Why do Ants walk in a Line?
When I woke up one summer morning, I noticed a string of dashes on my bedroom wall. The line ran from the ceiling to the wall behind my bed and then disappeared under it. As I watched, I saw one of the dashes move. It was a small red ant walking up the line. Soon, another one followed and then another, till it grew into an army of ants marching up the wall. I noticed that while walking in a line the ants were cleaning the wall paint underneath them and, in the process, making a path....
The Boy with a Catapult
Our class at school has an odd assortment of boys. There was Harbans Lal who, when asked a difficult question, would take a sip out of his inkpot because he believed it sharpened his wits. If the teacher boxed his ears he would yell, “Help! Murder!” so loudly that teachers and boys from other classes would come running to see what had happened. This caused much embarrassment to the teacher. If the teacher tried to cane him, he would put his arms round him and implore, “Forgive me, Your Majesty!...
Dinosaur eggs Found in Patagonia
The film Jurassic Park is peanuts compared to this: Last month, Argentine scientists found thousands of dinosaur eggs in hundreds of nests at Patagonia. A report in the journal New Scientist says that it is the biggest nesting site of dinosaurs found thus far. Each nest contained 15 to 30 eggs the size of a grapefruit each. The eggs contained bones of titanosaurs which would have weighed about 15 tonnes when fully grown. Close to 100 million years old dinosaur egg....
Why are Eggs Oval?
Have you ever climbed a tree and peeked into the nest of a crow or a sparrow? Or looked into that flowerpot where the noisy pigeon decided to lay its eggs? The sight of a mother hen sitting on a bunch of fresh white eggs is great, though most of us see them only when they land on the breakfast table every now and then. Eggs come in different colours. They may be blue, blue-green, yellow, spotted, blotched or white....
What kind of Family Life did the Dinosaurs Have?
In Argentina this year, scientists digging on a site made a fantastic discovery, which made them realise that dinosaurs lived as a large family. The site consisted of many nests with each nest containing as many as 15 to 30 eggs. The eggs belonged to a plant-eating dinosaur called Titanosaurs. It is the biggest nesting site of dinosaurs found so far. The word dinosaur is a Greek word meaning giant reptile. Most reptiles lay eggs in nests but they walk away after the young hatch to fend for themselves....
Do Some Animals Farm?
We all live the way we do in villages and cities because a long, long time ago, the early humans gave up hunting for farming. They domesticated plant species by cultivation, ploughed the land and harvested the grain. That was the beginning of civilisation as we understand it. But, do you know that certain ant species were actually farming fungus years before humans learnt how to farm? For many millions of years, ants belonging to the attines group were farming and cultivating fungi in their anthill nests....
The Nest
Common Birds Written by Salim Ali and Laeeq Futehally Published by National Book Trust, New Delhi Think of birds and you think of Dr. Salim Ali, India’s most famous ornithologist. He is the scientist who succeeded in communicating his passion for studying bird life in India to the ordinary Indian. Generations of Indians have grown up on his wonderfully warm and crisp writings on birds and have squealed in delight on being able to distinguish a red turtle dove from a spotted dove....
