10 Weird and Wonderful Bird Nests

It’s spring, and baby birds will soon be chirping in trees and rain gutters. But not all bird nests are created equal. Whether from mud, leaves, or saliva, here are 10 birds that make some of the most astounding structures in nature.

1. Sociable Weavers build giant haystacks in African trees.

This massive structure may look like a hay bale, but it’s actually a hive of nests. Like an apartment complex, it can house up to 400 Sociable Weavers. The thatched roof protects the birds in the South African or Namibian deserts by keeping the heat out by day and insulating from cold at night. Since the birds use the structure for generations, a nest can get up to 100 years old—that is, if it doesn’t break the tree limb first.

2. Malleefowl make giant mounds out of bird-made compost.

The nesting mound of the Australian Malleefowl is among the biggest in the world. The record was 15 feet high and 35 feet across, according to Guinness World Records. To make the mound, the male bird digs a hole and fills it with organic matter such as leaves, sticks, and bark. He even turns the compost to speed decay, just like a gardener. When the compost heats up to 89 to 93 degrees, the female lays up to 18 eggs on it, one at a time. The eggs are covered in sand. During incubation, the male regulates the temperature of the mound using his beak like a thermometer. Despite all this, Malleefowl abandon their chicks as soon as they’re born.

3. Golden-headed Cisticolas sew like tailors.

The Golden-headed Cisticola from Australia uses spiderwebs to sew a living canopy out of leaves. Since the bird’s nest is only 20 inches off the ground, the camouflage protects it from predators. To make the canopy, the bird pierces the leaves with its needle-like beak and pulls a “thread” through to hold them together. This cozy cover anchors the nest so that it stays hidden as the plant grows.

4. Black Kites use trash to decorate their nests.

Black Kites in Europe have adapted to humans by decorating their nests with strips of white plastic. While some scientists believe this is to camouflage the eggs, new research suggests that the plastic is really there to show off for other Black Kites. According to this theory, Black Kites view trash as a statement of power, like having a big house on a hill is to humans. Apparently, these birds take after people in more ways than one.

5. Edible-nest Swiftlets build nests out of saliva

In caves in Southeast Asia, Edible-nest Swiftlets make cliffside nests out of layers of their own spit. The saliva sticks to the rock and hardens in a bracket shape that the bird uses to lay its eggs. The nests are also a sought-after delicacy for bird’s nest soup. They have no flavor and no nutritional content, but this doesn’t prevent them from being one of the most expensive foods in the world. People are so crazy for it that many countries regulate the bird nest industry to keep the swiftlet from dying out.

6. Rufous Hornero nests look like outdoor ovens

The Rufous Hornero in South America is an ovenbird, so nicknamed because of how it makes its nest. The bird collects mud and manure and piles it into an upside-down bowl on a tree branch. The sun bakes the mud dry, making a sturdy structure resembling a clay oven. Since the birds build a new nest for every brood, there are often several mud nests in a row on the same branch, all made by the same birds.

7. Montezuma Oropendola nests look like hanging sacks.

These birds from Central America weave pendulous nests out of vines and banana fibers. The nests can be 3 to 6 feet long and look like a ball hanging in a stocking. Since the birds live in colonies, there can be up to 150 of these nests extended from one tree, although usually it's more like 30. The female takes 9 to 11 days to make her nest. The male often watches her work, and if he doesn't like what he sees, he'll tear it apart and make her start over.

8. One Gyrfalcon nest was around when Jesus was alive.

The Gyrfalcon (pronounced JER-fal-con) is a large white falcon that nests in cliffs in the Arctic. They use the same depression or scrape in the rock generation after generation. In 2009, researchers from the University of Oxford did radiocarbon dating on a Gyrfalcon nest and found that it was around 2500 years old. Three other nests were over 1000 years old, and fragments of gyrfalcon feathers were 600 years old. The birds have been continually using the nest since the Roman era.

