How Birds-To-Be Get Oxygen Inside Eggs

Your body needs oxygen to function — and that was true even before you were born. As you grew inside your mother’s womb, even before you had working lungs, your cells were crying out for oxygen. And your mother kindly answered that call. Oxygen and nutrients from her blood made their way down your umbilical cord, through your belly button, and fueled your body.

Now consider a chick — before it has hatched. It’s cut off from its mother by a hard shell and a couple membranes. There’s no way for the hen to get her still-developing offspring the oxygen it desperately needs; the pre-hatchling is on its own.

So why don’t bird embryos suffocate inside their eggs?

In Skunk Bear’s newest episode, we use the magic of animation to take you inside an egg and explore the delicate system that keeps these little things alive.

A bird’s eye view: Songbirds perceive colour like humans

Faced with a glorious spectrum of colour, songbirds, just like humans, look for the big picture.

“Faced with a glorious spectrum of colour, songbirds, just like humans, look for the big picture.

They can lump nearby hues in the colour spectrum into categories, such as shades that are generally red, or generally orange.

A study now shows that this affects their ability to distinguish between certain colours.

The findings, by a team from Duke University in North Carolina, are published in the journal Nature. “

All life on Earth, in one staggering chart

From Vox

“All life on Earth, in one chart

What you’ll see below is a kind of tower of life. Each large block of this tower represents a gigaton of life, and the blocks are grouped into broad kingdoms. There are the protists (think microscopic life like amoebae), archaea (single-celled organisms somewhat similar to bacteria), fungi (mushrooms and other types of fungus), bacteria (you’re familiar with these, right?), plants, and animals.

As you can see, plants dominate our world. If the tower of life were an office building, plants would be the main tenants, taking up dozens of floors. Comparatively, all the animals in the world — seen in gray in the tower — are like a single retail shop (a trendy one, to be sure) on the ground floor.” – from vox.com
