This falcon-cam view as the predator hunts a crow is incredible — but just as incredible is the old sailing illusion it's using to do so.
We're still working on understad how animals detect magnetic fields, but what's going on in their brains to make sense of it all? Researchers have discovered the part of pigeon's brain that can process magnetic signals they detect, and it's enough to direct them travelling across the globe.
Humans likely first took to the seas about 50,000 years ago. But there's mounting evidence that our Neanderthal cousins were routinely sailing throughout the Mediterranean twice as long ago. Alternatively, they were just really good at long distance swimming.
Before the invention of modern navigational equipment, ancient sailors crossed the seas largely through their knowledge of the positions of the Sun and stars. So how did Vikings cross from Europe to America in the often foggy, cloudy northern Atlantic?
In 1492, Christopher Columbus landed in what is now the Bahamas, changing the world forever. But was he first non-indigenous person to reach the Americas? Vikings got there before him, and possibly Polynesians too...and those are just the sane theories.
Vikings did a lot of navigating in their line of work. Those who didn't know how to use the sun to get exactly where they wanted to go would end up razing only sandcastles, pillaging only bird's nests, and setting fire only to their own beards. So when cloudy, foggy, gray days caused these intrepid seamen to tear the…
