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….

By this point, your eco-friendly pal probably has a reusable water bottle that accompanies them everywhere and some sturdy grocery totes that keep their plastic-bag count below par. Here are 10 other sustainable gift ideas that’ll help them in their conservation efforts.

1. Reusable Produce Bags; $13

No more staticky plastic bags.Naturally Sensible/Amazon

The complimentary plastic produce bags in grocery stores aren’t great, but neither is having all your spherical fruits and vegetables roll pell-mell down the checkout conveyor belt. Enter the perfect alternative: mesh bags that are nylon, lightweight, and even machine-washable.

2. Animal Tea Infusers; $16

Nothing like afternoon tea with your tiny animal friends.DecorChic/Amazon

Saying goodbye to disposable tea bags calls for a quality tea diffuser, and there’s really no reason why it shouldn’t be shaped like an adorable animal. This “ParTEA Pack” includes a hippo, platypus, otter, cat, and owl, which can all hang over the edge of a glass or mug. (In other words, you won’t have to fish them out with your fingers or dirty a spoon when your loose leaf is done steeping.)

Buy it: Amazon

3. Rocketbook Smart Notebook; $25

Typing your notes on a tablet or laptop might save trees, but it doesn’t quite capture the feeling of writing on paper with a regular pen. The Rocketbook, on the other hand, does. After you’re finished filling a page with sketches, musings, or whatever else, you scan it into the Rocketbook app with your smartphone, wipe it clean with the microfiber cloth, and start again. This one also comes with a compatible pen, but any PILOT FriXion pens will do.

4. Food Huggers; $13

It’s hard to compete with the convenience of plastic wrap or tin foil when it comes to covering the exposed end of a piece of produce or an open tin can—and keeping those leftovers in food storage containers can take up valuable space in the fridge. This set of five silicone Food Huggers stretch to fit over a wide range of circular goods, from a lidless jar to half a lemon.

5. Swiffer Mop Pads; $15

Swiffers may be much less unwieldy than regular mops, but the disposable pads present a problem to anyone who likes to keep their trash output to a minimum. These machine-washable pads fasten to the bottom of any Swiffer WetJet, and the thick microfiber will trap dirt and dust instead of pushing it into corners. Each pad lasts for at least 100 uses, so you’d be saving your eco-friendly friend quite a bit of money, too.

6. SodaStream for Sparkling Water; $69

A fondness for fizzy over flat water doesn’t have to mean buying it bottled. Not only does the SodaStream let you make seltzer at home, but it’s also small enough that it won’t take up too much precious counter space. SodaStream also sells flavor drops to give your home-brewed beverage even more flair—this pack from Amazon ($25) includes mango, orange, raspberry, lemon, and lime.

7. Washable Lint Roller; $13

Each one also comes with a 3-inch travel-sized version, so you can stay fuzz-free on the go.

8. Countertop Compost Bin; $23

Like a tiny Tin Man for your table.Epica/Amazon

Even if you keep a compost pile in your own backyard, it doesn’t make sense to dash outside every time you need to dump a food scrap. A countertop compost bin can come in handy, especially if it kills odors and blends in with your decor. This 1.3-gallon pail does both. It’s made of stainless steel—which matches just about everything—and contains an activated-charcoal filter that prevents rancid peels and juices from stinking up your kitchen.

Buy it: Amazon

9. Fabric-Softening Dryer Balls; $17

Also great for learning how to juggle without breaking anything.Smart Sheep

Nobody likes starchy, scratchy clothes, but some people might like blowing through bottles of fabric softener and boxes of dryer sheets even less. Smart Sheep is here to offer a solution: wool dryer balls. Not only do they last for more than 1000 loads, they also dry your laundry faster. And since they don’t contain any chemicals, fragrances, or synthetic materials, they’re a doubly great option for people with allergies and/or sensitive skin.

Buy it: Amazon

10. Rechargeable Batteries; $40

Say goodbye to loose batteries in your junk drawer.eneloop/Amazon

While plenty of devices are rechargeable themselves, others still require batteries to buzz, whir, and change the TV channel—so it’s good to have some rechargeable batteries on hand. In addition to AA batteries, AAA batteries, and a charger, this case from Panasonic comes with tiny canisters that function as C and D batteries when you slip the smaller batteries into them.