9. Bald Eagle nests are huge.

In true American style, Bald Eagles make nests far bigger than their needs would seem to indicate. When they first mate, the eagles make smaller nests, or aeries, 50 to 125 feet above the ground by layering branches and sticks in a triangular pattern. Every year, they add more to the nest until it becomes big enough for a human to sit on. The largest bird nest on record was a Bald Eagle nest found in St. Petersburg, Florida in 1963. It was 10 feet wide and 20 feet deep.

10. Hummingbird nests are tiny (and adorable).

Wikimedia Commons

On the other end of the scale, hummingbird nests are so small that it’s easy to mistake them for knots in the trees. In fact, the smallest nest in the world is the Bee Hummingbird's nest, which is just over an inch wide. The hummingbird makes its cup-shaped nest by weaving spiderwebs with feathers and leaves to make it strong and stretchy, then covering the outside with lichen. The bird then lays two eggs, each the size of a coffee bean, inside. Awwww….

12 Facts About Theodore Roosevelt National Park

The only U.S. national park named after a person—America's 26th presidentTheodore Roosevelt National Park (TRNP) was established in North Dakota by Harry S. Truman in 1947. The park honors Roosevelt, who lived as a ranchman in the Dakota Territory in the 1880s and, as president, conserved 230 million acres of public land for future generations. Read on for things to do and see, plus what to know before you go camping, in Theodore Roosevelt National Park.

1. The plans for Theodore Roosevelt National Park began not long after Roosevelt’s death in 1919.

Medora, North Dakota, was chosen as the site of the memorial, and in 1921, the state’s legislature asked its reps in Congress to help set aside land for that purpose. One early proposal called for a park of more than 2000 acres, but that was controversial—the land was valuable to ranchers. Some believed a national monument was more appropriate than a national park.

Then, in the 1930s, drought and overgrazing led many homesteaders to abandon their land, which they sold to the federal government; some of those lands were set aside to create a park. In 1935, the land—which was in a north unit and a south unit—became the Roosevelt Recreation Demonstration Area, and in 1946, it was taken over by the Fish and Wildlife Service and became the Theodore Roosevelt National Wildlife Refuge.

On April 25, 1947, President Harry Truman signed the bill that created Theodore Roosevelt National Memorial Park; at that time, the land included the South Unit and the site of Roosevelt’s Elkhorn Ranch. The North Unit of the park was added the next year. Finally, in 1978, President Jimmy Carter signed a law that changed the memorial park to the Theodore Roosevelt National Park. In 2018, it received nearly 750,000 visitors.

2. Before the land became Theodore Roosevelt National Park, Native Americans hunted in the area.

A flint spearpoint and other projectiles from the Archaic Culture (5500 BCE to 500 CE) have been found in the park, as have artifacts from the Plains Woodland Tradition (1 to 1200 CE) and pre-Columbian peoples. Though one of the pre-Columbian sites includes a bison processing camp (or what remains of it), there was no permanent occupation of the area of that time, according to the park’s website.

There are a number of sites from what the website calls the Historic Period, which lasted from 1742 to the 1880s, and included artifacts like “stone rings, a rock cairn, and four conical, timbered lodges. Two of the lodges, presumably used by men engaged in seasonal eagle trapping, are still standing today … One archaeological interpretation indicated that the use of the badlands for hunting, gathering, and spiritual pursuits, though undertaken by numerous cultures and groups over millennia, had not significantly changed over that entire time span.” The Mandan and Hidatsa, among many other Native tribes, hunted in the area, and the lands have spiritual significance for some tribes as well.

3. Theodore Roosevelt National Park contains 70,488 acres.

The park is spread over three units. The South Unit, which is located in Medora off I-94, is its most visited area. The North Unit, 50 miles off the same highway, is more remote. Both units have scenic drives—though the drive in the South Unit is currently closed due to slumping—and hiking trails. The South Unit also has a petrified forest with a 10.3-mile trail.

