"An IQ Too High?"

I’m not sure which is more incredible… The crow figuring every single thing out, or this dude setting up this whole thing. 🤯 Boggles my mind!

The crow bringing the chicken nugget to mark's shrine:
1) made me cry
2) may be the first time ive seen an animal develop a religion

I wasn't actually surprised that she could complete any of the puzzles individually - they're all things crows are known to be able to do - but I was blown away by her ability to understand (immediately?) that she was completing a series of puzzles, that she should follow the lights, and that the puzzles were linked together.

The coolest part imo is when the crow tries to take shortcuts to solve the problems faster. Really shows they understand the end goal and aren't just repeating actions mindlessly.

Dude a crow bending the tip of metal to pull out the bucket and then retrieving the same bucket to complete the next puzzle is just mind bending to me!!

When Cheryl went out of her way to not only dip the nugget in the “water sauce” but then offer that nugget to Mark’s portrait I may or may not’ve shed a tear

The last part with the crow giving the nugget is just so wholesome.

Wow, those wild crows trained Mark perfectly to leave them nuggets on the porch!

At 15:20 when she brings the wooden ball over to the scale, I think rather than thinking the ball is heavier than the coins, she almost immediately (and correctly, excepting a few puzzles) understands that things from the previous puzzles are important for the next. She might have thought the wooden ball was required to solve the scale.

At first when I saw the puzzles, I was thinking ''there's no way a crow can do all that''. To say my mind has been blown is a gigantic understatement

My dad ended up getting trained by the neighborhood crows to do tricks for them... One day he noticed the crows throwing walnuts to the ground, clearly trying to break them but without much success, so he picked up the walnuts, stomped on them until they broke, and put them on the sidewalk for the crows. He did that a few more times on separate occasions, and the next thing he knew, the crows were waiting for him just to drop walnuts straight under his feet when he was passing by. They'd call him to get his attention if he didn't notice them. They trained him very well indeed... :)

You mentioned the crows throwing nuts in front of cars to open them. I have seen a fun variation on this. When I was a royal guard, and walking guarding outside a particular castle, the crows had noticed that we walked very particular routes, so particular that you can actually see the routes as the stones are more worn there. We had steel under our boots to make sound, and they would throw their nuts on my route, using me as they do cars to open their nuts.
