I’m not going to summarize this article. I am just going to leave this here:
“What happens next may upset you (and in fact, if you’re sensitive to bird-on-bird violence, you may want to stop reading here). Before the chicks even realize there’s an enemy at the gates, the woodpecker cocks its head back and starts to peck … their skulls. The Gila’s head moves like a pneumatic hammer, up and down, up and down, drilling into flesh and bone with the force of 1,000 G’s. Soon both chicks’ skulls have been opened up like coconuts. At this point, the woodpecker begins extracting brain and blood with its long, sticky tongue.”

WARNING: This video is not for the faint of heart. It’s gruesome to watch if you love little baby birds. You’ve been warned.
Since birds are dinosaurs, we have long assumed the quick way that birds exit their shell was mimicked in their much larger and significantly more extinct brethren.
However, it turns out that it takes much longer (3-6 months) for a dinosaur to exit its shell.
Why does that matter? Well it might have put them at a disadvantage relative to faster producing animals, like mammals and modern birds.
Curious how scientist figured it out (No, they didn’t clone dinosaurs like Jurassic Park… yet)? Check it out over at Science.
I don’t mean that we’re heading into the Age of the Octopus (although see here, and prepare for our cephalopod overloads).
But rather, the lifespan and ageing of octopuses is kind of odd.

Not underground as in it burrows into the earth, but the formal noun referring to the London Underground. That’s right, as well as being an exceptional form of public transportation, the London Underground has it’s very own species of mosquito.
It was first reported during World War Two, when the tunnels of the Underground were used as overnight shelters, housing 180,000 people.
And then it was largely forgotten until a doctoral student, Katharine Byrne, started studying this subterranean pest. And found that the Underground mosquito is no longer able to interbreed with other mosquitoes:
“There are differences in both the mating behaviour and the reproductive biology,”

Sure, finding new and interesting species and describing them is exciting.
But finding new bacteria that cause a well understood disease? Equally if not more exciting (my little parasitic loving heart is all aflutter!).
While it has long been thought that lyme disease is caused by one bacterium (Borrelia burgdorferi), researchers at Mayo Clinic found something floating around in blood samples of people suspected of having Lyme disease that is totally different.
It has been named Borrelia mayonii, and it is remarkably similar to it’s lyme disease causing brethren. But it also has some important differences.

Domesticated animals are the product of unnatural selection. To view some of the unnatural diversity in turkeys – check out Porter’s Rare Heritage Turkeys. They have the Sweetgrass, the Chocolate Slate, the White Holland, the Red Phoenix, and – my personal favorite – the Pencilled Palm (amongst many more varieties). They even have information on feather color genetics and what makes a (Heritage) turkey a (Heritage) turkey. Happy Turkey Day!
Is that a White Holland I see?

The Mississippi River that we know today is a creation of the army corps of engineers. Before they got to levying, dredging and damming it into submission, it was a wild and meandering thing that harbored great concentrations of wildlife. One component of that was a massively abundant shrimp with an amazing life cycle:
It turned out that in pre-colonial times the shrimp traveled all the way north into the upper reaches of the Mississippi’s main eastern tributary, the Ohio River, and back again – a 2,000-mile round trip. It was a journey more amazing than similarly epic migrators like salmon. For whereas adult salmon may have an equally long journey to their upstream spawning sites, it is the quarter-inch juvenile shrimp that swim and crawl 1,000 miles upstream against the strong currents of the Mississippi.
What happened to these shrimp? Go read the story to find out.