The third unit of the park is its smallest, and very out of the way: The roads leading to the Elkhorn Ranch Unit are unpaved and sometimes require four-wheel drive. No roads go directly to the site to preserve the solitude TR would have felt living there, so getting to the site requires a bit of a walk along a mowed pathway.

4. Visitors to Theodore Roosevelt National Park can see the future president’s Maltese Cross ranch house.

When Theodore Roosevelt first came to the Dakota Badlands to hunt bison in 1883, he stayed with some cattle ranchers and decided to invest in a ranch himself. Before he left, he invested $14,000 into Maltese Cross Ranch. The cabin was built seven miles outside of Medora, and it was unusual for the area: While most houses were made of sod, Roosevelt’s ranch was made of ponderosa pine. It had a singled, pitched roof, which created an upper half-story where his ranch hands could sleep. There were three rooms (a kitchen, a living room, and a bedroom for TR), and white-washed walls.

The cabin got new owners in 1900, and after Roosevelt became president, it went on tour: It could be seen at the World’s Fair in St. Louis, Missouri, then to Portland, Oregon, for the Lewis and Clark Centennial Exposition. For a time, it sat in Fargo, North Dakota, and then on the state capital grounds in Bismarck. Finally, in 1959, the cabin came back to what was, by then, Theodore Roosevelt National Memorial Park. Today, it can be found in the South Unit of the Park behind the Visitor’s Center.

The building is mostly original; the roof and shingles were removed at one point and have been restored. Inside, visitors can see several authentic Roosevelt artifacts, including a traveling trunk with “T.R.” on the top and a hutch.

5. Visitors to Theodore Roosevelt National Park can go out to the site where Roosevelt’s second ranch house once stood.

In 1884, Roosevelt decided to abandon politics after the deaths of his wife and mother and settle at his ranch in the Dakotas permanently. But his Maltese Cross cabin was located on a popular route into Medora, and people were always stopping by. Grieving and seeking solitude, Roosevelt rode out to a site 35 miles north of Medora that had been recommended to him.

On the site, Roosevelt found the skulls of two elk, their horns interlocked, and named what he would come to refer to as his Home Ranch in their honor. He bought the rights to the site for $400; his nearest neighbors were at least 10 miles away.

Two friends of Roosevelt’s from Maine, Bill Sewall and Wilmont Dow, came to the Dakotas and built the 30-by-60-foot house of cottonwood pine; it had 7-foot high walls, eight rooms, and a veranda. Also on the site was a barn, a blacksmith’s shop, a cattle shed, and a chicken coop.

In Hunting Trips of a Ranchman, Roosevelt wrote:

“My home ranch-house stands on the river brink. From the low, long veranda, shaded by leafy cotton-woods, one looks across sand bars and shallows to a strip of meadowland, behind which rises a line of sheer cliffs and grassy plateaus. This veranda is a pleasant place in the summer evenings when a cool breeze stirs along the river and blows in the faces of the tired men, who loll back in their rocking-chairs (what true American does not enjoy a rocking-chair?), book in hand—though they do not often read the books, but rock gently to and for, gazing sleepily out at the weird-looking buttes opposite, until their sharp outlines grow indistinct and purple in the after-glow of the sunset."

But the cattle business was not meant to be Roosevelt’s future. He eventually returned to New York, and after a hard winter where he lost 60 percent of his herd, he sold the ranch in 1898. By 1901—the year Roosevelt became president—the ranch was gone. A local said that all that remained was “a couple of half-rotted foundations."

Today, visitors to TRNP can take a scenic drive on gravel roads, then hike three-eighths of a mile to the Elkhorn site, located between the Little Missouri River and black, white, and yellow Badlands bluffs. There, they can stand on the foundation stones that mark where TR’s Home Ranch once stood, listening to the birds, insects, and low mooing of cattle, as he would have done. (They might even encounter a cow or two on the trail!)

