Relationship status: It s complicated
By posing for us, are these red-billed oxpeckers imposing on the impala? Well, science hasn"t quite decided on this one. The relationship between parasite-eating birds and hoofed mammals was once considered a textbook example of mutualism, with oxpeckers cleaning up the ticks and fleas that bug the bigger beasts. Which is what we"d like to think is going on here.Desktop Version
Prayer flags in Phobjikha Valley, Bhutan
Prayer flags in Phobjikha Valley, Bhutan
This kaleidoscopic column is made up of prayer flags, blowing in the breeze in the Phobjikha Valley, Bhutan. Prayer flags come in five repeating colors representing different elements in nature, blue for the sky, white for air, red for fire, green for water, and yellow for earth. The fluttering fabrics, inscribed with spiritual scripts, are usually raised during times of prosperity, such as on Bhutan"s Nyinlong, their traditional day of solstice, which takes place today. As the flags fade over time, adherents believe this signifies that the prayers have been heard and are being carried away by the wind, infusing the surrounding area with positivity and spirituality.Desktop Version
Whale hello there!
Whale hello there!
It"s whale-watching season here off the coast of Massachusetts and these humpback whales and their seagull friends are in a feeding frenzy. Here"s a little tip if you ever find yourself seeking out humpbacks: Look for birds. Where there are swarms of dive-bombing birds, there will be fish, and where there are fish, there may be humpback whales.Desktop Version
Put your helmet on, we’re going for a hike
Put your helmet on, we’re going for a hike
You’ll need to wear a safety helmet before stepping onto the cliff-hanging path that passes above the Gorge of Gaitanes in Spain"s Málaga province. Look around, but don’t forget to look down from the glass-floor observation platform. This is your opportunity to fully appreciate the 325-foot drop below and consider what life must be like as a mountain goat. The renovated path is far less dangerous than the original, which for many years had no guard rails. Made for workers back in 1905, the first walkway provided access between El Chorro and Gaitanejo hydroelectric power plants. After King Alfonso XIII visited in 1921, the walkway was given its nickname, El Caminito del Rey (The King’s Little Pathway). But after years of use and lack of upkeep, the nickname was updated to ‘The world’s most dangerous walkway.’Desktop Version
Zion National Park turns 103
Zion National Park turns 103
Our photo brings us to a 16-mile stretch of the Virgin River where it cuts a spectacular thousand-foot-deep gorge through the upper reaches of Utah"s Zion Canyon. Flowing through Zion National Park (which turns 103 today!), the Virgin River is home to unique plants and animals that aren"t found anywhere else, due to the unique intersection of biomes found where the Colorado Plateau, Great Basin, and Mojave Desert all meet. Without the water of the Virgin River system, creatures like the woundfin minnow, one of rarest species on the planet, couldn"t exist.Desktop Version
Rice processing in Bangladesh
Rice processing in Bangladesh
In Bangladesh, a nation that"s never recorded a freezing temperature, rice growing is a year-round affair. But growing an aquatic crop in the dry season—October through March—is complicated, requiring high-yield plant strains and additional irrigation.Desktop Version
Blink and you ll miss it
Blink and you ll miss it
The mountain hare is doubly hard to catch sight of, because along with its tremendous speed, it"s terrifically well camouflaged. These two traits help the iconic species survive in the rugged mountains and uplands of northern Europe and Asia—this hare is dashing across a heath in the Scottish Highlands. When they have to, these speedy leporids can dart away as fast as 50 mph, at least for short distances, allowing them to outrun predators and disappear safely into the heather. But a would-be predator may not even spy them to begin with—mountain hares change coats, or molt, several times a year, their fur going from brown and gray in summer, to white-gray in winter, helping them to blend into their surroundings whatever the season.Desktop Version
