DID YOU KNOW!?

Bird that barks instead of sings

The Antpitta avis canis Ridgley is a bird that looks like a stuffed duck on stilts and barks like a dog. The bird was discovered by ornithologist Robert S. Ridgley in the Andes in Ecuador in June 1998. Thirty of these long-legged, black-and-white barking birds were found. It apparently had gone undetected because it lives in remote parts and, of course, doesn’t sing. The size of a duck, it is one of the largest birds discovered in the 20th Century.

There also are dogs that do not bark! The basenji, smallish dog with a silky copper coat, does not bark. Instead, it yodels when it get excited. Wild dogs like the African Wild Dog also do not bark

 

Cow burps and global warming

Cows and global warming

With all its grazing and many stomachs, it is no wonder that cows are one of the main contributors to the hole in the ozone layer. Apart from CFC, the biggest culprit is hydrocarbon emissions from cars and cows. Yes, cows! Cows release some 100 million tons of hydrocarbon annually – by releasing gas. To give you an idea of how much gas a cow emits: if the gas of 10 cows could be captured, it would provide heating for a small house for a year.

But unlike what you think, cows release hydrocarbon mostly by burping.

 

  

If blood is red, why are veins blue?
Blood is bright red in its oxygenated form and a dark red in deoxygenated form. In simpler terms, it is bright red when it leaves the lungs full of oxygen and dark red when it returns to the lungs for a refill. Veins appear blue because light penetrating the skin is absorbed and reflected in high energy wavelengths back to the eye. Higher energy wavelengths are blue.

Why is blue for boys and pink for girls?
In ancient times, it was believed that certain colors could combat the evil spirits that lingered over nurseries. Because blue was associated with the heavenly spirits, boys were clothed in that color, boys then being considered the most valuable resource to parents. Although baby girls did not have a color associated with them, they were mostly clothed in black. It was only in the Middle Ages when pink became associated with baby girls.

Why do onions make you cry?
Onions, like other plants, are made of cells. The cells are divided into two sections separated by a membrane. One side of the membrane contains an enzyme which helps chemical processes occur in your body. The other side of the membrane contains molecules that contain sulfur. When you cut an onion, the contents on each side of the membrane mix and cause a chemical reaction. This reaction produces molecules such as ethylsufine which make your eyes water.
To prevent crying when you cut an onion, cut it under a running tap of cold water. The sulfur compounds dissolve in water and are rinsed down the sink before they reach your eyes. You can also put the onion in the freezer for ten minutes before you cut it. Cold temperatures slow down the reaction between the enzyme and the sulfur compounds so fewer of the burning molecules will reach your eyes.

hope you enjoy :)