6. More than 185 species of birds have been spotted in Theodore Roosevelt National Park.

They include bald and golden eagles, blue-winged teal, American wigeon, turkey vultures, prairie and peregrine falcons, and the sage grouse. The park has a handy checklist [PDF] to help visitors keep track of the birds they’ve seen.

Birds aren’t the only animals you might see: TRNP is also home to elk, prairie dogs, pronghorns, feral horses, big horn sheep, coyotes, badgers, beavers, porcupines, mule deer, longhorn steers, rattlesnakes, and bison.

7. There are hundreds of bison in Theodore Roosevelt National Park.

Whether you call them bison or buffalo (though Americans use the terms interchangeably, there is a difference!), you’ll have a chance to see plenty of them at TRNP. Both the north and south units have herds—200 to 400 animals in the south and 100 to 300 in the north. Full-grown bison bulls can stand up to 6 feet tall and weigh up to 2000 pounds, so visitors should give them a wide berth or risk getting charged and possibly gored.

The American bison (Bison bison) was once critically endangered and nearly went extinct. (Roosevelt was one person who was instrumental in saving the species from extinction.) The animals were reintroduced into the park in 1956. Because all of the living bison are descended from a small number of animals, monitoring the genetic diversity of the herd is important. Every couple of years in October, park staff round up the animals in both units by using helicopters to herd them into progressively smaller enclosures. Eventually, each animal ends up in a squeeze shoot, where staff takes hair (for DNA analysis) and blood (to test for disease) samples and weighs and measures the animals. Bison born since the last roundup are given tags and microchips so they can be tracked.

8. Theodore Roosevelt National Park has a few prairie dog towns.

Black-tailed prairie dogs are abundant in TRNP. Roosevelt himself described them as “in shape like little woodchucks,” and called them “the most noisy and inquisitive animals imaginable.” Visitors can see the first of many prairie dog towns in the park near the Skyline Vista trail.

9. In prehistoric times, Theodore Roosevelt National Park was home to a Champsosaurus.

Fifty-five million years ago, during the Paleocene Epoch, North Dakota—including the area of TRNP—was a swamp, and in that swamp lived a reptile called Champsosaurus. The animal looked like modern-day crocodilians called gharials and could measure nearly 10 feet long.

10. You can go camping in Theodore Roosevelt National Park.

There are three campgrounds in TNRP, but visitors just can’t drive in and set up a tent—reservations must be made, fees must be paid, and, in some cases, permits are required to camp in the park.

Camping isn't the only thing you can do in the park: It's also possible to canoe or kayak down the Little Missouri River if the water is deep enough.

11. The colors of the rocks in Theodore Roosevelt National Park tell a story.

The massive and unusual formations in TRNP, created by erosion over millions of years, are awe-inspiring—and you can tell a lot about them from the colors of their layers [PDF]. Brown and tan layers indicate sandstone, siltstone, and mudstone, which came from the Rocky Mountains, while blue-gray is bentonite clay laid down by the ash of far-away volcanic eruptions. (The clay can absorb up to five times its weight in liquid, which is why it’s used in … kitty litter.)

Black is a layer of coal, and red is the delightfully named clinker, which is formed when coal veins catch fire and cook the rock above it. Locally, the red rock is called scoria, but clinker is its scientific name.

One coal vein located in the park caught fire in 1951 and burned for 26 years. Apparently, visitors could roast marshmallows over the fire, which finally burned out in 1977. Fires in the Badlands aren’t unusual; they can be caused by lightning strikes or even set purposefully to reduce hazards or benefit certain species.

12. There are a number of interesting historic sites near Theodore Roosevelt National Park.

While you’re in the area, check out the Chateau de Mores—the mansion that was home to a French marquis who dreamed of bringing a cattle-slaughtering business to Medora—and the Von Hoffman House. And don’t miss the Medora Musical, a variety show held in an open-air amphitheater that features the history of the town’s most famous and infamous figures—plus an appearance by the president who once called the area his home.
