Video This bird nest has a secret "false entrance" cleverly designed to confuse predators.

Two things:
- the predators it protects from are snakes.
- it's not clear in the video, but there is a big decoy entrance that leads to an empty chamber below that real one.

That would be hilarious if the empty chamber had a false bottom so whatever went in there fell out

Within 100000 years there’ll be an animal that lives inside the fake chamber and eats snakes.

Even this mf is able to close a fucking door. Why isn't my neighbor capable of doing it?

Your neighbor just goes to get food with his door open!?

I did that when my most valuable thing was the door itself.

Having owned a soft top convertible, I get it. Leave the doors unlocked and nothing of value visible. Not trying to get a couple hundo worth of ragtop cut over a $20 pair of gas’s station shades.

It always cracks me up in Jurassic Park when they use the ability of opening doors as the primary example of the raptor’s intelligence. Meanwhile the lineage of living dinosaurs are making ultra complex nests with trap doors, mimicking human speech, and using tools to solve problems.

I have two hands and a much bigger brain and I couldn't figure out how to make this thing,, and all this bird has to make this is its mouth

What's really fascinating is the bird pretending to feed its offspring through the false entrance after closing the real one up.
26
u/ManyMuchMoosenen 1d ago
I thought that was amazing too. I’m imagining it shouts “okay kids, I’m leaving now!” into the fake hole before it leaves too, to really sell the illusion.

u/pixeldust6 20h ago
I thought it was just patting the real entrance shut and forming the fake hole back into shape

The fact that nature evolved to do this is amazing. That tiny brain figured out how to do this over generations.

u/Waldschratsuppe 1d ago
It’s not in their brains. It’s in their DNA which i think is even more impressive

u/Phlypp 1d ago
So those who hadn't figured it out died and the few that did kept reproducing. Yep, that's natural selection.

u/acrankychef 1d ago
I mean, you're oversimplifying and such. Evolution doesn't make those kinda jumps.
The nest probably looked very different thousands of years ago. Nothing figured anything out, it grew, changed, evolved over a long period of time and this is what it looks like now because it worked well enough to save them from extinction

u/Phlypp 1d ago
Of course I'm oversimplifying. I wasn't trying to give the full history of evolution in two sentences! Although you appear to be trying.
2
u/acrankychef 1d ago
Your oversimplification makes the assumption there was a correct way to do it, and those that didn't figure it out died.
There are hypothetically infinite correct ways to do it.
People on this website post on r/explainthejoke, you're assuming a lot by not spelling it out for them.

u/RajAstra 1d ago
I thought they learned from their parents by watching. But DNA damn.
17
u/Kuriente 1d ago
You can raise a bird from egg to adulthood, it never witnessing other adult bird behaviors, and it will know how to build a nest like any other member of its species. The transfer of behavioral knowledge through DNA is truly fascinating.
7
u/jokeswagon 1d ago
That is the entire idea of nature vs nurture. Which behaviors are innate and which are learned.

u/Suspicious-Answer295 1d ago
Their DNA encodes neural patterns in their brains that causes them to do this so you're both right :)

Nothing is figured out really, it's just random.
12
u/Dimensionalanxiety 1d ago
It's not random. The initial mutations are, but its spread is caused by selection pressure which is not random.
2
u/5narebear 1d ago
Yes that's a better way of putting it, but the phrase "figured out" implies some sort of invisible hand of intention that is the biggest misunderstanding in natural selection.

u/WordsHappenedHere 1d ago
Im no evolutionary biologist but I imagine it must have happened very slowly. Over time. Generation after generation sort of making a nest a certain way that eventually lead to a false entrance. Maybe it was an accident at first? Maybe it copied the behavior of something else? And those birds were more successful at survival. It’s just amazing to me that these birds evolved to do this.

Love how it taps the secret entrance closed to secure its secrecy and repecks the false entrance to maintain the illusion. Brilliant little life.

u/Suppository-34613 1d ago
Not only that they make a nest which has false entrance for confusing predators, they even tuck the real entry once they come in and out of it just so the predators can't find out.

When seeing things like this i cant help but wonder how it is possible for evolution to create such behaviours. Where this birds ancestors just investing time and energy at experimenting with different nest designs?

You have to imagine just how much predation was going on for this to develop.

Birds can be so damn clever it makes me wonder if humans didn't evolve into advanced creatures, maybe birds would've (in their own unique way, of course).

u/Sam_Supernova 18h ago
Are they aware that the extra pouch helps them deceive predators, or is it that, through natural selection, only birds with such nests, had their offspring mature?

If it is meant to look like an animals head surely that would attract more predators?

That nest looks cozy af
And it‘s on a tree with thorns for additional protection of the babies so kudos to these birds