Poinsettia Day
Poinsettia Day
During the holiday season, poinsettias brighten up homes in suitably festive coloring, serving as symbols of goodwill. December 12 marks National Poinsettia Day, a special occasion to celebrate this holiday favorite. The plant was introduced to the US by Joel Roberts Poinsett, a botanist and former minister to Mexico who died on this day in 1851. Poinsettias can be found growing in the wild from Mexico to Guatemala. The ancestors of the modern, commercially available version have been traced to the Mexican state of Guerrero. The crimson-leaved plant was used by the Aztecs as a red dye and as a fever-reducing medicine.Desktop Version
Llama Day
Llama Day
Prick up your ears and crane your neck—it"s National Llama Day. Part of a family that includes camels, alpacas, and guanacos, llamas have long been domesticated in South America because of their hardiness and ability to thrive on the bleak vegetation in the mountains and plateaus of the Andes. At up to 6 feet tall and weighing up to 400 pounds, they were used primarily as pack animals for about 6,500 years. They were also bred as a source of food, hides, tallow for candles, dung for fuel, and fabric. While inferior to alpaca and guanaco wool, llama fleece is soft, warm, durable, and fairly lightweight. It"s used for clothing, rugs, and rope.Desktop Version
Capitol Reef National Park, Utah
Capitol Reef National Park, Utah
Behold the rugged grandeur of Utah"s red rock country. This hidden gem of the American Southwest is Capitol Reef National Park, a tapestry of towering cliffs, twisting canyons, colorful sandstone buttes, and sweeping desert landscapes. Less popular than Zion and Bryce Canyon, the park offers a pleasantly uncrowded experience for visitors keen to enjoy this spectacular landscape. It is also home to a wide variety of plants and animals, including the elusive desert bighorn sheep and more than 230 bird species. But its crown jewel is the nearly 100-mile long Waterpocket Fold, a 7,000-foot-high step in the rock layers, officially known as a monocline. This massive wrinkle on the surface of the planet was formed around 50 to 70 million years ago.Desktop Version
Last stop before leaving the solar system
Last stop before leaving the solar system
Official telescopic confirmation of Neptune"s presence in our solar system came on September 23, 1846, and it was a big deal partly because Neptune is the only planet in our solar system not visible with the naked eye. Credit for this discovery inspired a dust-up in the international astronomy community, as scientists from both Britain and France claimed they had been the first to predict the existence and position of the eighth and most-distant planet in our solar system before it was seen through a telescope. Eventually peace was brokered, and credit is now shared between the two factions.Desktop Version
Bridge of Sighs in Venice, Italy
Bridge of Sighs in Venice, Italy
Beneath Venice"s Ponte dei Sospiri (Bridge of Sighs) is a popular place to kiss your beloved as a gondolier guides you through the city"s canals. But the sighs that the name refers to aren"t from staring into your darling"s eyes. The enclosed bridge, completed in 1600, connects the Prigioni Nuove (New Prison) to the interrogation rooms in the Doge"s Palace, and it is said that a prisoner"s last look at beautiful Venice would be from that bridge. And that"s reason enough to sigh indeed.Desktop Version
Fall Astronomy Week
Fall Astronomy Week
The Milky Way has billions of stars; among them, our own sun finds its place. The galaxy"s name is derived from the radiant, pale appearance of the band of stars and gas clouds that graces Earth"s sky. Methodical observations of the night sky started with early civilizations but astronomy, the oldest natural science, remains a source of fascination today. It"s what brings stargazers to Portugal"s Southwest Alentejo and Vicentine Coast Natural Park, a site free from heavy light pollution. Now"s a good time to seek out your own celestial spectacle, as it is Astronomy Week and the main event, Saturday"s Fall Astronomy Day, this year coincides with the autumnal equinox.Desktop Version

