN in shining a light on the necessity and fragility of mangroves: July 26 is the International Day for the Conservation of the Mangrove Ecosystem.Desktop Version
National Merry-Go-Round Day
National Merry-Go-Round Day
Today we"re celebrating a necessary staple of fairs, carnivals, and boardwalks: the merry-go-round. You may know it as a carousel, like the Golden Gallopers Carousel at the seaside in Brighton, England, seen in today"s photo. The word "carousel" is possibly derived from the Spanish "carosella," meaning "little war." Carousels have a history that goes back centuries, with roots in medieval jousting competitions. As the war game grew in popularity, commoners without horses wanted to participate, and carousels with wooden horses soon appeared at fairgrounds. The popularity of carousels led to many advancements over the years, including the up and down galloping menagerie of animals real and imagined, and the instantly recognizable music that became widespread after 1803.Desktop Version
Amelia Earhart
Amelia Earhart
Few people in modern history have captured our imagination as much as the famed aviator Amelia Earhart, born on this day in 1897. She was doubly a pioneer of her day, a skilled pilot when flying was a relatively new and daring endeavor, and a woman in a field dominated by men. Earhart"s legend was made, sadly, not as much by her piloting accomplishments as by her sudden disappearance in 1937 when her fame was still ascending. The 39-year-old famously went missing, along with navigator Fred Noonan, in the middle of the Pacific Ocean, near Howland Island, while attempting to fly around the world. The official search for Earhart and Noonan lasted 17 days. The US Navy and Coast Guard searched 150,000 square miles of the Pacific, an effort that became the most expensive search in history at the time. Her husband, George Putnam, led a private search in the months that followed. No verified trace of Earhart, Noonan, or the twin-propeller Lockheed Electra plane has ever been found.Desktop Version
National Moth Week
National Moth Week
How come bees and butterflies get all the pollinator credit? Moths may not be as buzzy or flashy, but they get the job done, too. Cue National Moth Week, which starts today. Whether you generally swat at moths with a rolled-up newspaper or drape them in a towel to release outside, there"s a place for you in Moth Week. You can join enthusiastic "moth-ers" around the world to observe and document our flying friends and to help us understand more about them.Desktop Version
Our Lady of the Rocks
Our Lady of the Rocks
Local legend here in Perast, Montenegro, has it that two brothers were returning from a dangerous sea voyage in 1452 when they spotted an icon of the Virgin Mary and Child in the waters near Saint George, a natural island in the Bay of Kotor. One of the brothers had injured his leg on the journey, but in the morning it had healed. Taking this as an omen, they vowed to honor the Virgin Mary by building her a church on the spot where they"d found the icon. They began dropping stones there, and even scuttling old ships. A tradition was born, and over decades, the fishermen of Perast would drop a stone in the water at that spot before heading to sea.Desktop Version
Abbey Gardens in Bury St Edmunds, England
Abbey Gardens in Bury St Edmunds, England
Abbey Gardens in Bury St Edmunds comprise a living, vibrant park, and just not because of their 14 acres of colorful displays and ornate flowerbeds. The gardens have changed with the times, all while still jealously guarding their history. The site here in the county of Suffolk, in eastern England, was originally home to a powerful Benedictine abbey in medieval times—in fact, 2022 marks the 1,000th anniversary of the storied abbey. You can still visit the abbey ruins and marvel at the 14th-century Great Gate and Norman Tower, which have survived through the ages. Nathaniel Hodson took the original abbey gardens and designed them as a botanical garden in 1831, using the Royal Botanic Gardens in Brussels, with their concentric circles, as his inspiration.Desktop Version
National Moon Day
National Moon Day
Bigger and brighter than anything else you can see from Earth in the night sky, the moon has inspired our calendar, our songs, our art, our stories, and our dreams. Today, on National Moon Day, we remember one dream that came true on this date in 1969: the day humans first set foot on the lunar surface. So far, it"s the only place beyond our planet that humans have visited.Desktop Version
National Bison Month
National Bison Month
July is National Bison Month and we"ve chosen today to honor America"s official and largest land-dwelling mammal. The male American bison in today"s photo is lazing among wildflowers in Yellowstone National Park, the only place in the country where there"s been a continuous population of bison since prehistoric times. Once widespread across the American plains and revered by Native Americans, they numbered in the tens of millions. Tragically, settlers hunted the bison nearly to extinction by the late 1800s. Fewer than 1,000 of the giants were left in 1905 when the American Bison Society was formed to save them. These days, the population has stabilized with a little more than half a million bison spread across the country, with a few thousand living freely on the plains at Yellowstone.Desktop Version
Marine Day in Japan
Marine Day in Japan
