Birds are very clever animals. They exhibit a wide range of smart behaviors, including good memories, extensive communication, planning for the future, and remembering the past. Some birds can solve problems, and others are capable of adapting to new environments and conditions.

Experts often think of intelligence in terms of creative abilities used to solve problems. Some scientists believe that tool-using birds show such abilities. The woodpecker finch (first from left) of the Galapagos Islands, for example, has learned to use a cactus spine or small twig as a probe to remove carpenter bee larvae from their tunnels. The Egyptian vulture (second from left) uses rocks to break open ostrich eggs. Gulls learn to drop clams and turtles onto roc ...

Ever wondered why traditional ballpoint pens are capped with a vent? If you search online, you'll find several theories as to why, from the outrageous being that it prevents suffocation if a child were to inhale it, to the possibility that the company made it purposefully to dry out the ink and make the user buy a new pen.

Others have even suggested a greater science behind it, saying that the hole either creates the same level of air pressure inside and outside of the pen, allowing the ink to flow into the point, or to make it easier to remove the cap.

It turns out that one of these claims is actually true, can you guess which one?

According to the website of the ballpoint pen inventor, BIC writes that "all our BIC caps comply with internati ...

You probably wouldn't associate Canada with having any deserts, since the country is typically attributed with winters that are long and harsh. However, that's not entirely true if you visit the southern region of Osoyoos, British Columbia, Canada, known as the Okanagan Desert. In this area, summer temperatures regularly exceed 38˚C (100 °F), and portions of the area receive roughly 250 to 300 mm (10 to 12 inches) of rain per year – compare that to Vancouver, which receives approximately 1120 mm (43 inches) of rain per year.

While some areas in British Columbia experience hotter summer temperatures and are at least as arid, the South Okanagan area is home to several species of plants and animals that are not found elsewhere in Canada. For e ...

The Falkland Islands is an archipelago (meaning a cluster of smaller islands) in the South Atlantic Ocean, 300 miles (483 kilometres) east of Argentina.


The 700+ islands have a combined area of 4,700 square miles (12,000 square kilometers), with a population of approximately 4,500 people. The Islands economy is largely based on sheep farming, with an emphasis on high-quality wool exports. The current sheep population scattered throughout the land exceeds 500,000, which equates to roughly 111 sheep per person; per capita, that's 106 sheep per square mile (41.6 per square kilometer). Since the Islands are located north of Antarctica, sheep farming had to have been introduced at some point in history. Early settlers who were of British origin ...

1. Each year in the United States, there are approximately six million pregnancies. This means that at any one time, about 4% of women in the United States are pregnant.

2. About 3% of all pregnant women will give birth to twins, which is an increase in rate of nearly 60% since the early 1980s.

3. Approximately 500,000 babies are born each year in the United States to teenage mothers.

4. The largest baby ever born weighed more than 23 pounds but died just 11 hours after his birth in 1879. The largest surviving baby was born in October 2009 in Sumatra, Indonesia, and weighed an astounding 19.2 pounds at birth.

5. Approximately one in three babies in the United States is now delivered by cesarean section. The number of cesarean sections in the Un ...

1)  Roman Numeral IV

Although the Roman numeral for the number 4 has always been taught to have been "IV," according to historians, the ancient Romans probably used "IIII" most of the time. This is partially backed up by the fact that early grandfather clocks displayed IIII for the number 4 instead of IV. Early clockmakers apparently thought that the IIII balanced out the VIII (used for the number 8) on the clock face and that it just looked better.

2)  Base 60

The Babylonians wrote numbers in a system that used 60 as the base value rather than the number 10. They did not have a symbol for "zero."

3)  Fraction Bar

The Romans did not use numerals to indicate fractions but instead used words to indicate parts of a whole. It wasn't until later in h ...

The coconut crab (Birgus latro) is a species of terrestrial hermit crabs that's known for the largest land-living arthropod in the world, weighing up to 4.1 kg (9.0 lb). It is found on islands across the Indian Ocean and parts of the Pacific Ocean, mirroring the distribution of the coconut palm. Like other hermit crabs, juvenile coconut crabs use empty gastropod shells for protection, but the adults develop a tough exoskeleton on their abdomen and stop carrying a shell.

Coconut crabs have evolved organs known as branchiostegal lungs, which are used instead of the vestigial gills for breathing. They cannot swim, and will drown if immersed in water for long. They have also developed an acute sense of smell, which has evolved convergently with ...
