This is the Three Wattled Bell Bird, recorded in Costa Rica, Central America.

Because of the secretive behavior of this bird, it is often only detected by the distinctive bell-like call given by the males. At close range, the vocalization of many in Costa Rica is heard as a complex three-part song, the “bonk” giving the bird its name. This hollow, wooden “bonk” is thought to be among the loudest bird calls on Earth, audible to humans from over 0.5 mi (0.80 km) away. 

Watch a phenomenal amount of videos with birds, including more that either look or sound quite unusual: the common potoo, the red-capped manakin, the not-to-be-missed birds of paradise, and the kookaburra. 

Nothing like a Friday for some birdwatching (without even leaving your desk)! How does that huge sound come from such a tiny creature?! Did it swallow a klaxon?

If you are any good with those old “magic eye” posters and interested in anatomy, check out vovel123’s incredible gallery of stereogram CT scans. There are nearly 700 incredibly cool stereograms waiting to be seen in all their 3D glory.

These take a little practice to get right, but luckily after several years of reading biochemistry papers I can do stereograms in my sleep (you biochemists and crystallographers out there know what I’m talkin’ about, right?).

Click the images to make them big, for starters. If you allow your eyes to cross a little, then the two outside images will cross over in the center. Relax your eyes there and don’t fight the weirdness. You’ll be seeing 3D before you know it!

The full gallery is way too much fun.
