Amsterdam Hopes to Save Bee Populations With Its 'Insect Hotels'

While the U.S. bee population fell by 23 percent between 2008 and 2013, the Netherlands is abuzz with activity. Within that country, bees have multiplied by 45 percent since 2000, and this isn’t by accident. As NBC reports, “insect hotels” and plants that are known to attract bees and butterflies have been strategically placed around Amsterdam in recent years.

According to Netherlands-based entomologist Jo-Lynn Teh-Weisenburger, insect hotels are “considered to be the urban solution to declining populations of beneficial insects in human environments due to habitat loss, pollution, and abuse of pesticides.” They’re often made from wooden pallets and feature small tubes where bees can nest.

The rise of wild bee and honeybee populations in Amsterdam has also been linked to a ban against chemical pesticides on public land. A study from last year found that one widely used pesticide makes it harder for bees to fly on target.

The decline of the bee—an important pollinator—has been a growing concern around the world. "Insects are very important because they’re the start of the food chain," Geert Timmermans, an ecologist who works for the city of Amsterdam, told NBC. "When it goes well with the insects, it also goes well with the birds and mammals."

Insect hotels have also proven popular in Canada, with one conservation group setting up more than 400 bee habitats in Alberta. The “hotels” are easy enough to make, but Teh-Weisenburger warns that there’s a right and a wrong way to go about it. So if you’re looking to take on a DIY insect hotel project, check out her article for tips first.

Aspiring Eagle Scout Is Turning Old Fire Hoses Into Hammocks for Big Cats

Boy Scouts have to demonstrate skills in multiple areas to graduate to the rank of Eagle Scout. On his quest to reach the top rank in scouting, eighth-grader Payton Crawford is doing something that's unusual for the organization: Knitting hammocks for senior big cats out of old fire hoses, CBS Denver reports.

For his Eagle Scout project, the 11-year-old boy from Colorado wanted to help the Wild Animal Sanctuary in Keenesburg, Colorado. The nonprofit rescues large carnivores from abusive situations and gives them a new home in a 10,000-acre wildlife refuge. There are more than 500 animals living at the site.

When they're not roaming the sanctuary, older big cats like lions, tigers, and leopards will be able to lounge on Crawford's supportive hammocks. He gathered old hoses from fire departments, cut them into the desired lengths, and wove them into hammocks big enough to accommodate a variety of animals. He can make one himself in about two hours, but he needs help carrying the final product.

“It’s just something different that I wanted to try out,” he told CBS. “Give them a better life because they don’t have the luxury we do.”

You can see how Crawford put them together in the video below.

20 Black-and-White Facts About Penguins

Who is a penguin's favorite family member? Aunt Arctica! 

We kid! But seven of the 17 species of penguins can be found on the southernmost continent. Here are 20 more fun facts about these adorable tuxedoed birds. 

1. All 17 species of penguins are found exclusively in the Southern Hemisphere.

2. Emperor Penguins are the tallest species, standing nearly 4 feet tall. The smallest is the Little Blue Penguin, which is only about 16 inches.

3. The fastest species is the Gentoo Penguin, which can reach swimming speeds up to 22 mph.

4. A penguin's striking coloring is a matter of camouflage; from above, its black back blends into the murky depths of the ocean. From below, its white belly is hidden against the bright surface.

5. Fossils place the earliest penguin relative at some 60 million years ago, meaning an ancestor of the birds we see today survived the mass extinction of the dinosaurs.

6. Penguins ingest a lot of seawater while hunting for fish, but a special gland behind their eyes—the supraorbital gland—filters out the saltwater from their blood stream. Penguins excrete it through their beaks, or by sneezing.

7. Unlike most birds—which lose and replace a few feathers at a time—penguins molt all at once, spending two or three weeks land-bound as they undergo what is called the catastrophic molt.

8. All but two species of penguins breed in large colonies of up to one thousand birds.

9. It varies by species, but many penguins will mate with the same member of the opposite sex season after season.

10. Similarly, most species are also loyal to their exact nesting site, often returning to the same rookery in which they were born.

11. Some species create nests for their eggs out of pebbles and loose feathers. Emperor Penguins are an exception: They incubate a single egg each breeding season on the top of their feet. Under a loose fold of skin is a featherless area with a concentration of blood vessels that keeps the egg warm.

12. In some species, it is the male penguin which incubates the eggs while females leave to hunt for weeks at a time. Because of this, pudgy males—with enough fat storage to survive weeks without eating—are most desirable.

13. Penguin parents—both male and female—care for their young for several months until the chicks are strong enough to hunt for food on their own.

14. If a female Emperor Penguin's baby dies, she will often "kidnap" an unrelated chick.

15. Despite their lack of visible ears, penguins have excellent hearing and rely on distinct calls to identify their mates when returning to the crowded breeding grounds.

16. The first published account of penguins comes from Antonio Pigafetta, who was aboard Ferdinand Magellan's first circumnavigation of the globe in 1520. They spotted the animals near what was probably Punta Tombo in Argentina. (He called them "strange geese.")

17. An earlier, anonymous diary entry from Vasco da Gama's 1497 voyage around the Cape of Good Hope makes mention of flightless birds as large as ducks.

18. Because they aren't used to danger from animals on solid ground, wild penguins exhibit no particular fear of human tourists.

19. Unlike most sea mammals—which rely on blubber to stay warm—penguins survive because their feathers trap a layer of warm air next to the skin that serves as insulation, especially when they start generating muscular heat by swimming around.

20. In the 16th century, the word penguin actually referred to great auks (scientific name: Pinguinus impennis), a now-extinct species that inhabited the seas around eastern Canada. When explorers traveled to the Southern Hemisphere, they saw black and white birds that resembled auks, and called them penguins.
