According to researcher Kaeli Swift of the University of Washington's Avian Conservation Laboratory, crows hold "funerals." When they see a corpse of their own kind they gather together and squawk loudly. To determine what they may be doing, Swift displayed a taxidermied dead crow to other crows. On some days though, she wore a creepy mask and wig. After multiple experiments with and without her disguise or the dead bird, the crows appeared to remember "the experience with the mask and dead crow and now connected the area with danger." From Deep Look:
And here’s what Swift said makes that really interesting: These new mobs (she encountered even weeks later) contained crows that had never seen the masked Swift with the dead crow. But they still learned to avoid the masked figure.
Learning directly from each other, rather than through individual experience, is called social learning.
“By participating in these funerals, crows can get information about new dangers without taking the risk,” Swift said.
Astronaut David Scott re-created, in 1971 during the Apollo 15 mission, Galileo’s “falling bodies” experiment by dropping a hammer and feather on the moon at the same time. Simply, both fell at the same rate because there was no air resistance. screengrab via Wonders of Physics/YouTube (Digg)

When you see that curved arrow on the side of a cardboard box, you instantly know that box came from Amazon. The unfurled rainbow feathers of a peacock immediately scream NBC. And a partially eaten piece of fruit in the profile is a world-recognized symbol of tech titan Apple. Icons are powerful symbols, condensing volumes […]
Call it retro. Call it a throwback. Even call it kitsch. But the 80s are still a singular time in pop culture history. From Ghostbusters and Back to the Future to your neighborhood arcade and the Atari 2600, artifacts of that seminal decade still resonate, evoking audible excitement and sighs of pleasant yesteryear remembrance. But […]
