How Did You Know? - {day 3}

Play for your chance to WIN a $100 shopping spree in our store!

We're back with another 5-day trivia hunt!

First let's meet our current champion, and big $100 winner, Daniel Wilson. You can read all about him and see the answers to last month's final puzzle here.

As comments have been turned off for the length of the 5-day hunt, be sure to hit us up via e-mail with questions if you find something in the instructions unclear.

As always, it pays to play whether you're the first in with all the correct answers or not. In addition to the $100 shopping spree first-prize, we're also giving away a $50 shopping spree in our store to one random winner who has all the right answers but isn't the first to e-mail them in. Random winners sometimes submit all the correct answers/logic a full 48 hours after the closing bell, so don't worry if you're late or can't submit your final answers at 8 pm ET next Monday.

Have fun with it, and, as always, don't hesitate to work in teams and e-mail all your friends for help. Many, if not most of our past HDYK winners have been teams, not individuals.

If you're new to the 5-day trivia hunt, be sure to see the rules and regulations page here. Also, we've now got a Facebook page which we're going to use to drop cryptic clues now and then. Don't worry, even if you're not a Fan of our Facebook page, you can still view it through the link below, and, of course, you'll still be able to solve all the puzzles, as normal, even if you don't want to visit Facebook. But the Fan page will allow you to friend other contestants, form alliances, network and just hang out with other trivia nuts. So go check it out over here.

If you missed Day 1, you can see that right here, while Day 2 is is over here Now on to our second challenge!

Why Can Parrots Talk and Other Birds Can't?

If you've ever seen a pirate movie (or had the privilege of listening to this avian-fronted metal band), you're aware that parrots have the gift of human-sounding gab. Their brains—not their beaks—might be behind the birds' ability to produce mock-human voices, the Sci Show's latest video explains below.

While parrots do have articulate tongues, they also appear to be hardwired to mimic other species, and to create new vocalizations. The only other birds that are capable of vocal learning are hummingbirds and songbirds. While examining the brains of these avians, researchers noted that their brains contain clusters of neurons, which they've dubbed song nuclei. Since other birds don't possess song nuclei, they think that these structures probably play a key role in vocal learning.

Parrots might be better at mimicry than hummingbirds and songbirds thanks to a variation in these neurons: a special shell layer that surrounds each one. Birds with larger shell regions appear to be better at imitating other creatures, although it's still unclear why.