The striking coastline of Omijima Island has earned it the nickname the Alps of the Sea. Its sheer cliffs and dramatic angles certainly echo the skyscraping peaks in that European mountain range. But a visit to Omijima Island will take you to the other side of the world, to Kita-Nagato Kaigan Quasi-National Park, in Yamaguchi Prefecture, Japan. Year-round scuba diving adventures reveal a world under the waves just as beautiful as the one above the surface.Desktop Version
The Wave at Coyote Buttes
The Wave at Coyote Buttes
By showing you this coveted sight, we"re saving you a bit of an ordeal. To get a close-up view of the Wave, a whorled sandstone formation in the northern Arizona wilderness, you"d have to navigate a rugged and mostly trail-free hiking route in typically scorching temperatures. You"d also need to have a permit in your pocket. To protect the landscape, only a small number of permits are available, offered through a daily lottery. But maybe for you the journey is at least as important as the destination? If so, this is just one hike of many in the expansive Paria Canyon-Vermilion Cliffs National Monument, which protects more than 100,000 acres of Arizona and Utah canyonland.Desktop Version
American goldfinch
American goldfinch
Birds, bees, and flowers grace today"s photo, but we"re going to bet that potato chips will be what you remember tomorrow. First the basics: We"re in South Carolina looking at a beautiful American goldfinch perched atop a sunflower. While the matching color scheme makes for a great photo, it"s likely this little bird has stopped for a meal. American goldfinches are among the strictest vegetarians in the bird world, preferring grains and seeds, especially sunflower seeds. That"s why it"s not uncommon to see them in neighborhoods with well-stocked bird feeders. In fact, human activity has generally benefited American goldfinches overall. The birds thrive in areas where forests have been removed—they prefer open meadows or fields covered in weeds.Desktop Version
Arrone in Umbria, Italy
Arrone in Umbria, Italy
Close your eyes and picture a charming medieval Italian village, perched on a hill, church bells marking the hours, a hazy spread of patchwork fields fading into the distance. Well, that"s the ancient village of Arrone. (On second thought, we probably didn"t need the photo.) Arrone looks over the Valnerina, a valley carved by the River Nera, which twists its way through Italy"s scenic Umbria region, known as the Green Heart of Italy.Desktop Version
Shark Awareness Day
Shark Awareness Day
For Shark Awareness Day, let"s consider things from the shark"s point of view. Sharks get a bad rap. They may be apex predators of the oceans, but we"re the ones most responsible for reducing their populations by more than 70% in the past half-century. Rather than perpetuate the stereotype of sharks being dangerous, let"s think of them as they are—amazing sea creatures with hundreds of millions of years of history in their genes. We may not always want to encounter them face to face, but they deserve our respect and for the health of our oceans as whole, sharks deserve protection.Desktop Version
International Rock Day
International Rock Day
Today is International Rock Day and we"re giving due respect to these geologic wonders. It might seem odd to sing the praises of rock, but think about it. Rocks have been with humankind since the beginning. From tools to housing to weapons, they"ve been key to our survival. A period of our history was so reliant on rocks that it will be forever known as the Stone Age. We would not be where we are today without the many minerals found on our planet, so rock on!Desktop Version
Bay Marker Lookout, Sydney Olympic Park, Australia
Bay Marker Lookout, Sydney Olympic Park, Australia
It"s an easy, circular trail to the Bay Marker Lookout, but you have to make it under your own steam—sorry, no cars allowed. This is one of the five Sydney Olympic Park Markers, cone-shaped earth mounds installed for the 2000 Olympics in Australia. They are cleverly placed to look from the air like the Australian flag"s Southern Cross. From the ground, the Bay Marker gives a stunning full-360-degree view of Wentworth Common—a large grassy park—and the larger Olympic Park and stadium. You can also look over Homebush Bay (the community and the body of water) to the north. It"s a dramatic melding of urban landscape, the city skyline, the wetlands and greenery, rivers, and beaches.Desktop Version
World Population Day
World Population Day
The bustling city streets of Barcelona seem as good a place as any to mark World Population Day. More and more of us are heading to the city. It"s estimated that 2007 was the first year in which more people lived in cities than in rural areas. If current trends continue, by 2050 about two-thirds of the world population will be living in cities. City planners and government officials will need to account for this rapid increase as power grids, water supplies, public transit, and emergency services will all be stretched.Desktop Version
Ölüdeniz, Turkey
Ölüdeniz, Turkey
Whether you love snorkeling, scuba diving, swimming, paragliding, or simply soaking up some sun, Ölüdeniz on Turkey"s Turquoise Coast will fit the bill. The name of the village and beach—Ölüdeniz—literally means "Dead Sea," a reference to the calm water, but it"s better known as Turkey"s Blue Lagoon for the stretch of tranquil waters set off from the ocean by a long sandbar. Much of the area is protected inside a national park, and the Ölüdeniz beach proudly holds the Blue Flag certification by the Foundation for Environmental Education, which recognizes high environmental and quality standards.Desktop Version