This colorful foursome resting on a tree limb during a winter in France is a group of great tits, one of the most common bird species seen across most of Europe and Asia and in parts of North Africa. Belonging to the same family as North American chickadees, great tits are beloved for their colorful plumage and acrobatic antics while feeding in backyards and in gardens, which makes them an ideal mascot for the Great Backyard Bird Count.Desktop Version

Batten down the hatches
The athletes on these boats are jockeying for position at the start of the Chicago Yacht Club Race to Mackinac Island (pronounced ‘Mack-i-naw’). The ‘Mac,’ at 333 miles long, is the world’s oldest and longest annual freshwater boat race. It’s an amateur event, but make no mistake, these sailors know their stuff. Many go on to race in the America’s Cup. This year’s race is held this weekend. The boats set sail—smallest to largest—just off Chicago’s Navy Pier, passing by the city skyline as we see in our image. When crews pass under the span of the mighty Mackinac Bridge—connecting the Lower Peninsula to the Upper Peninsula—Lake Michigan becomes Lake Huron, and the island appears.Desktop Version

Surf s always up in Paia
Old surfboards never die, at least not here, just outside the town of Paia, on Maui, Hawaii. Local resident Donald Dettloff constructed this fence beginning back in 1990 from over 600 discarded boards, most of which were either donated or salvaged from local junk and vintage stores. Dettloff originally wired some of his own boards to his fence to keep them from blowing away in a hurricane. Now the colorful display is a local landmark and even caught the attention of Guinness World Records for being the largest surfboard collection.Desktop Version
Arches National Park, Utah
Arches National Park, Utah
This stunning structure is Delicate Arch, the most famous of 2,000 stone arches scattered around Arches National Park in Utah. It is made up of Entrada Sandstone, the grains of which once formed a massive desert. They were cemented together by minerals, forming sandstone riddled with tiny holes. Over millennia, the rain seeped in and slowly dissolved the rock from the inside, forming these eye-catching sculptures. Most of the arches in the national park are formed from Entrada Sandstone and were once buried by other rock layers. They won"t last forever, but over time, new shapes will emerge from the layers of rock below to replace them. Every year, close to 1.4 million people visit the park to see Delicate Arch and this slowly shifting landscape for themselves.Desktop Version

Here at Flushing Meadows-Corona Park in Queens, New York City, it’s the opening day of the US Open Tennis Championships. When it began back in 1881 as the US National Championship, it was one of the first tennis tournaments in the world and was limited to amateur players only. It’s been through many iterations since, but this year marks the 50th anniversary of the modern competition, now called an ‘open’ because both amateurs and pros can compete. The US Open completes the fourth and final tournament of the international tennis Grand Slam, the world’s most prestigious pro tournaments.Desktop Version

To celebrate the start of Women"s History Month, our homepage photo features a candid shot of members of the US Army Nurse Corps in 1944. The women are shown in between training exercises while they await deployment to the South Pacific near the end of World War II. At the time, all who served in the Army Nurse Corps were women, and the units were all segregated. And though the need for nurses was urgent, the army had set a quota for just 160 Black nurses. By the end of the war, that number had increased to nearly 500.Desktop Version

The first San Diego Comic-Con (SDCC) was a single-day event for comic book fans on March 21, 1970. After that successful trial run, the organizers staged a three-day event featuring celebrity appearances later that year. Comic-Con grew quickly from a modest gathering of dedicated fans to the massive multimedia spectacle of SDCC that begins today. Each year, more than 100,000 Comic-Con attendees dress as their favorite characters from the books, television shows, and movies that they love.Desktop Version
Gifford Pinchot National Forest
Gifford Pinchot National Forest
Today we"re paying a visit to an "elder statesman" of the United States" national forests. Seen in today"s photo is Panther Creek Falls at Gifford Pinchot National Forest in Washington state. Officially, the forest was named in 1949 in honor of Pinchot, the first head of the US Forest Service. Located between Mount St. Helens to the west and Mount Adams to the east, the land was set aside as a place worth preserving as far back as 1897. But people had been living in the forest for more than 6,000 years. Archaeologists continue to make discoveries within the dense forest that teach us about the past lives of Native Americans.Desktop Version

We"re looking at the rooftop of Casa Batlló, a six-story building in the center of Barcelona topped with colorful "scales." What brings us here? Well, here in the Catalonia region of Spain, and in several other locales from England to Ethiopia, it"s the feast of Saint George. You know George (or Jordi, as the Catalans call him): He"s the knight who, legend holds, saved a much-loved princess by defeating a fierce dragon. It"s said the tower jutting from the casa"s tiled roof represents George"s lance thrust into the monster"s scaly back.Desktop Version
